Chris,
I installed a new ShurFlo pump and accumulator in our trailer during
our Winter sojurn, replacing the old Jabsco pump. Bottom line: I like it
a lot and feel that it was well worthwhile. The pump cycles less, even
though you can draw only about a cup of water before it goes 'on', and
the water pressure seems much steadier, making it nicer in the shower.
There is usually no cutoff valve on the inlet to the pump from the tank,
but MAY be a bypass valve after the pump. Its purpose is to allow
filling of the tank from the city water supply; if you leave it open,
there will be little or no pressure buildup, especially from the pump,
as it's just pushing the water back into the tank.
The accumlator and pump came from Camping World and totalled just over
$100.00, IIRC. Fittings came from the BroadWay Ace Hardware in McAllen,
TX, all connections were done with 1/2" reinforced tubing. That's the
stuff that's clear/transparent with some sort of criss-cross
threads/fibers in it.
