I have a 2015 Phaeton AH slowly leaking water from the 3-way valve when in the city water position. I have a new valve for replacement and was told by a tiffin rep that all I had to do was unscrew the two screws on the back bay wall holding the valve in place and the valve would be able to lower and easily replaced. Not so and it’s very difficult to work behind the wall. Would someone who has replaced the valve please assist as I don’t see a way to access behind the wall even if the wall is loosened.

I have no advice for you but interested in the responses you get as I would like to replace my valve also. Also, where did you purchase the valve?
Best of luck to you in changing out your valve!
Merry Christmas

I have a 2016 40 AP allegro bus..my fresh water tank fills up even when valve is in “City Water” position..and then begins to drip thru the overflow port outside.....I HAVE TO ASSUME..that the “City Water/ Tank Fill” valve is the culprit.. while I have not yet called Tiffin...it looks to me the only way to access this Valve is to remove the white painted metal showd covering these parts in the water/sewer bay? That is a lot of work to get to that valve in my view???

I am currently at an RV Prk in Gold Canyon, Arizona and will call Tiffin tomorrow (Monday, Dec 10, 2018) to find out becuase it has to be a valve issue??

Its got to be fixed!!

Before you go to the trouble of replacing the valve, here's something you can try that worked on our Allegro RED. Remove the valve handle and file about 1/8" from the stop area on the handle allowing it to close further. I did that with our RED and it stopped the filling. Also, if you have a shutoff valve in the line from the tank to the water pump, turn that off. Quite often it's the check valve in the pump leaking allowing water to backflow into the tank. That will let you know for sure it's the valve and not the pump leaking back.

My vote is for the pump check valve leaking....

Largeandy · 12-09-2018, 11:06 PM

Thank you Bob...I am betting you are correct! Thank you for the usefull advice..I will try your possible solutions...and the pump check valve makes a lot of sense...

Appreciate your comments and advice!!!

Lt. Dan

Thank you all for your advice. Will try your suggestions as I discovered that replacing the ball valve is a tedious test while working in cramped quarters. The white back panel when unscrewed only moves about 4 inches and to work behind the panel is tough.

Thanks again. Merry Christmas and Happy New Year to all.

Tried both closing valve from fresh tank to pump and “filing” 1/8th iff the valve handle.

Still getting slow leak to fresh water tank when valve in “city water” position. Leak is however slower so thinking it is the valve itself..may try to replace valve seat today and if that does not work I guess I have to take that darn white metal shroud off to replace the entire valve?? Dont know yet...

Valve seat can be unscrewed pretty easily from middle of face of the valve with an open end wrench.. if this woks... this will be lots easier than full valve replacement given it is hard to get to..

Will let you guys know the results and thanks very much to all of you. Nice to meet some decent and helpful folks online in todays uncivil society...

Thanks Guys...

My water tank was filling and overflowing when the valve was in the city position. As a quick fix I added a valve (on/off) from HD in series with the water line going to the tank. Easy to do with out removing the panel. When I'm on city water the valve is closed. When I need water in the tank I open it and switch the fill valve to tank fill. It works great I going leave it that way. I hope this helps..... Chuck

Hey CharleyL, would love to see a pic of how you have done this. I have tried all solutions herein, my 3 way valve still has a slow leak to the fresh water tank when in the "City Water" position. Curious as to where your HD valve was installed to accomplish your situation?

Thanks in advance CharleyL...hoping I can avoid the hassle of replacing that 3 way ball valve with all the work that is required to remove that white metal panel others have spoken about here...

Best
