I'm trying to cut down on the constant pump cycling in my MH. Does anyone have the small 9"X4" Shurflo accumulator? Does it reduce water pump cycling substantially, or should I install a larger model? I have the Shurflo 2.8gpm pump.

Yep - it will slowdown the cycling - have one on the 5th and boat. Bigger unit will cycle less - but think about how you winterize!

I have a 1 gal accumulator from Home Depot, works the same but bigger. The larger tank WILL reduce cycling, but the run time of the pump will be longer each time it runs, as it has to refill the tank.

I can get 3-4 flushes of the toilet before the pump recycles (the DW gets 2).

It will also reduce the pulsations of the pump when running by quite a bit. The larger tank will add increased the time between pump cycles. Once installed, you'll never go back to a rig without one.

As for winterizing, once pressure is bled, the bladder allows any water inside the tank that freezes to expand, .. I never had a problem with freezing.

My last two RV's had pumps that pulsated if I didn't have the faucets all the way open. The reason for this is the water restrictors in the faucets. I removed these restrictors and adjusted the pressure switch on the pump and they continuously ran even with the faucet slightly open so there was no longer pulsating water coming out of the faucets.
Steady flow at any rate.

I agree with the above, and I'd rather get a Home Depot one or one from Amazon or Ebay instead. Get a minimum of 1 gal size, no more than 2 gal and make sure its for potable fresh water, not for hydronic heating. I saw a 2 gal on Amazon for $22 plus 13 shipping.

I installed a 2 gal. accumulator from Lowes to smooth out my pump's operation. I have a valve installed in front of it that I can shut off after draining it for winterizing. That prevents the pink stuff from getting in the tank where it would be more difficult to rinse out.

Hi,

I installed the small Shurflow accumulator and was very happy with it. Later I installed a 2 gallon tank, it is a little large, but also works well. The disadvantage to such a large tank is it takes a little while to pressurize.

The shurflow tank also makes the pump almost silent! It used to sound like a marching band when I would take a low flow shower, now it goes on and off for about 10 seconds.

Well now I use a variable speed pump that speeds up to pressurize the larger tank, and then slowly runs to keep the pressure at around 55 PSI. Yes I get a great shower with all that pressure.

Good Luck,

Fred.

The question is poorly worded

if the pump currntly runs 20 times a day totallying one hour

Then with the accumulator it will still run one hour.. Just not 20 times a day (perhaps only 5 or 15)

I installed a 1 1/2 gal bladder type accumulator (kind used for sprinkling pumps) purchased from Lowes. Manufacturer said to fill the bladder to 2 psi below pump cut in pressure which in my case was 25 psi.
Used a galvanized 90 deg. street elbow out the bottom of the tank to which I welded a piece of angle iron with a couple of holes drilled for mounting. Get approx. 10 flushes or about a gallon of water out of the tap before the pump runs. Takes about 15 sec. of pump run to refill the accumulator tank. One of the best upgrades I've done. KDK

Just how often does your pump cycle?

Does it cycle when you are not drawing water?

You could have a slow leak or air getting into the inlet side causing a lot of cycling.

If no mechanical problems then the accumulator will help with the cycling.
