Water pump

[Curt Sprenger]

I've been out of town for a few day and probable missed some of this thread.

What I did is eliminate the OEM pressure regulator/check valve combo unit, installing only a check valve on the coach fill side, and using a 50psi pressure regulator on the outer end of the fill hose (should use one when hooked to shore water connection); this resolved all the tank fill issues that I have experienced. Yes, the sporlan valve may get plugged but so far only once in 3+ year. The problem was the OEM regulator was plugging up and stopping the water flow. I have pictures of the unit I built, maybe a write up. Email me if you need more.

I got a phone call from a member looking to bypass the electric tank

fill and install a fresh water tank fill port independent of the

sole shore water hookup. MarkD 1988pt40 said his tank takes forever

to fillup like there is a restriction some place. Curt and others

posted about this issue also. Then I remember Macy post the

term "Engineer" and realized there must be more to it.



I notice that tankfills on sob's are not dripless threaded on. I

wonder if this design is to keep the fill water hose pressure from

splitting the fresh water tank??????



I also wonder if the slow fresh water tank fill common with the

Wonderlodges is a design limit???? to keep the overflow above the

design limit of the input???????



I can see that with the 110 psi one inch meter at my yard I could

split a tank if the overfill could not keep up with the 30 gpm!!!

This is a consideration with modifying the fill setup

Actually the pump is pumping, just in a circle from the pump back to the tank.

One other thing to make sure it is clear how mine operates. If after filling the tank, turning off the water and disconnecting and storing the water hose you forget to place the fill switch in the off position, the pump will run and not pump water. I did that once and thought I had a bad pump until I figured it out. It made me feel a little dumb in front of the wife. She needed to use the head on the road.

being turned on open & close the sporlan valve or what control's the
valve?

I have never chased the plumbing down and do not have a schematic for that part of the water system.
Consensus is that the water goes in circles with the switch in the fill position and the pump switch on. In that case the water must be running through the sporlan valve and back toward the pressure regulator also which apparently has a check valve to prevent water from squirting out the side of the bus assuming the shore water is disconnected, because nothing pressurizes. Is this correct? If shore water is filling the tank and the pump is running the pump is fighting against incoming shore water???? As well there must be another check valve in the pump output line to prevent back flow through the pump while filling the tank with the pump switch off.?????
If so, no one has to be concerned with trashing a pump because it is always wet????? I have a Jabsco which can be run dry without any problems. Can a Surflo be run dry without issues?
Thanks in advance for the
info.
