Troubleshooting an American Standard Selectronic Flushometer | Repair and Replace

[@ShiverPlumbingTN]

Great direct explanation! Just fixed 2 @ church and was not familiar w selectronic auto flush valve

[@AmreSupply]

Thank you, we're just happy to help!

[@ottocrg]

Very well explained thank you. If I understand correctly, it Is the sensor (an its capacity), the single piece that dictates how much water will pass trough? Many thx

[@AmreSupply]

Thanks for watching. It is not the sensor that controls the volume of the flush, it is the piston. The rate of water that trickles back into the upper chamber will change how long of a flow there is.

[@dalealexander4860]

Is there adjustment so the unit won't flush while I'm still sitting on the the toilet, any movement active the flush.

[@AmreSupply]

Thanks for watching. You can see the sensor calibration steps in this video: kzbin.info/www/bejne/qqm2aGWHeNGWitU

[@Workyoutube-x7z]

Can you change the range of where the sensor picks up motion. It seems to only pick up motion less than an inch away.

[@AmreSupply]

Thanks for watching. Yes you can calibrate it. We made a video showing how: kzbin.info/www/bejne/qqm2aGWHeNGWitU

What can be done for water hammer? I have one that causes a lond bang when the piston closes.

[@AmreSupply]

Thanks for watching. Water hammer is caused by a shockwave from high pressure water which suddenly stops (when a valve closes). Loose pipes will exaggerate this effect and will create more noise. A water hammer arrestor can be placed between the supply and the flushometer to reduce the severity of the shockwave, reducing the noise. www.amresupply.com/search?q=water+hammer&categories=WaterHammerArrestors

[@aaronsadventures7739]

How do you control how much water when it flushes automatically? It does not flush long enough to empty the bowl.

[@AmreSupply]

Thanks for watching. Water pressure can be slightly adjusted, it can be worth opening the control stop to see if it helps. On the other hand the gpf (flush length / volume) is controlled by the piston. It is possible that the piston inside the flushometer is mismatched to the toilet.

[@joeyperez]

How does the manual over ride button works? The sensor can flush automatically but the manual (push valve) wont. Any troubleshooting tip? Thanks

[@AmreSupply]

Hi Joey, thanks for watching. The manual override button releases water from the upper chamber (it bypasses the sensor and solenoid). If the valve flushes normally via the sensor, but won't flush when you press the button then the button is likely faulty and is sticking or not opening properly. It's been 5 years since we've filmed this. I don't have this model in front of me but I think this button is not easily replaced on these models. We also don't sell replacement buttons so we don't have a video for the button. All American Standard Flushometer videos can be found here: kzbin.info/aero/PLCo9SMjkdWBypfd69rUJSWqCYqFVDvAzw

[@nobark1]

My plumber accidentally hooked this to the hot water line. ( on a urinal ) Could this cause any issues? It's a tiled wall and would be a pain to change it to cold side.

[@AmreSupply]

Thanks for watching. Urinals and flushometers are not designed for use with hot water. Depending on how hot the water is, it could reduce the lifespan of the piston. It might also smell worse overall as the hot water will cause some odors to vaporize as it evaporates. It is unlikely to crack the urinal bowl unless the bowl is very cold before the hot water is run over it.

[@craigbennici4116]

I have a unique problem that wasn't listed in the video. The sensor can go off but it doesn't flush and whines in its attempt, but the side button functions perfectly. I've tried changing the inlet valve flowrate, different batteries, and testing the wires and everything seems to be working fine in those regard. I was thinking I would need to change the solenoid entirely but I don't know if it would somehow be the vacuum breaker or some other easier/cheaper fix. Any help would be great, thank you! (I will comment my results in case others have this problem in the future)

[@AmreSupply]

Thanks for watching. If the flushometer works with the manual button on the side, then it's likely an issue with the solenoid. If replacing the solenoid doesn't fix it, then it could be an issue with the sensor module.

[@craigbennici4116]

@@AmreSupply I did end up replacing the Solenoid and the system works fine now for the most part. The button works to flush, and when the sensor DOES trigger, it flushes perfectly. However, i think my sensor has gone bad as it doesn't trigger anymore. I tried looking for a replacement sensor but couldn't seem to find one. Could you provide a link or the information id need to find one myself please? Thank you for your help!

[@AmreSupply]

@@craigbennici4116 You'll have to double check which exact model you have but you can search by model number on the AMRE website. This will bring up a parts breakdown.

My new American standard selectronic flush valve makes a banging noice in the pipes and does provide much water at a flush. Any solution for me?

[@AmreSupply]

Thanks for watching. Was this a new installation in a new building, or did this selectronic flush valve replace an older valve?

[@matthewchan8539]

where can i buy this specific sensor , is there a direct link i can use?

[@AmreSupply]

Thanks for watching. You can browse sensors here: www.amresupply.com/catalog/Electronics-PF14 As for American Standard, it depends on what model you have as the sensors are based on the GPF. If you do a google search for your model number there are parts lists in PDFs for those models. It's best to double check this on your own but you'll likely see these sensors listed.

My urinal is getting stuck when flushing with continual water causing the urinal to over flow. Would removing the manual override button and lubricating the O-rings help the manual button not stick anymore?

[@AmreSupply]

Thanks for watching. Continuous flushing can be an issue with the piston, the solenoid or the manual override button. It would be good to listen for the solenoid, sometimes you can hear it click when it opens. As well make sure that the piston is functioning correctly. Check the manual first, most recommend NOT to use pipe sealant or plumbing grease on any valve component or coupling except the control stop. Alternatively if you think the override button is sticking and is causing the continuous flushing then it will likely need to be replaced as it would be sticking internally.

[@machdw650]

I have replaced the battery pack and tried 2 piston/solenoid assemblies and it is still letting water pass through in to the urinal without flushing.

[@AmreSupply]

Thanks for watching. If you've replaced the battery pack, piston and solenoid then it's likely an issue with the sensor.

[@elitesk333]

I have 2 selectronic toilets where it flushes manually, motion sensor works, and i hear a click inside i assume it's the solenoid, but they still don't flush automatically. They have new batteries installed.

[@AmreSupply]

Thanks for watching. It could be an issue with the piston. In these models the piston has a channel to release the water from the upper chamber. If the water doesn't release from the upper chamber then the flush will not start. Pressing the manual button should still work in this case as the water will run through a separate channel to initiate the flush. You could try cleaning this channel in the middle of the piston with a wire or try installing a new piston.

[@morrinsondulce4540]

Hello, how can I solve my problem with my tape measurer model 6065121mx, it does not stop spewing water, the solenoid does not activate and the piston does not activate it - the manual button gets stuck, how do I solve it, thanks

[@AmreSupply]

Thanks for watching. Sometimes minerals in the water can build up and cover the inside of the valve. This can prevent the flushometer from working properly. If you take apart the flushometer and give it a good clean, that can sometimes help. If not then a new piston or solenoid might be needed.

[@bobforpples]

The toilet seems to flush only halfway when sensor is activated after changing vacuum breaker. With override button it flushes fine. Any ideas?

[@AmreSupply]

Thanks for watching. Since it flushes properly with the override button, it means that it is able to let all the water from the upper chamber out in that case. Perhaps check how the solenoid is seated to make sure there is nothing preventing it from opening up properly.

[@franciscoarias6245]

Having issues with the one we have at work, everything works as it should EXCEPT when it flushes, I can still hear water running and when you fiddle with the button it suddenly starts flushing none stop and I’m not sure what else I can replace, it’s practically a brand new unit

[@AmreSupply]

Thanks for watching. Does it stop flushing when it runs in the automatic mode or only when you press the manual bypass button? If it only happens when you press the button, then it likely isn't closing properly and is letting a small amount of water through, preventing the upper chamber from filling with water, and pushing the piston onto the valve.

[@ltassnime]

What could be the cause for a sink where I replaced the most parts but still no water coming from the sink please thanks (American standards)

[@AmreSupply]

Thanks for watching. For a Selectronic faucet to work the battery(or the AC power supply) must be good, and the sensor needs to functioning correctly. The faucet will use a solenoid valve. This can fail electronically or mechanically. You can look up a parts breakdown using your model number to get a more detailed view of the parts inside of the faucet. There is some variation between models.

[@Mattyehdams]

My problem is I can only get a yellow light to flash on when I hold my hand super super close. Not ones have I got the red light to turn on

[@AmreSupply]

Thanks for watching. A Yellow LED indicates Low batteries. If all of the models were installed at the same time it is possible for the batteries to be at a similar level.

[@Mattyehdams]

@@AmreSupply no batteries it’s wired to a transformer.

[@paulhebert684]

I have a few 6065 flush valves with continuous flush. I swapped out piston assassembly with another in the room and works fine. Seems on ones with problem the manual push button seems to be the problem. Is the a way to remove push button and lubricate o-rings?

[@AmreSupply]

Hi Paul thanks for watching! The override button can be removed and replaced if needed. www.amresupply.com/part/M950354-0020A-AmericanStandard-Flushvalve-override-button There should be a retaining clip that you'll have to pull off first before removing the button. Lubricating the o-rings might help if water is leaking through the override button. If not a new button, or new o-rings might be needed.

[@russbell6418]

Nope. Crap design. You can cut the end off the center pin with a grinder, but it will no longer function manually.

[@steveholenstein8791]

Vance, toilet flushes fine, automatically, but push button override gets stuck and toilet runs continually. I suspect the o-rings are hanging up; can I lubricate with a silicone paste? This toilet doesn't get much use over the course of a year's time; if anything it suffers from lack-of-use!

[@AmreSupply]

Thanks for watching. Yes a silicone based plumbers grease can be used on the o-rings to prevent them from sticking. Silicone is best rather than something like vaseline. Vaseline is petroleum based and can cause the o-rings to deteriorate.

[@chrism8595]

@@AmreSupply I have the same issue. I can't find instructions on how to replace the manual over ride flush valve anywhere. Can you post instructions or a link? Thanks

[@AmreSupply]

@@chrism8595 Thanks for watching. The button M950354-0020A is harder to find than other parts. We didn't film a video on it but I'm pretty sure it can be unscrewed similar to this video: kzbin.info/www/bejne/ipOQgoWvm7mHick In the case of the American Standard model, you'll likely need a hex wrench to first remove the set screw that holds the button cap in place. From there you should be able to get a wrench on the button to unscrew it.

[@kylemcmillen5634]

I opened my small can of wd-40 doused the manual override and it quit sticking. Wd-40 works like a charm. Finding parts for these is worse than looking for a clean manual transmission.

[@tjrktm]

I've got continual flush after replacing solenoid. Before replacement it was only flushing manually and light was flashing but no solenoid clicking.

[@AmreSupply]

Hi Tim, it sounds like the piston could have shifted during your solenoid replacement. There is a little spring inside the piston, which is used for self cleaning of the bypass hole to let water into the upper chamber. Check to see if the spring is still there and if the bypass hole is clogged.

[@russbell6418]

Also often cause by stuck manual pushbutton. They are not repairable. Compare the exterior of the pushbutton to another valve, or see if the center pin on the inside (about 5/16 diameter) is sticking out past the main brass pin of the push button.

[@kylemcmillen5634]

Just came across one of these overly complicated flush valves. Turns out a dead battery can cause solenoid or piston sticking. New battery worked like a charm.

[@orinjules]

My toilets are not flushing completely. Can you provide more information on what pressure the water supply should be, length of pipe etc.

[@AmreSupply]

Hi Orin, Its best to check the Selectronic manual for the recommended pressure for your specific model. As for the flow rate: There are flow meters that can measure the flow rate at a given fixture but that won't reflect the flow rate capacity of the whole system. For more information, this is a good read: inspectapedia.com/water/Water_Flow_Rate_Measurement.php

help....mine does not flush long enough.. toilet is 1.1gpf to 1.6gpf and sensor is 1.28gpf

[@AmreSupply]

Thanks for watching. Just to clarify, do you mean that flushometer sometimes flushes at 1.1gpf and other times 1.6, and all the way in-between? Is there any consistency to it? Does it flush enough to clear the bowl?

[@triftonhuff4053]

AMRE Supply Hello, I have an American standard touchless toilet 1.6 gpf. When the toilet flushes from the sensor it does not flush fully. I have adjusted the set screw in the inlet valve , replaced the seloniod valve and piston. The battery is new. Toilet is 3 yrs old and has worked fine up until now. Any ideas? Only thing I haven’t replaced is the actual sensor itself.

[@RT-lh5ml]

I have this flush valve on a urinal at home ( about 2 years old ) It flushes properly, but there's a small, slow but steady stream running down the urinal. I turned the inlet screw all the way in, ( to test ) but there's still a slow trickle. What should I check to repair that ? Thank you.

[@AmreSupply]

Thanks for watching. Its likely an issue with the piston. If the rubber on the side of the piston is not making a good seal then water will continuously trickle out of the flushometer. The repair can be seen here: kzbin.info/www/bejne/mYLKkKyIbdygr5o
