Accumulator Tank

[PamlicoTraveler]

We just bought a new fresh water pump. I have always had an accumulator tank. With the tank of course the pump puts water under pressure so there's not a constant cycling. Do we need an accumulator tank or will the new pump be quiet enough not to need one?

The pump is a Shurflo Next Generation Aqua King Premium 4.0

I'm not real clear on what my plumbing system needs to be. Any guidance will be appreciated

PT, These particular pumps don't require an accumulator tank and by installing one you void the warranty, that is if you tell them. How quiet it will be depends on how you install it and to what. Most of the noise these new pumps generate comes from the vibration on whatever you mount it to. Chuck

Do you have a water heater? If you do you will need an accumulator tank to absorb the expansion in the system when the water heats up. My boat did not come with an expansion tank and if we took showers and did not use any water for awhile the pressure would reach 150 PSI and the pop off valve would release it. It would also build so much pressure the solenoids on the electric toilets could not over power it and would not open. I eventually installed two.

Well, now I'm confused.

Yes, we have a water heater. No electric toilets though, just manual. The accumulator tank is there and I guess I can just use it. I was wondering if we needed to.
