Tank RO Units vs Tankless RO Units Review

[@SandTiger42]

I have the same tank RO system and just found out tankless is a thing. Came to your video while trying to find TDS test. Pleasantly surprised with results. I installed a permeate pump on mine so my water loss is 1:1.

[@punjabijugni7966]

Thank you for not making boring video about water. Good information what I want to know to make decision on tank vs tankless

[@nu11pointerexception]

Excellent thank you for the video. I am a home brewer looking for a RO system to purchase. You helped me make a choice for a tankless system.

[@maurairish8870]

How has this worked out for you plz!! I'm at a crossroad seems to me holding water would not be good! Not to mention crowded under stink!

[@hanzelnuts8446]

Thanks for the video. The one thing I'm interest the most was the water taste between the APEC and the tankless system. I didn't get to see that. I just installed the APEC ROES-50 system because I was tired of buying, carrying, and recycling. The APEC water system tastes amazing just like bottled water from Costco or Aquafina, not that crappy Arrowhead bottle water.

[@TheRealDavil]

Really no difference in my opinion.

[@axxiom20001]

I have same system. Try adding APEC's alkaline filter. Makes difference in taste and will help to add minerals to your water.

[@03Lorac]

😂🤣😆 you're comment is funny "yeah, tap water and new RO water tastes basically the same". Thanks for sharing.

[@TheRealDavil]

I'm not picky, I grew up drinking out of paper cups.

[@03Lorac]

@@TheRealDavil indeed, i even drank out of hoses as a teen. Realistically though, I'm genuinely concerned about the harmful toxins, so I'm researching for the most affordable tankless system that delivers quality results. The toxins i ultimately care about are chlorine fluoride lead arsenic micro plastics.

[@TheRealDavil]

@03Lorac I put in a whole house filter that covers all that the other day, dropped the tds number to about 300, and my girlfriend says the water smells better. So that is an option too if you can do some basic plumbing.

[@joephu]

The fridge filter or any water filter system will not remove the dissolved solids which is why the TDS doesn't drop. Only the RO membrane does this. Most of the dissolved solids is calcium and magnesium which is not a bad thing. It all depends what you are trying to remove

[@GabeAnguiano]

Thanks for the insightful video and I'll do my best to not die.

[@karimagha1]

Thanks

[@black6dog280]

Hey Davil, great video, one of the only of its kind on KZbin actually. Any update on the Waterdrop tankless system? Do filters last about as long as advertised? I've read a lot that TDS reading varies a lot in the first 10-20 seconds after the system sits for a while, anything noteworthy that you've seen?

[@TheRealDavil]

Thanks! I've replaced the filters twice since I made this video. The ro one once, so yea they do last as long as expected and the unit beeps when they need to be replaced. I haven't really noticed any increase in particulates in the water either.

[@saadmirza2727]

thank you for the informative video. i wish you would compare the flow rate of the tankless and tank unit.

[@TheRealDavil]

It's not significantly different, they're both pretty slow to be honest. It takes about 10 seconds per cup so quick math says about 2 minutes 40 seconds per gallon.

[@jeffgrant4234]

Tankless RO systems have RO creep. If you were to run it for 10 seconds instead of right away, you would have had a very higher TDS reading. After about a minute the TDS reading goes down again. This happens with all tankless systems.

[@TheRealDavil]

I'll give that a try and see what happens.

[@OcaOca]

@davil, what do you think after some years of ownership? I've read that tankless doesn't have a remineralizer as a last stage processor, so the water may have some effects similar to drinking distilled water.

[@TheRealDavil]

I ended up get a remineralizer and it's fine. It still works well and filters aren't expensive.

[@OcaOca]

@@TheRealDavil Awesome! If your water filter broke, would you get your old APEC or get another tankless WaterDrop?

[@joefairhurst69]

Hi Davil. Thanks for the video. I want to go tankless as I have very little space under my sink. I noticed that you tested your refrigerator water at the start of the video, is there a way, or some kind of attachment, that would allow me to run my water line from the RO to both the sink and my refrigerator? That would be great. Sorry if you have already gone through this--I did not read all the comments.

[@TheRealDavil]

The hose it comes with looks like it should fit but still have to tie in the waste water to drain somewhere

[@brianw6645]

I currently have the exact same Apec RO system you had. I'm considering making the switch to the same tankless system you did in this video. Will you please let me know how you like it after having it for a couple of years now? Thanks.

[@TheRealDavil]

Yea, I do like it a lot better if only because replacing the filters is so much quicker and it reminds you with a beep whenever you need to change them.

[@ddng2161]

Nice comparison! I couldn’t see that many videos like this, thanks! My RO system is aging, thinking about trying new WD system to save reduce some water waste

[@Prin_Cess_007]

Thx for review! How many gallons does tankless waste as it filters? Manufacturer usually understates their, wondering your real world opinion & how it compares to the tank RO systems. Thx!

[@TheRealDavil]

Haven't tested that but generally for tankless they say 1 to 1 compared to the 2 to 1 from my tank model. I can say that with the old one I could hear the waste water going down the drain, but with the tankless I don't, so it seems like less for sure.

[@rouletteplace]

Your first RO had a post filter which increased ppm. I have 2 and after Ro I have 3 but after filters about 50, the water is nice smoother.

[@OcaOca]

So you like the tank version better than tankless because of that effect?

[@wapperjaw8282]

The difference may be due to types of filters ... etc. My tank Ro System has a mineral filter. My tap water from Detroit is pretty good with around 123 ppm. My RO system brings it to zero, so I added a mineral filter to it now avg. between 13-20 ppm. *So what do the filters filter concerning the Tankless vs what do the filters filter with the Tank???

[@Chris-zu4es]

im 65 years old carpenter retired. never done any plumbing if i buy this setup would i be able to install it my self easily or super easily or is it pretty difficult?

[@TheRealDavil]

Super easily, I'm not a plumber or carpenter I just do a lot of work around my house and for friends. The hardest parts are drilling a whole in the drain line for the sink and wiring an outlet if you don't have one already.

[@Chris-zu4es]

[@SeanHawthorne83]

This was well done. Thank you.

[@blkinvestor]

@davil why do you have two faucets? What do you use the non-RO faucet for?

[@TheRealDavil]

The water coming out of the ro unit is very slow and doesn't have much pressure. The normal sink is for washing dishes and other stuff that I don't need drinking water for

[@PorphyricSteve]

Thanks a lot man, this helped me make a decision. Great video.

[@dr-ii2mw]

My kitchen is set up so i have to run a water line about 15 feet from my sink. does this provide enough pressure to accommodate both sink and fridge?

[@TheRealDavil]

I don't know if you can do both at the same time. Should be able to split the water line to the faucet and go to both though. They make a refrigerator connection kit so it's for sure possible to get water to both, just not sure if the pressure would be enough

[@varunmiriyala351]

Thank for the Video. How is the sound coming out of the tankless system? Some reviews on Amazon say that the sound from it similair to that of dryer.

[@TheRealDavil]

It's not extremely loud, I would compare it to a small circulation pump for a fish tank or a d5 pump for computer water cooling, it's noticeable if you're listening for it.

[@AltruisticWarrior]

The one I bought has a battery to operate the filter reminder but otherwise there's no noise but water moving through the pipes basically.

[@pearldiver2779]

Have you tested the tap water after letting it sit on the counter for 1 hour? The chlorine is said to evaporate after a while, and maybe the test would show lower TDS without the filter systems?

[@TheRealDavil]

Haven't, chlorine isn't really in my water though from what my test strips say

[@mustang5gtx]

You can even tail by the difference in color in the RO water that it's better quality.

[@miapapa1955]

Thanks,Overall a good video.

[@shoppersplace]

what brand was that tankless ro? thanks

[@TheRealDavil]

Waterdrop is the brand, still going strong.

[@TheLovey22]

How is the Waterdrop working one year later? How often do you need to change the filters? Any issues getting filters?

[@TheRealDavil]

Only been 8 months so I haven't had to replace them yet, still working well though and I ended up getting a remineralizer since it's supposedly healthier. I didn't see any issue with getting filters though, still plenty on Amazon.

I couldn't tell you because I added a remineralizer. But even with that I get about a 22 and I haven't changed filters yet.

[@shorterstax]

Does anyone know what are the main differences in Apec's rotl models? they have 3, one(in the video) and then 2 others that around 600$ (of those 2 one reintroduces 'minerals'). im just curious why is there not an easy way to compare these 3 similar models specs on their web page for a few $100s more in price. The 600$ also have the filters in front and have 3 separate filters vs the lower budget one which is just one, but spec wise i see no difference

[@kainaat8242]

[@karamedina4136]

How and where did you add the remineralization filter to the new tankless system?

[@TheRealDavil]

It goes right before the faucet. You just have to cut the tube that goes to that and plug the remineralizer in.

[@Hertz2laugh]

You didn't ask for my opinion but, as a ex water filtration salesman, I can tell you that remineralizers are kind of a gimmick - you're getting 99% of your minerals from solid food. Spend that money on quality meat and veg instead. Best wishes, Random internet commenter

Minerals are just for taste, not some health benefit.

[@markriofski6129]

You mentioned the flow quickly. Do you notice if the WD is slower than the traditional in filling up a glass?

[@markriofski6129]

@@TheRealDavil Good deal appreciate it. As long as it's similar enough the family can't complain

[@firecaptdave1273]

Good video. Since the pump turns on when you run the sink, what about hooking it up to a refrigerator ice maker (I’d split the the line going to the faucet.) Would the ice maker have enough demand for the pump or would it cause the pump to run constantly, etc.?

[@TheRealDavil]

I would imagine anytime there is demand it will turn on so it should work. Ice makers generally just pull water to fill the tray so would run all the time.

[@Natedoc808]

It will meet the demand of the ice maker so long as the ice maker is asking for water, which will cease once the ice tray is full and trips the shut-off lever.

[@andriifediuk7274]

Super helpful thank you! One question did you try to test water from battle ? I’m just curious what tester can show

Depends on the type of bottled water. Some like Voss or smart water are basically 0. Others like Dasani are essentially tap water

[@1TUFZUK]

I would never drink from disposable plastic water bottles. For 1, those things sit in warehouses for ages, toxicity and chemical leaching happens on those plastics.

@@sandragarcia3454 R.O. basically strips everything out of water, including minerals. Water salesmen use this to freak people out and scare them into buying remineralizers (I know this because I used to work in the water filtration industry). The reality is that humans get all the nutrients they need from *_solid food._* There's no way your health is going to be negatively impacted by not getting the minerals from water. Instead of spending on a remineralizer, just buy quality meat and veg.

[@guidedbygreen1480]

If you have a water softener, then you likely have hard water. Hard water is water rich minerals such as calcium and magnesium. A water softener reduces these minerals and replaces them with high levels of sodium. Which is why the water feels slimy. Now an RO SYSTEM removes all disolved solids, including your added from softener sodium now. I believe the added sodium is no good for a baby or anyone to drink, and thus an RO system is beneficial. Water is at a PH of 7 (not 8), and RO water is slightly acidic because of it's void of minerals. So I advise that you add US calcium carbonate remineralization filter as the final filter on your system.

In my case the dishwasher is on the other side of that cabinet so I cut a hole and mounted a new outlet box.

@@hellapellanyc6465 just like your dishwasher discharge, your RO waste/drain line needs to be on a high loop. High loop is when you have the tubing looping above your sink, tacked up at the highest point in your undersink cabinet. by doing this, you are ensuring that you have no black flow coming from your drain and all of your waste is going where it needs to be. before high loops were allowed, an air gap was required. in this circumstance, a high loop is fine.
