Hot Water Tank Leaking!!!

Hello Fellow Jayco Owners! Finally got our 2012 308 RETS set up on our permanent site and spent the last two weekends. Here's my issue.

The Hot Water Tank Relief Valve starts to leak (drips out of the valve) after it's been turned on (Electric) for a few hours. As a rule, we turn the hot water off after we're done using it.

Water starts coming out of the cover and down the side of the trailer. Not to mention it drips over some wires and the Propane Line for the hot water tank. I think the Relief Valve is bad or the Tank is getting too hot. If we use it and turn it off no problems, just when we leave it on for a period of time.

Any thoughts fellow Jayco Owners? As always, thanks so much for your help and advice..

John & Janine

Reintroduce an adequate air expansion pocket:
1. Turn water heater off.
2. Turn off water supply (city H2O or H2O pump)
3. Open closest hot H2O faucet in RV.
4. Open the P&T valve by pulling on handle at end of valve and allow H2O to flow until it stops.
5. Release handle on P&T valve it should snap shut. ( do this a couple of times as it may stick)
6. Close hot water faucet.
7. Turn on H2O supply Now that everything is closed the tank will refill and air expansion pocket will be re-established.
Repeat the above procedure if P&T valve continues to weep between heating cycles. If this is not successful then the P&T valve should be replaced.

When our house burnt we lived in my cousins' fiver for a few weeks until the insurance company had a house trailer brought in and set on the driveway for us. Anyway, he had never had any problems with the Pressure Relieve valve leaking, but when we started using the camper the valve was leaking. After talking with him we agreed that it should be replaced. I put a new valve in it. The new valve leaked as well. We put a pressure regulator on the water hose and solved the problem. When we moved into the new house (same water supply) we had a problem with all of the toilets in the house. They would shut off and then come back on 2 or 3 times. Had the plumber that did the install out. Turns out the water pressure regulator at the meter had gone bad. We were getting something like 150 PSI to the house. The water company came out and replaced their regulator and solved the issue. Turns out that is what was making the pressure valve on the camper leak and that is why when we put the regulator on the hose it stopped leaking.

That's why you should always use a pressure regulator on your tt.

Great point about the Pressure Regulator! There is one at the water supply which makes me wonder if it's bad. I can back the pressure down to see if it makes a difference.

As always, thanks for the great suggestions..

Yeah, but I was on my own property where the water pressure was never an issue until the regulator on our water main went bad. In this case our house was hooked to the same water supply as our house. Do you run a seperate pressure regulator on your house vs. what the water company puts on at the meter?

Most campgrounds have an anti-siphon device not pressure regulators. It's usually best to have your own pressure regulator to be sure.

The Campground where our permanent site is has what I believe to be a Pressure regulator on the supply line for our TT. Although it's much smaller than the one we bought at Camping World.

Now that makes me wonder if it is an anti-siphon device. I'll have to ask them this weekend what the valve actually is on their water supply line for our TT.

I can attached what I've bought to theirs as a precautionary or just not turn the water up all the way!

Thanks again everyone..
John

I would attach what you bought. Pressure is the same whether water is turned all the way up or halfway, only the GPM will be different. (gallons per minute)
