Should I remove the accumulator?

The accumulator reduces the pump cycling on and off.
Leaving it in won't hurt anything.

Is not that blurb to hype the fact that a buyer need not spend extra money on an accumulator if they do not have one? Myself, I cannot imagine removing a pulse "shock absorber" to be of any benefit.

Well, I'll leave it in place and report back. :)

My 5er came with a 4008 water pump, and I ended up adding an accumulator tank, pipe insulation and flexible hoses to the system to help with the noise. The pump doesn't run anywhere near as smooth as the marketing would have you think. I'd definitely keep the tank.

I have had an accumulator downstream of my Shurflow pump for several years despite what they say. The one advantage of it is one can flush the toilet or turn on a faucet for a few seconds without the pump turning on since the accumulator furnishes the water. The bigger the accumulator the more water you can use without the pump.

Good news: I've installed the new pump and with the home made rubber boots, it runs absolutely silently. You have to have the cabinet open and your head down near it to hear it. Awesome! The old one was pretty quiet with the same boots, but not in the same league.


Bad news: The pump continues to run when it should have shut off. I'm still going through the system to ensure there are no leaks or air pockets. It's also leaking water out the front, which is dripping down from the power wire. If you look close at the image, you can see the water. :(

Accumulator today. Accumulator tomorrow. Accumulator forever!

The advertising blurb is saying that you can set the pump to let enough water leak back into the feed line so it won't stutter off and on while running. I would rather not have the pump pumping water back to the feed line.

TurnthePage, those boots look like diagonal slices of heavy rubber hose -- is that right?

(Please forgive me if I am coming in late on a discussion of the boots, but I did not see a post on that topic.)

That is exactly what they are. Similar to many shock mount systems in the navy.

I replaced an old Shurflo 3-chamber pump in my '91 Prowler 24C TT with a 4-chamber 4008 pump. I have to agree with Shurflo, the new pump does not need an accumulator. I have instant water pressure whenever I turn on a faucet. The pump is nearly silent, too, when running.
