Thor water pump problem

[exit55]

Have a Thor 24.1 vegas 2016 motor home.
When you cut on spigot, Water pump is constantly starting and stopping. Cuts on instantly when you cut on spigot. Looks like it should run until you cut off spigot. Not. Constantly on and off. Is there a pressure differential or does pressure need to be changed? Thanks

When my fresh water is full the water pump will go on and off. When my fresh water tank is not full the water pump stays on until I turn off the water at the sink or shower.

Sounds like a couple of issues...

1) your pump may need a tune-up. Either a new diaphragm/bladder or a good cleaning of the bladder and the filters. Bladder/diaphragm replacement, if needed, is under $30 on Amazon. It’s a DIY job, just a little time and effort

2) You should consider adding (like many of us on this Forum have) an Accumulator Tank. It makes the pump run less & maintains a consistent pressure. Can be found for under $35 on Amazon & is a simple DIY job.

How hard is this to install? I have a low skill set. Does it come with everything you need? Thanks.
