What size piping did you need in connecting your accumulator.
Looks nice!

The existing factory installed flex hose is "Accuflex 1/2" cold water IAPMO 150 psi".

I couldn't find that exact hose at Home Depot, but I did find similar 1/2" i.d. (inner diameter) flexible reinforced water hose rated at 200 psi. It didn't have a brand name or markings at all on the hose itself.

I used the QEST * 1/2" Barb fittings supplied with the kit, plus a couple of SS hose clamps.

The tank itself is mounted w/only two screws. It's difficult to see in my pictures, but I used two #10 x 1" screws, sandwiching the tank flange above and below with 1/4" #6 neoprene rubber washers, topped with a SS washer at each screw head. These are lightly snugged down, in the hopes of preventing noise transmission through the tank flange to the floor.

I think someone also mentioned to check the pump screws, too. Mine were waaaay over-tightened, completely deforming and defeating the rubber bumpers that the pump is mounted to. These should be just tight enough to hold the pump in place, w/o squishing them down.

Hope that helps! Cheers,
-jd.

Wow! I sure would like to have the access to my water pump that you do. In the 30' Excella it's squeezed into the compartment underneath the closet floor along with the heater ductwork to the rear bedroom.

Jabsco accumulator lasted 2 months

I installed the Jabsco accumulator about 2 months ago and really liked the decrease in pump noise. But, on our recent 3 week trip it seemed like it was not working properly. I checked the air pressure in it and water came out the valve. Upon opening it up I found the inner bladder had torn.

The manufacturer was quick to replace it but it still meant we went 3 weeks without it. We could have used the power being sent to the pump since we were boondocking most of the time and nearly ran out of electricity.

I hope the replacement lasts longer.

Hey all,

The accumulators work well, but they do have problems like the bladders rupturing.

As an alternative, check out the new generation of quiet, variable speed water pumps from ShurFlo. They give you residential-like pressure and no buzzing or hammering. I've been putting a lot of these in the MoHo's I service, and have one waiting for me to install in my CCD.

I went a little overboard. . .

I put an accumulator and a VSD pump in my Tradewind. I even mounted the pump on special vibration isolation bushings.

The results were interesting. The accumulator will store 1/2 gal of water under pressure. When you open a tap, the water comes out very nicely, then you start to hear a gentle moan in the background as the pump spools up to speed.

It sounds like this:
. . . . bl . . . blip . . . . blip blip. . . . .blipitty blipitty blipitty blipitty blipittyblipittyblipittyblipittyblipittyblipittybl ip . . . blip blip . . .blip. . . . bl . . . .

It's very soothing.

I was gonna post some pictures, but I am evidently WAY OVER my picture limit.

Hey Lew, What do you suggest for the ShurFlo pump size and model for a 2007 Safari 27?

Thanks for all the excellent advice.

wj,

IIRC, they have a 4.2 gpm and a 5.7 gpm in their quiet series. I'll get the #'s, specifications and MSRP for you tomorrow.

Look No Tank...

i purchased yesterday a new:

ShurFlo Extreme Series Smart Sensor 4.0 to replace my prefectly good, loud, hammering water pump from the factory.
  • Flow of 4.0 GPM [15.14 Lpm]
  • Variable Speed Pump Controlled by Smart Sensor (trade mark sensor)
  • High Pressure @ 50 PSI No Pressure Switch Needed
  • Silent operation at any Flow/Pressure Condition
  • No Rapid Cycling
  • Seamless Heat Electro-Coated Motor Shell
  • 4 Chamber Design
  • Large Inlet and outlet Valve Passages
  • Automatic Voltage Protection
  • Current Limiting at 10 Amps Max.
purchased at RV Toy Outlet: price $160.99 tax $11.67 shipping $8.96 your price may vary as i'm lazy and didn't shop the part for price...

so i got that workin for me and you don't need a seperate accumulator tank.

Thanks Kev,

That's the pump that I was going to get the specs on for the thread. Mine is sitting in my fresh water bay, but is not connected yet. I've been replacing a lot of water pumps lately on big MoHos and these seem to be the favorite.

BTW, I could-a saved you some $$$$$ on that pump.
