For the third time my valve or whatever it is

?? is allowing the tank to fill on its own and over flowing.

Will have to get it fixed again, what am I possibly doing wrong ? Too much pressure at certain campgrounds ruining it ?

I have had high CG pressure blow by mine and overflow it. If you dont have a real pressure regulator like a Watts or Valterra (adjustable, with gauge) I suggest it. A particulate filter can also help, as stuff can get into the valve. I once had to open/close my valve several times under pressure to clear it out.

Is your diverter brass or one of the plastic ones? Should always use a pressure regulator, some campgrounds water pressure can exceed 100 psi, should be around 45-50 max going into your MH

Assuming you are referring to the 3-way valve that allows filling the onboard tank from city supply, you should turn off the water at the supply pedestal and relieve the pressure before switching the valve position. Also, it's possible the failing component is actually the check valve in the water pump.

That would be my first guess. I bought a standard 1/2" house style pressure regulator from HD or Lowe's. Don't recall which. I also placed a pressure gauge before and after the regulator. With this arrangement I know how much pressure is at the hose bib and what I am feeding to the coach. I have been using this arrangement for several years now. I never feed the coach more than 60psi. 50psi is a bit safer. My tank never self fills.

Too much pressure damages the check valve in the pump and it leaks back into the tank.
