I have a drinking water filter under the sink that has a very low flow rate.
This causes the pump to pulsate (cut in & out rapidly). The LEDs in the jayco are 12 volt (not multi voltage). They flicker when the pump is pulsating. One light has already failed. I turn the lights of now when using the filter. I believe it will eventually cause failure of the pump or pressure switch.
I have purchased a shurflo accumulator to overcome this problem.
The instructions say the water flow can go (1) through the accumulator, or (2) be T,ed into the system & blank the outlet of the accumulator.
The second option would far easier. If I go this way does the air have to be bled form the water side of the accumulator?
Keen to hear from anyone who has fitted an accumulator or has knowledge of any pitfalls fitting one.
Cheers Pete

Hi
it will not make much difference, any air in the water side will gradually be absorbed
The bladder should pretty well fill the space in the chamber, pushing out most of the air

I didn't think about that. The accumulator is precharged to 30 psi. You are correct.
Thanks Pete

Sounds like you might have an undersize wiring problem as well. Although the pump uses bigger amperage it shouldn't affect your lights that much, we had a similar problem & replaced our supply wiring with heavier gauge to overcome the voltage drop caused by the pump. The only thing that flickers the lights now is when the diesel heater is first turned on & that's only for a very short time.

I had the exact same problem, all I did was get a 1/2" plastic tap from bunnings and
placed it in the inlet line from the tank to the pump , I adjusted it back so as to restrict the flow to the pump
this slowed the flow enough for the pump to run Ok when you opened the filtered water tap

I've finally fitted the accumulator. With the 30 psi precharge the pump cut in pretty qiuckly. I dropped the pressure to 15 psi & now get approx 300 ml from the filter tap before the pump cuts in. Problem solved.

Hi Pete
15PSI is usually more than adequate for RV use
Saves battery energy if of grid.
Less risk of undetected leaks from connections under pressure
