Woke up to a water alarm going off

September 08, 2021, 09:36:07 am

From the advice on here, I picked up a half dozen water alarms. I had put one on the floor of the water pump/pressure tank, this is the one that was going off at 6:30AM today. Sure enough, there was a small amount of water on the floor, you can see it in the photo. These alarms work!

I am at a campground and the current setup is the campground spigot is connected to a hose that is connected to a water filter which has a water regulator on the out side, then it is connected to the coach's hose. The spigot is open while we are here.  We use this setup at the house and have not had any problems.

It appears the leak is coming from the hose from the pump to the tank. My current thought is
 1) the change in temp caused the hose to shrink, and the clamp has loosened. Going from mid high 90s-100s to mid-upper 30s
 2) the water pressure allowed a higher pressure. I am dubious of this since we use the same setup at the house for 3 weeks with no problems.

I am draining the fresh water tank currently and will see if it continues to leak. It should stop since it is not related to the city connection.

In order to fix this, do I need to remote the entire unit, meaning tank and pump? It sits on a black platform. And of course the connections are facing rearward so I cannot see what is happening. The unite is a Flojet 2840. I did take a pic of the place where I see drips.

Edit- tank drained and it is still leaking with the city water connection on. I turned the city off

You can't fix a leak until you can get at it.  Might need to remove the blue bladder tank to get some working room.  Once you can see clearly which connection is leaking, then take corrective action.

If it is a threaded connection, might need a new sealing washer.

If it is a crimped connection on the water pipe, it might be possible to use a tool to tighten the crimp...but I doubt that will work.

You can replace a failed crimped connection with a SharkBite push-on connector.  Usually find them at Lowes or Home Depot.

Consider not running directly off of the spigot. Most here fill the water tank and use the water pump all the time. Less chance of big leaks this way, especially important if you are away fro the coach.  Shut the water pump off when you are away from the coach. We shut ours off at night.

I think I found it. I was able to remove the 4 screws holding the black platform, then jumper the pump while pouring water into the inlet. It's leaking at the outlet of the pump going to the pressure tank. I undid the clip on the pump side, unbolted the tank and removed the tank/hose line. There is an O-ring where the hose and pump meet. The temp change would cause this to expand/contract. Now to find an O-ring!!

Leaving the shore water connected is inviting disaster. Does the pressure regulator work? Maybe yes, maybe no. Aside from driving on treated roads in winter, leaks from shore water being left on are probably number two in bulkhead/sub-frame damage.

If your arrow marking the drip is showing it at the locking tab for line into pump it might just be that the O ring on that connction needs replacing.
This is a simple fix. Close the line valve before the pump and undo the opposite water line on out side of pump (after opening the valves for hot and cold low points that are by pump. Disconnect tge 12v wire and remove the screws holding pump bse in place and lift assembly out. Replace both O  rings and use a bit of silicone grease on them and re install.
While pump is out check the fittings for cracks as well, just in case.

Funny we both wrote comment at same time.
Make sure you get the correct cross section diameter o ring as this is very important
