Macerator Hose Pressurizing???

I know that I have a water bypass issue in one of the water valves as my 12v water pump cycles about every 45 seconds.

But what I donít understand is how my Macerator Hose is filling with water which in turn (caps on) will pressurize the the hose, which will pressurize the Macerator Pump which will then begin to leak, filling the water bay and then leaking out.

I am clueless how this can happen. Help!

Sounds like you left the grey or black dump valve open. I have done this before but nothing leaked.

You've got a leaking grey or black tank valve. With the SaniCon connected to the 3" discharge, you won't notice a leak, but if you had it capped off, every time you remove the drain cap, you would have build up, behind the cap. The leak is going through the bypass and filling the hose.

Easy to check, remove the SaniCon 3" hose, close the valves and leave a drip pan under the 3" discharge.
