Re: any experiences with Seaflo pump?

Reviving this old thread because I want to STRONGLY recommend the Shurflo 4008 discussed here earlier.  I have completed the installation of our new pump, and I could not be any happier with the result.  A few details follow, for those interested.

We originally had a Shurflo 2088 installed by PO about 5 years ago.  It was still working.  We also had a 2 gallon blue accumulator tank mounted on the top of the water pump bay, which made working on the pump almost impossible.  My goal in replacing the older pump was to take advantage of the newer "bypass" design, and (hopefully) simplify the pump bay plumbing by removing the accumulator.

My installation went very smoothly.  Removed the accumulator tank, then the 2088 pump.  Decided to clean up the plumbing a bit.  I had 3 drain valves in that bay: fresh water, hot water, and cold water.  Each one had a 1/2" pipe sticking through the bottom of the coach.  I was never crazy about that setup, so decided to simplify.  I removed the old brass hot and cold water drain valves, and replaced them with new push-on plastic valves.  Since we never "winterize", they will get very little use.  I also removed the old brass fresh water drain valve, and installed a plastic valve there.  The hot and cold drain lines were combined into a 1/2" CPVC manifold, routed across the front of the bay, and merged using a "T" with the fresh water drain line.  The "T" has a 1/2" pipe pointed down through the coach bottom.  This allows all 3 lines to drain out one hole, and eliminates the need for the other two.  I covered the 2 un-needed holes with aluminum plates, top and bottom, sealed with calking compound.

With the accumulator out of the way, the 4008 pump could be mounted further toward the front of the compartment, making for easier access.  I installed brass SharkBite ball valves on the pump inlet and outlet pipes, as suggested by Barry in a earlier post.  I also installed the Shurflo pre-pump strainer and the "Silencing Kit" mentioned earlier in this thread.  The whole installation now looks much neater.  I cut off and capped the original line going to the accumulator with a SharkBite termination fitting.

Refilled the water tank, and tested the pump.  The improvement over the old 2088 is nothing short of amazing!  The silence is deafening!  Where the old pump could be heard everywhere inside the coach, there is NOTHING heard when the new pump runs.  Even sitting outside, with the pump bay door open, and my head 12" from the pump, I can just barely hear the motor.  ALSO, there is nearly zero vibration, even with my hand on the pump.  Only a almost imperceptible hum is heard (and felt) when touching the pump.  I wonder if the "silencing kit" hoses are even necessary with this pump...but since I already paid for them I will leave them in place.

Besides being QUIET, the pump works great.  Water pressure is much improved, especially in the shower.  The pump simply delivers whatever is required, from dribble to faucet full open, automatically and seemingly without effort.  I see no reason to use a accumulator with this pump.

I love it when a upgrade or mod is 100% successful on all counts.  I will have to say this 4008 upgrade totally meets that goal.  ^.^d

Chuck,  neat neat neat plumbing bay.  Like that the water pump head end faces out and can easily be adjusted if ever you want to tweak the bypass & pressure switch (which should never need to be done).  The flexible in & out hose also help by not having critically located hard pipe connections to line up to pump.  Great that the Shurflo 4008 is doing the water flow job for you.  Thanks for the summary.

FYI, we later installed the small Shurflo plastic accumulator with same 1/2" connections as our 4008 pump and with one additional flexible hose put the new accumulator on the output side and it seemed to help a little at very low water flows.  The accumulator is not a game changer, but it did not hurt either.  We did not mount the accumulator.
