I added an accumulator tank, about $50.00 thru Amazon.  Because water doesn't compress the pump comes on any time there is a pressure drop, the tank basically has captive air for the pump to push against and store a little water so the pump doesn't cycle every time you crack a faucet.

Yes, it will cycle on and off quickly if you don't have the faucet open all the way.

You can buy an accumulator tank for a camper but I don't know how well they work.

The pump is pressure-sensitive and turns on when it senses lowered pressure.  Your public water supply has constant pressure and if you have a private well, there is usually an accumulator tank which helps store water and water pressure.  Because your Pod's pipes and faucet(s) are directly connected to its water tank, the pump has to run essentially every time you turn on a faucet and pressure drops.
An accumulator tank would help even out pump runs but there usually is no space available for a tank large enough to help.

Thks for the response, something strange, when the faucet is open at 2/3 the pump cycle often like each second.

Yes, working like it should.  What you'll need to listen for, for example, is if no water has been turned on and you hear the pump come on.  That means you're loosing pressure due to a leak and would need to track that down.

Also agree.  The pump will supply water "on demand".  As it sees a drop in pressure, it will turn on - off when it sees high pressure.  There are some modifications to help reduce the pump noise but, none that will completely eliminate it.

I agree, all 3 things are normal.

Hi everyone,

It's hard to explain in english, how do i know that a water pump is working fine. I'm able to have water if i fully open the faucet and the water pump run all the time and i can heard the water pump working. If i open the faucet just a little the water pump run every 2 or 3 second and during 1 second.

So,

1- is it normal to clearly hear the water pump when it works?
2- is it normal the water pump run all the time when a faucet is full open?
3-is it normal it stop and start when i open the faucet just a little and i can see the water flow changing with the restart of the pump

Many thanks for your help
