Pump continues ..

Another newbie question for all you experts. We have a 2020 Jayco HT 30.5ckts and notice that after we flush or turn the water off, the pump will continue to come on in little burst about every 10 seconds or so. Some times for a short bit and then stops and sometimes it continues for awhile. Is this tell us about the water level perhaps…if not, what do you think. Thanks

If the pump cycles on/off, when your not using any water, then you have a small leak.

Start with the kis method. 1st place to look, is the cone at the city water connection. Remove it. Press on the plastic check valve. Reinstall the cone washer, withe cone facing out.

Next check all the treaded connections, there's not many. Stast with the sink faucets. Don't forget the outside showers. Also there a few that connects the water heater. You have at least one behind the water utility center. Also check the pump.

The pump has a check valve too. Sometimes they stick.

Check the plastic plug in your water heater for a small drip. That's one that is often overlooked.

Thanks for the suggestions… it only does it right after you use the tap or flush the toilet. If you shut the pump off and the turn it back on it doesn’t do it until you use the pump ( tsp or toilet). Sometimes it does it for a shot time and stops and sometimes it continues indefinitely. Thanks & take care

My pump does that sometimes, I have never found a leak and I suspect it is the pump's check valve passing some of the pressure back into the water tank. Interesting enough, on mine there are several pump switches, one near the entry door, one in the bathroom, and another at the exterior shower, in any case and because there are switches conveniently located, I rarely leave the pump switch on and instead I just turn the switch on whenever needed. ~CA

Check and see if both the hot and cold valves on your outside shower are OFF.

You may have air in the water lines somewhere, try "bleeding" off all the fixtures and any low point drains you may have and see if there is air anywhere.

Repair Water Pump For Less Than $10.

My SHURflo model 4008-101-A65 on demand water pump had been acting up. On my many trips to the bathroom in the middle of the night (old man bladder), I can hear the pump pulse intermittently after I return to bed since the pump is directly below me. This can go on for some time with just a single pulse now and then. I assumed it had a small leak somewhere and would cause the pressure to keep dropping but could never find one.

Well, the pump finally quit pumping (naturally right in the middle of a nightly visit to the pot). No more pump operation. Groan.

I decided to troubleshoot the pump. I ohmed out the control switch and indeed it was wide open. I believe this switch is somewhat underrated for the constant pulsing action that these pumps sometimes do when turned on to a low flow. After I removed the switch and exercised it a bit, I was able to measure resistive contacts which may have been causing my intermittent pulse.

The repair consisted of removing the switch block (3 screws) and popping the assembly open. I used a box cutter to pop it open. Very easy! Popped out the old switch and popped in the new one. A true no brainer.

You can order a complete switch housing assembly for twice the price but it is not needed as replacing the micro switch is a breeze.

Found a link to a repair YouTube (below) which worked great for me. For only $10 I got 2 new switches from Amazon, threw in one and kept the other. Easy peasy.

Here is a link to a YouTube repair video.
