How do I replace an outlet valve washer

Yes. It appears to be a straight forward retrofit. Use a new flush valve and fill valve. You can DIY this without any problems. Remember to buy a suitable flex hose for the replacement fill valve to make installation easier and be aware that the isolation taps/valves on toilets have a tendency to leak after being shut off from not being touched for years due to corrosion and the washers going hard.

For $290 is savings, I'd work at backing that piece out ... someone has put it on.

Cut off power to unit. Cut off water. Take front kick plate off. Remove incoming water line from old valve. Squeeze the clamp on the outlet side of the valve and move it up the line. Remove outlet water line. Take old valve off frame. Unhook wires from old valve. Take new valve and reverse the steps to install.

The American Standard Cadet 3 flowise one piece toilet uses a flapper valve with a soft nylon washer to seal against the water outlet.
Over time this nylon washer develops 'puckers' causing water to seep between the nylon washer and the seat of the flapper. This seepage causes the water level in the tank to drop to a point where the water inlet valve opens to replace the lost water in the tank.
There are two ways to correct this problem:
1. Replace the soft nylon washer on the flapper, or
2. Replace the entire flapper valve.
Hope this solution helps.

2 possibilitiies here.
1- the water inlet valve/s are leaking past the seal as the the washer is stood, remedy, replace the valve/s.
2 If fhe outlet pie is connected toi the sink waste, then water could be syphoning back from the sink into the washer.
Remedy, lift the outlet hose up higher than the bottom of the sink waste outlet.

A couple of possibilities here.
It could be a sticking water inlet valve, or water syphoning back into washer if the drain outlet hose is joined into the sink waste outlet.

To check which it is, turn off the water supply to the washer and leave for a day or two, if no water comes in, then it is a sticking inlet valve which will have to be replaced.
If water still comes in after turning it off to the washer, then it is the waste outlet pipe that will need to be lifted up higher to prevent water coming back into washer from sink waste.
Please rate my solution.
Thankyou.

There are 2 possible reasons for this to happen.
1- you have a sticking water inlet valve, turn off suuply and see if it still fills, if it does not, then the valve or valves need to be replaced, if it still fills, then water is probably coming from sink waste if the drain outlet is connected to same, in this event, raise outlet hose higher up to stop syphoning action..
Pleaase rate my solution.
Thanks.

Hi, It does sound like the inlet valve is bad. If the screen inside the inlet vavle is not plugged, you will most likely need to change the valve. If you will send me a model #. I can tell you how to get to the valve for replacement.

Thanks

HI. i would check the water valve inlet screens and make sure that the wall outlet faucets are fully open. if the screens and the wall faucets are OK, this will confirm a water valve issue. you will need to replace the water valve assembly in this case.

Click here for your new water valve assembly.

This is a leaking solonoid valve.
The valves are located just inside the machine where the water supply hoses attach.

• Remove the power plug
• Undo the top lid of the washer
• The valves will have some internal pipes clamped on their outlets. Remove the pipes.
• Dry the valve outlets with tissue.
• Turn on the water supply to the washer (if it was off)
• Watch the open valve outlets for seepage.

There may be between 1 and 3 valves depending on the model.
You should be able to replace the leaking valve quite easily.
