The first pic is the T-valve, second is the bottom where it enters the PVC chamber, third and fourth are pics of the chamber side and top. It sounds like I need to install a pressure valve into the top of the PVC chamber in order to pressurize it. I'm still not clear on how/when this is done. I would think you would do this with the water pipes pressurized either by the pump or city water. If not, then how else will the chamber retain pressure as I'm pumping air in?That looks like a Water Pump Accumulator Tank, except it does not appear to have a schrader valve or rubber bladder. Here is a link to a pic of one at PPL: . Think I would send those pics to Foretravel and asking them. That only has the one tiny line going to it??? Does that top unscrew??? Quote Selected

Found them all!Couple questions.1. For the cold and hot water drains, where do they drain to? Back into the holding tank?On the ground under the coach. At least that is where it should drain to. They drain the lower water lines.I guess the better question is do they actually drain to the outside themselves or do I need to open the main holding tank drain in addition to opening these lines?

Does that top unscrew???Pat, I think the reason it may not have a schraeder valve is because this is what I rebuilt after the original one blew the top cap off and broke into about 10 pieces. The original probably had a valve, but I never saw it and rebuilt this before being part of this forum. Looks like I'll need to take it out and install a schraeder valve. Not sure how to prime it after that though. Quote Selected

Not sure how to prime it after that though.But you would need a rubber bladder for the air to go into. Applaud you for trying to build it, but think you would be further ahead buying one. You can get them at most any RV shop or probably cheaper at Home Depot or Lowes. Well, the bladder? See this Can a water pressure tank be repaired if the bladder no longer holds the air , but you are going to have to be adding air to it often. Quote Selected
Re: Plumbing issues Reply #29 – July 15, 2011, 04:19:57 pm Benjii, sorry I didn't reply sooner. We were at a FMCA Wisconsin Voyageurs rally in Marshfield, WI. (A rally is held somewhere every month up here. Great bunch of people)When I open the two drain valves under the couch in our 36' GV the water drains out under the coach right behind the driver's front wheel--right onto the exhaust pipe of the generator. No, you do not have to open the main tank drain to assist the two drains under the couch. Just open all the faucets, pop open the top valve on the water heater and remove the bottom nylon plug on the water heater (15/16" wrench) Quote Selected
Re: Plumbing issues Reply #30 – July 15, 2011, 06:26:13 pm Benji, you do not need to add a shraeder valve on the setup you have. You will not be able to build and hold pressure in a tank without a bladder. The air you put into the valve will just go on through to the water lines and that pressure will be lost when a faucet is opened. The air that is in the canister when the pump turns on will be compressed as the water enters the canister. That compressed air acts as a cushion doing the same thing as a bladder tank. A bladerless tank is just not as efficient and will probably fill up completely with water over time. When it does fill with water, it will become ineffective until you drain it. The only good a shraeder valve will do is let you purge the water out of the canister without draining the system when the canister becomes waterlogged . As previously suggested, get a bladder type accumulator tank or a get a new pump with a bypass that does not require a tank. In the interim the one you made will work until it fills with water.
