Drip, drip, drip

Filled fresh water tank. Turned on pump. Pressures up. Pump shuts off. A minute later pump comes on for five seconds and then shuts off. Noticed a constant drip coming out of city water hook-up connection. The check valve is welded to water hook-up. One suggestion is to cap city water connection. My question is where or what could cause the water to escape through this connection? Is this normal? I do not plan to use water tank, but to stay connected to city water at campground. If there is a leak some where, how do I find it? The supply to the toilet is turned off. Thanks for any and all help. Jack

Jack,
I would say if you cap the city water connection and your pump stops cycling, you've found the culprit. It is most likely the check valve at the city water connection. If after capping the city water the pump still cycles you need to keep looking for another leak.

Screw one of those little valves for hoses with the on /off lever to your city water inlet. As said above, most likely the check valve.
If this works you can make permanent repairs at your leisure

Added an external on/off valve. It worked! The pump only comes on when I open a faucet and then the pump shuts off. I did open the "new" on/off valve at the city water connection and a stream of water shot about twenty feet under pressure for about a second. Did not realize the pump keeps the entire system under pressure. Looks like I need to replace the check valve. Hope I don't do more harm than good using a welding torch. Thanks for the advice. Jack

Skamper,

That fix will work until winter. That valve is probably external to the temperature controlled part of the trailer. I would install a valve inside the trailer or replace the check valve.

Haven't fired up a torch yet. Old check valve is welded to city water hook-up. Will need to remove old to install a new one. Putting it on my long list of things to do. Last time I used a torch I nearly burned down my home! Jack

Huh?

Soldering copper pipes with a welding torch? Not within my skill levels. If this causes you concern go another route. Cut out a small section of pipe & install a check valve with compression fittings. This will make changing it out in the future much easier. You can leave the old valve in the loop as long as it's not leaking.

No need to solder copper when there are SharkBite fittings.

Very durable and super easy to install, even in very tight applications. They WILL solve your connection problems!
