water pump?
The water pump seems to run constantly in our '14 Cougar... 15 minutes before I shut it off.
Any ideas why?

Also assuming you are aware that the water pump is not necessary to be ON if you are connected to CITY WATER. The city water will pressure up your water system.
I only use my on-board water pump to pressure up my water system when I have water in the fresh water tank. My water pump inlet has no connection to the city water connection.
I leave my WATER PUMP switch in the OFF position unless I am off the power grid and have water in my fresh water tank.
This is a simplified drawing of a typical water flow setup...

Quick point of clarification, since I haven't had mine apart (yet. I'm sure that day is coming, too). I've always thought the check valve for the water tank feed was on the pressure side of the pump, not the intake. Am I wrong about that? Thanks.- There are some variations on how different units are plumbed, but here are some things to look at.
If your pump has a plastic bowl type filter on it, check it for cracks. The water heater relief valve could be leaking. The city water connection could be leaking. laidback wrote:

Check to make sure your winterizing valve is turned off, if it is left open your get exactley the symptoms you are describing.- Also assuming you are aware that the water pump is not necessary to be ON if you are connected to CITY WATER. The city water will pressure up your water system.

Roy Ken - Faulty pressure switch?
- Water pump running constantly.........
Sufficient water level in fresh water tank?
Air leak on suction side of water pump?
Didn't open faucet and purge air out of system?
Water heater filling?
Open low point drain valve?
Water leaking thru city water connection check valve?
Pressure Relief Valve leaking thru?
Toilet water valve leaking thru?
If you have a 'water panel' fill valve in wrong position..water pump just recirculating water from tank thru fill valve back to tank?
Bad pump? - Yeah....spits like crazy, I bet its air

If left on mine will run for just a second about once every 20 minutes. Always suspected a leak but can't find a thing. I assume it must be air????
Hope you figure yours out as well.
Those pumps have a built in check valve that sometimes gets something in it. Try taking it apart and cleaning it or sometimes you need a check valve repair kit.
Shurflo pump check valve- If left on mine will run for just a second about once every 20 minutes. Always suspected a leak but can't find a thing. I assume it must be air????
Hope you figure yours out as well. - A few things I can think of.
Do all the faucets work without spitting out a bunch of air? I've seen a big air bubble in the lines keep a pump running.
Is there a leak in the plumbing? I would think after 15 minutes of constant running the leak would be obvious though.
