General Water question

[tigertom22]

I have determined that PO replaced the lines from sink faucet to water tank sometime after 2002. Which tells me this was working not too long ago. My question is - how would I test this?

The original water tank seems okay...and the pressurized water cap looks almost new...

Any tips are greatly appreciated!

Thanks!

If you have a pressure-feed-type system, and there is a valve for putting air pressure to it, this should be fairly simple. Put a tire pump or compressor to the valve, (be sure to set the air pressure down on the compressor, so as to not blow stuff apart with a 100-lb pressure setting!) then open the faucet. It should hold pressure and not leak air anywhere in the lines, and the faucet should not seep air either if the seals in it are good. You can check for slow leaks at the joints with soapy water and a spray bottle.

Air will leak like water would if there are any leaks, only without the damp mess....

Thanks. But where/how do i fill up the tank?

HI Tom,

I had been looking for a definitive answer and am not too sure this will help, but some of the workings of the pressure systems got discussed here:

In short, somewhere on the system, and I believe usually it was on or near the exterior fill, there should be what looks like a tire valve, where air can be pumped into the tank to pressure-feed the water through. You should be able to put air into it without water in the system, and it should hold pressure, or show up any leaks. Don't overdo it, 20 - 30 lbs should be plenty for testing.

so I finally tried to hook up the water line. Basically I don't even care about the tank I would juts like water when docked at a camp site. The water started going everywhere! So any reco as to best way to bypass tank and juts connect hose to sink, toilet, and shower?

Thanks!

Install a new inlet on the side of the trailer. Disconnect the tank and connect the new inlet line to the old tank supply line. Tank is bypassed. It may take some creative thinking to come up with the correct fittings. If you have an old copper line, the fitting is probably 3/8 flare....
