Our water pump.

[jimbo21793]

It goes on for about a second every 2-3 hours. Just a short small brrrrr. Then it’s over. Any ideas as to why this is happening?
Thanks

Has to be a leak somewhere I would guess. I'm sure you've looked for that so maybe a job for the dealer. Maybe try a pressure test.

The leak could be internal as in back leaking check valve.

How about a leak into the black or grey tank. Is that possible? Is there any water under the unit?

If you had a leak, you would see it somewhere. Ours did it too until I put in the accumulator tank. Seemed to make it go away.

Outdoor shower may be slightly open.

Did you find the leak?

It does not have to be a leak. You could be losing pressure back through the pump due to faulty check valve.

My experience is that the check valve for the pump has debris in it. First unscrew the cover on the filter and clean the screen. Next clean out the check valve. You can also order a check valve kit to rebuild it if it is worn.
