Water Pump Runs Continuously

[craftsman]

Just discovered my water pump is running continuously. This must have just started because I was in it just yesterday and it wasn't running. Also turned on the water and the pressure seems a little low. Any ideas as to what would cause this?

Make sure you have water in the fresh water tank. If so, then look for a broken hose. Pump will stop when it has back pressure. Without water it will not turn off.

Also if the pump has water and still won't turn off, it could be bad. Depending on what type of pump you have, they are either a series of diaphrams or a single diaphram if it is the older type, and they all have check valves internally. If the check valves start leaking, or a diaphram fails, they will run continously.

Thanks guys. May be time for a new pump.

I see you have a newer trailer. Don't know about the new pumps, but you could by parts to repair the older ones. Might be worth a call to a dealer, as they are easy to work on.

Unless you have freeze damage, I'd be surprised if your 2007 already needs a new pump. You may have an intake problem like I'm presently having with mine. A fitting on the intake side of your pump may have a crack or even the hose itself. It may also be as simple as tightening down a clamp to ensure an airtight fit.

We developed a leak under the bathroom sink between the back of the cabinet and inner skin. A connection on the outside manifold/one way valve was cross threaded, road vibration probably loosened it and it started to leak.
I noticed water dripping outside behind the roadside rear axle.
It was the rear plastic thumbnail fitting you see in the photo. Was able to stop the leak by un-screwing, coating the threads with two part construction adheasive and re-connecting.
