Reverse Osmosis Troubleshooting Water Continuously flows to Drain

[@HelloNNNewman]

Thank you so much for this video. I bought a home with this system installed and I noticed the drain line from the last cartridge seemed to be running constantly. After going through your steps, I verified all was well and the tank was refilling after I had gotten some water earlier. Saved me a call for service to check it! Thanks for your videos on this system - very helpful! 👍

[@lauriebradley406]

Thank you for these videos. I come back to them time and time again. My RO system was in our house when we bought it so I had no idea how to use or take care of it. So far for the past 4ish years I have been able to resolve all my issues with your help alone. It has been especially useful during this pandemic when a service call is not so easy! I am in Oshawa Ontario and consider it a bonus to have found Canadian made videos that are relatively local too! 🇨🇦 Thanks Gary!

That is awesome! Glad it was helpful! Please share with friends and family.

I replaced the AOS and the check valve. The water continues to run. I did make one mistake,.... I yanked the black line out before reading the tag on it. I was able to plug it back in but worry it is damaged. Also, would an old membrane cause the water to constantly run? Mine is a probably 5 years old.... I think I already know the answer. LOL. Thank you.

[@GarytheWaterGuy]

Yes, an old membrane would cause water to run to drain. Also, if you black line is your drain line you might have dissolged the DLFC or drain line flow control.

[@berockization]

A tank with too low air pressure caused my system to drain continuously. Draining the tank of water and re-pressurizing it to 7.5 psi fixed it (I mistakenly released some pressure when monkeying around with the system before I knew how it worked).

[@JLMABIO]

How do you repressurize the tank to 7.5? My RO System is brand new and it constantly runs and water goes to the drain and the drain does not get filled. When I shut off the tank’s valve the draining stops in like 15 seconds, so I assume it is not a problem with the check or the ASO valves this video talks about. Any thoughts? Thank you.

[@berockization]

I have a WATTS brand 3 stage reverse osmosis system that drains continuously making that gurgling sound down the drain. Manual states, 4-7 PSI in empty tank. I pumped 7 PSI. Still drains continuously. I have that automatic shut off valve with the 4 lines going to it. Green & Red in & out. I've pumped 10 PSI into the tank and still drains continuously. Installed new filters didn't fix it. Is there a way to bypass this to stop it from draining, losing filtered water down the drain? My State doesn't have that safety code that's so called required to have in other States. Thank.

Did you check the automatic shut off and check valve as discussed in the video?

@@GarytheWaterGuy This Watts System has a automatic pressure valve. Has 4 screws to take apart. I took it apart and found there was rust build-up. I reassembled it. Works again.

hmm... i still don't get it. I just got the new Pure H2O system. When i first turned on the water, i could hear the water flowing and some noice coming from the faucet. The black tube constantly spill out water, is it normal? That's like wasting water.

@@GarytheWaterGuy kzbin.info/www/bejne/r4uZhH2JftNmoLs Yes, I have just got another of your video shows that. Thank you so much!

[@ActiveT08]

It could be the Pressure tank is very low on pressure and the pressure differencial is too wide. The Automatic Shut off works based on pressure differential but if the difference is too wide, the pressure from the low pressure chamber in the ASO will not push the piston into the high pressure chamber of the ASO and thus not allowing for the stoppage of flow to the RO Membrane stage. The pressure from the cold water inlet will then push right through the RO system and continuously drain.

[@GarytheWaterGuy]

Yes, the manufacturers typically recommend 25 - 30 psi minimum.

[@davebarone9507]

Gary, your explanation was clear but your visual of the RO system is shown backwards and when you point to the check valve it’s not visible. That filter you pointed to, which is the larger one has two outlets on that side and white one where I’m assuming the 90degree fitting is a Ck-90 check valve and the other outlet is black- waste. Is it a 90 degree Ck- valve ?

[@johnbentley364]

Could the ASO be bad even though draining stops when we have supply on, tank off? I started with shutting the tank valve to simulate a full tank. Supply water runs through the ASO through the membrane, through the check valve, then stage 5, back through the ASO to the Tee where it would then go to tank or faucet. Both are shut, so it backpressures to the ASO and shuts the supply water to the membrane. Draining stops. So the supply water is acting as it's own shut off. When we do the second test, supply off, tank on. There's no draining. Because there's no supply pressure to stop the tank water going through the ASO, back through stage 5 filter, and then deadheads at the check valve. So then the problem with the constant draining would be that when the system is on. Supply on, tank on. The tank is full, but the ASO isn't stopping the supply water going to the membrane, backpressuring off the full tank, and out the drain. Does that sound right to you?

[@johnbentley364]

I replaced the membrane and it continued to drain. However, I did miss a step where I didn't open the faucet right away and I had some air pressure shoot out the faucet. Following the instructions in the video, it seems the ASO is bad, but is it possible I damaged the membrane and it was constant draining from an old membrane and then draining again from a damaged membrane?

[@johnbentley364]

I then took the ASO and reversed it's direction. The problem moved. Instead of the constant drain stopping when the tank is shut, it constant drained from the supply. I had already taken the ASO apart to see what's inside. So I don't believe the shuttle really cares which side it's facing. The color coding seems more to ensure that both colors go on one side or the other instead of same color on top and bottom. I'll update once the new ASO arrives, but I still want to know from you if it seems I understand why we test it the way we do in the video.

[@GarytheWaterGuy]

No, I doubt it.

[@GarytheWaterGuy]

It could be that the aso is ruptured inside and is allowing water past it's internal diapgram.

[@johnbentley364]

@@GarytheWaterGuy New valve arrived and it's working now. I also drained the tank and checked the pressure on the bladder. I'm wondering if that was the real issue because none of my guages read anything. I had to rely on the bike pump guage to reach 5-6psi. Hooked it all back up with the new ASO. Waited an hour and a half of more constant draining, trying not to touch it until the tank had time to fill, and it has now... finally... stopped draining. It has been driving me nuts for the last few days with nonstop draining. This entire event has basically fired the company that installed it from coming back out. They were called out for the draining noise it was making. Some miscommunication on the homeowners part due to a previous air noise it would make. The tech did an inspection and only noted that the filters needed to be replaced. I'm guessing the homeowner declined filters. Until I said something about the draining and I asked about the filters. This is where I stepped in. Filters were ordered, and replaced. It was missing the sediment filter and had a carbon filter in stage 1 with stage 2 empty. The tech should've noted this. I took the time to learn the circuit (as you read above) and was scratching my head on why it wouldn't stop draining. Because it was constantly draining. So by this point I've gone through all the procedures and the system now works again 👍 I reached out to verify that I understood the "why" part. I appreciate your quick response.

[@AM2PMReviews]

Seems like every 2 years I have constant running after replacing the auto shut off valve so this time I turned off the tank I’ll draw two or three glasses of water, and I don’t hear it. But when I open the tank it just runs forever. Could it also be the tank bladder isn’t pumped enough to give enough pressure to get the ASV to work? I am assuming that is the issue when it’s really warm in Phoenix. Edit: I just replaced the ASV now and it didn’t seem to work Edit: so maybe a pump of air in the bladder will work.

[@GarytheWaterGuy]

The tank should have 7 psi of water in it as a pre charge when it is totally empty of water.

[@AM2PMReviews]

@@GarytheWaterGuy yes I did that. and I changed the ASV and replaced the flow restrictor and now what? maybe the city is just putting out less water pressure?

[@AM2PMReviews]

I replaced the check valve. And checked the PSI and replaced the ASV. I replaced the flow restrictor and flushed the system. Nothing seems to be working. Oh I just realized it’s very very slow to stop the running. Like take a glass of water the waste water will run for like 15 minutes it seems. Then it stops.

[@thebodymaster]

You are incredible. If I may ask, I did as you suggested. I closed the valve on the tank for 5 minutes. Then physically disconnected the drain hose and no water. However once I turn the tank valve back on, it continues to drain but my system pressure *not tank pressure* is now at 0

[@GarytheWaterGuy]

I would confirm thatb all of the connections are correct. If so, it sounds like you need a new ASO valve, we ahve them here waterestore.com/products/reverse-osmosis-aso-asv-4000q

It depends on a number of factors like the gpd capacity of your system and yout TDS but typically anywhere from 20 minutes to 4 hours.

No. All you have to do is pump the air pressure to the correct PSI and while closed connect the line to the tank, ensuring everything is properly connected (while your RO system's water shut off) and then slowly turn on the inlet valve to your RO and finally it's safe to open the shut off valve to your tank.

Noticed that the aso vavlve is between sediment and carbon cartridge, and when i twisted off the sediment cartridge it erupted from the top of the aso valve. Got a new aso valve, still nothing. Decided to untwist and retwist all the newly installed cartridges and bam, the water started flowing. It had to have been the aso valve because the old cartridges were less than a year old and i put back on the old membrane as it was not plugged and am getting good water now. I test my water softness regularly and its benn 1 GPG. Mind you i used to sell ro and softeners, so this was driving me absolutely crazy.

[@monkeymazikeen6098]

If either of those or both are bad? Will the extra water start to fill up the sink. To where it looks as if you drains a clogged?

[@GarytheWaterGuy]

No, water will just keep running to drain.

[@baskymdu]

The video and the explanation is really helpful. My drain was going on non stop. Based on your logic, i figured it out that the Check Valve is a problem.. tried to buy in your store.. didn't find one. Can you help ?

[@EG18-t4m]

Thank you for your video. I have replaced all the filters, the membrane, the check valve, the ASO, the drain tube, and my system is still constantly draining. I also drained my tank and pressurized it. The tank won’t fill now because the water constantly drains. When I close the tank, I get a tiny trickle out of my faucet and a strong flow out the drain. Please advise if you have any tips. Thanks!

[@GarytheWaterGuy]

For sure the tank has only 7 psi of pressure when it is empty?

You may have excess air in your water which would make the ice cubes look cloudy.

[@victorvega4266]

Water continued flowing drain line

Likley either the membrane or ASO valve.

hi I was looking at the guage at my water bladder early and the presure keeps goind down on its own without any water running anywhere in the house cousin pump to keep coming on every 30 seconds or so.. please help

[@soumitradas6144]

if i accidentally close the RO system outlet valve what may happen?

[@fern9234]

Hi, thanks for the video. My issue is that it seems that my unit is running more often. It shuts off promptly. Also, it seems as if it runs out of pressure towards the end of a water bottle fill-up that it used to be able to handle without losing pressure or cycling on. Do I need to fill the inner bladder with more air or can it be another problem all together? Thanks for info.

[@niteriderband4713]

Here you go, lessons I learned the hard way (my ASO valve would not operate correctly): 1) Make SURE you understand the IN & OUT ports and hook up the lines correctly to ASO valve. 2) Use ONLY hard lines to interconnect (dont use clear lines from home depot, they are too soft and valve wont shutoff correctly). 3) Keep all hard tube lengths to ASO valve as short as possible. 4) On all connections make sure the tubes push all the way down 5) On all post carbon filters, post filters, etc...dont plug directly into these filters, first always use a push in connector then push your tube into those connectors. I did all above and fixed my ASO valve RO system operation.

[@GarytheWaterGuy]

Thanks!

My chiller stopped chilling the water, any suggestions?

[@csbkburrell5018]

Thanks, We started to worry that our ro wasn't working because it seemed to be running for a long time. We watched your video, and you said in about 4 or 5 minutes it should stop running. By the time we finished watching, we checked again and it had stopped draining. Thanks.

Thank you so much for the video. I have the same issue and would like to ask one question. I pulled out the drain line to perform the first part of the test and the water wouldn't stop flowing when the tank was closed. However, when blocking the drain line with my thumb, the water stopped immediately after 5 seconds. When the water supply is off and the tank valve is open, the water does not run. Is that still a problem with the ASO or it can be the flow restrictor?

[@rohitbarar]

Hi Gary, great video I have replaced the ASO, check valve and verified 7-8lbs pressure in an empty tank. I still have continued water flow from the brine line though. When I shut the tank valve, water does stop to the brine line. Also, if I shut the tank valve when the tank is full, it does trigger the ASO to shut, but that is the only way to stop the flow. Do you know what else I can try replacing? Perhaps the flow restrictor? (100gpd filter with 600ml restrictor). Thanks!

[@GarytheWaterGuy]

I would think the check valve is the problem since you say the flow stops when you close the tank shut off.

[@DavidNelson42]

I performed the first test, ie start with full thank, then draw 24 oz water. It began to drain. So I shut off the tank valve. The water stopped immediately. When I reopened the tank valve it began to drain again so I timed it. The system drained for 10 minutes then stopped. Is that normal?

[@GarytheWaterGuy]

Whenever it is making ro water to fill the tank water runs to the drain. If the tank is full it will shut off.

[@rockodille01]

One more cuestión ... What is the best point to place a pump for boosting pressure and activation valve (pressure switch)?... In system Ro

[@GarytheWaterGuy]

Flow switch should go on water line going to tank.

[@Bobby-lv2kr]

I collect waste water in a container and I have noticed significant increase in quantity of waste water It happened after I used a different brand filters, Also I have noticed 10 points increase in pressure gauge which is installed between pump and ro membrane, Anyone knows what could be the reason of this increase in waster water or pressure?

[@GarytheWaterGuy]

How old is the membrane? Any idea of what the TDS is of your water in parts per million?

Hello, congratulations for these videos, i have a trouble with my system it is a water express system, that system was working perfectly but i moved to another location and the wather always flow to drain never stop, what i can do?

Did you try all of the suggestions in the video?

[@chrissmoke2117]

Is reverse osmosis on a backflow device?

[@blackmarketbarber]

Is it normal for the water to simultaneously exit the drain while the tank is filling? Thank you! Great video.

[@GarytheWaterGuy]

Not 100% sure what you mean. If you mean is it normal for water to be running to drain during the refill cycle, no. If you mean during the brine draw cycle, yes. You might find this video helpfull kzbin.info/www/bejne/q5XQdmCenc1jbpY

Restrictictor needs to be replaced . There’s different colors coded restrictions 24 , 36,50, 75 gpd. Anyway when you replace membrane you should have replaced restrictir too.

[@fangyang8563]

@@Sam-od4xb Is it flow control inserted in the drain tube?

[@jassonmoreno2025]

I have a question it may sound kind of tricky. ¿ Is the water that comes out the Reverse Osmosis Storage Tank when re-inflating, filtered and safe to drink as well ? or ¿ Is not safe to drink ?

[@Andy-im3kj]

Yes, presumably if everything is connected properly and in working order, the stored water is of the same quality as the water coming directly from your RO system.

[@jasonchipkin]

Very good, thorough explanation. I have a question that I don't see addressed specifically too often... About how many cups of water should you be able to fill before the system begins to fill up again? And - for how long should that filling take? It seems as though mine runs for almost an hour or so and it's loud and bubbly and shouldn't take that long to refill. Thanks!

[@turgutldk9878]

Hi. Gary. Your explanation is very clear. Thanks so much. I'll ask a question. I replaced in order ASOV and Check Valve. It is shut RO continuously flows to drain when the tank vane is closed. But although I had replaced new membran and all filters, still the drain water is running non stop. What caused it is? I don't understand any. Can you help me please? Thanks now.

[@turgutldk9878]

I know what you said. my trouble is solved. Feeding water pressure had too low. So I activited RO pump. Then drain water is shut.

[@jechkael1116]

Couldn't the flow restrictor on the drain line also be the culprit?

[@GarytheWaterGuy]

Good Question. No it really could not. The decision to shut off the water occurs in another area of the RO system.

[@hiloboy11]

My system has an adjust knob between the membrane & drain pipe. What is it? Should position be on or off? Thank you.

[@hiloboy11]

I believe it is the by-pass flush valve after google. However, after I turn off this knob, water is still draining to the pipe. Is it normal?

[@JLMABIO]

Gary, our RO System is brand new and it constantly drains water and the tank does never get full. When I shut off the tank’s valve the draining stops in like 15 seconds, so I assume it is not a problem with either the check or the ASO valves this video talks about. Any thoughts? Thank you very!

[@GarytheWaterGuy]

The video says "Turn OFF the Cold feed water supply and open the tank valve. Check the drain line, if water flows then this water is coming from the storage tank which means the Check Valve is broken. If no water drains out from the drain line this means the ASO is defective and needs to be replaced."

[@PartlySunnyTV]

@@GarytheWaterGuy I'm not sure I understand. If there is water flow, the unit is broken. If there is no water flow, the unit is broken. How can both values be different yet the same.?
