Water Pumps & Holding Tanks

[Leroy Eckert]

If I understand it correctly all should be well with the possible exception of a failed check valve that should be attached to the air regulator. Theoretically, I guess, with the air regulator closed completely and a failed check valve, water would not get be able to flood the coach. One way to be certain, and it may be overkill, would be to plug both the purge air line from the switch to the regulator and plug the air inlet side of the regulator as it will never be used again due to the installation of the Schraeder valve. I also removed the old nylon air lines and replaced with 1/4" flared copper. I have found that my washer/dryer (curb side) which is plumbed into the curb side black tank keeps that tank very clean. It is backwards from my prints. Kitchen sink and shower (road side)go into the gray tank, and washer/dryer and bathroom sink and toilet to the black tank. This configuration also balances out the tank volume and usage. I have never had any real issues with the monitors either apparently because they remain clean. I will state one more time. For those who have an purge air system it would be prudent to perform a minor change to protect the aux air system from water flooding in the event of a check valve failure. If anyone needs real time info on this subject I am sure I am not out of line saying James Barone still has issues because his aux system flooded due to this very problem. I also think Bill Pape in MI has modified his and when he did found a very iffy check valve.

Now it can be purge it from a clean air source. More importantly there is no chance of water getting into the air systems. Just about have the water pump bay finished. It is re-plumbed and the new accumulator tank is in and charged to 25 psi. Just have to put the pumps in and hook them up. I mounted them to a separate sheet of 3/4 plywood so they could be easily remove to be serviced. I used reinforced vinyl tubing 210 psi to hook the pumps up to the rest of the system using Sea-Tech also known as Watts WaterPEX quick connect fittings. They can be used with PEX, CPVC, Copper and the dreaded Polybutalyne, you'll need the plastic insert with the Poly. Man are these puppies neat they just slip together and they will rotate so if your like me and once you've glued together the pipes and you miss calculated an angle, there is no problem. They come apart easily and will facilitate any future repairs. The drain pipe for the washer is on the curb side above the rear tank and crosses over to the front tank, into the top of the tank, but there is a second drain pipe next to it descending to the top of the Black tank. I'll have to do some investigating. It would be easier to put a T in the pipe and plumb from there instead of trying to go through the top of tank..
