So the PO had modified the water system to permanently hook up to city water - I am not sure what he did or what he added but there is a pipe marked "drain" near the side of the cabinet with an extension on it and a stainless fitting that looks like a hose connection at the end - Could he have been filling through a drain? My book does not reference this drain and has two drains marked "lowpoint drains" near the knife valves and city valve. Although part of this "drain" is the same PVC as the rest of the system and the label "appears" to look like factory - picture below.
I have turned the 1/4 turn "city valve" horizontal and filled and drained tanks and black and grey tanks. So far I have operated on tank water and water pump.
Yesterday I hooked up a regulator with a pressure gauge on it, "closed" the city water valve so it isn't filling the tank and turned on the garden hose.
Water was spewing out of the sewer pipe with the knife valves closed - the pressure was in the "green" so I don't think it was over pressurized. I went inside to make sure water wasn't spraying around inside (LOL) and it wasn't. I opened the sink taps and water pressure was "higher" than pump but not like "house" pressure.
I left the taps on and went outside again and water was still "gushing" out of the sewer pipe. I then started worrying about overflowing the black or grey tanks so I shut the water off - I opened the knife valves and I can't remember but it seemed there was a lot of water built up in the grey tank.
I should note that I started with both tanks empty so the grey tank was filling fast.
Any ideas? Did I do something wrong or did the PO's mods likely have something to do with this?
For my maiden trip (starting tomorrow) I will fill and pump until after the trip and I can troubleshoot this further.
