water pump *click*ing

I just installed a brand new shurflo pump in our 79 Itasca 25' and the first few times I ran it everything worked perfectly. Now, if I turn on the 'pump' switch at the panel and a faucet is open, everything is great. However if the 'pump' switch is in the 'on' position but the faucets are all closed, the pump will *click*, *click*, *click*... Why is it doing this all of a sudden?? Faucets won't pump water with the 'pump' switch off either. Pump is supposed to be auto..

When you say "click" do you mean the pump runs for a second and then goes off?

Does it stop after a while or continue no matter how long you leave it?

You may have a defective pressure switch (which is what tells the pump to turn on or off)

It will only pump water when the switch is on. Make sure there is no air in your hot water tank.

Make sure your outside faucet is turned off and not bypassing. Sounds like you might have a leak.

X2, a small leak will allow the pressure in the lines to drop, turning the pump on, which only runs for a second to build the pressure back up and turn itself off. That process will repeat over and over until the leak is found and repaired.

There's a check valve at/near the city water hook up that cause this pretty frequently, but if not there, the leak could be anywhere - including within the pump itself.

You still haven't answered my question about what you mean by "clicking".

Do you mean the pump comes on?

If it does not, where/what is "clicking"?

Its like every 4 to 6 seconds it will make a click or pop noise from the body of the pump itself. I tightened the kitchen faucet knobs really hard and it seemed to slow the increment of time between clicks. The sound would be like a circuit breaker tripping under a pillow

So the pump itself is not actually coming on- and a "pop" sounds electrical. I'm still going with a failing pressure control switch. You said its a new pump, so it should still be under warranty.

You can just replace the pump head, but that will probably cost as much as another pump. Pretty sure the switch itself is not replaceable.

I'm curious why you replaced the first pump.

Was it doing the same thing?

Try it with a slow stream of water out of a facet. If it "clicks" the same, but faster, that is the pump pressure switch going on and off rapidly. If it does sound the same, check all facets to make sure they are all off and the toilet is not trying to fill. If you have an outside shower in the wet bay, check it too. Very common problem.

That refrigerator light bothers me. Maybe the pump wiring behind the panel is shorted or partially shorted to the refrigerator wiring.

A little thought of me:
On the (new) pump there is a valve that prevents the backflow of the water.
Apparently it is not etirently blocking the backflow and therefore the pump goes on.
As it is just a little water pressure to build up the pump "runs" only for a part of a second.

Check your installation of the pump. (the thing is probably a ball and a spring, the equvalent of a diode in electronics).

This backflow thingy lives between the pump and the pressure switch.

The reason I replaced the first pump is that the housing had a crack in it. We hooked it up to city water and as soon as we turned on the hose the thing started spraying like crazy all into the cabinet. Like I said the new pump (ya hopefully its under warranty) did work just fine, just recently its started this thing its doing. There is a screw in the top of the pump that is + one direction and - the other, that I haven't messed with yet...

K I tried it and it did just what you described... i do not have an outside shower but i unscrewed the city water cap and the o ring wasn't seated quite right. I reseated the ring and tightened the crap out of the cap and that seemed to slow it quite a bit...
