Water Pump was: Re: LXi headlight surround/bumper

[Pete Masterson]

Rebuild kits are available for most of the water pumps -- you may
only need to clean the interior of the pump and replace the diaphragm.

Both my pumps were leaking badly -- and considering the amount of
work to remove, rebuild, and replace them I opted instead to replace
both pumps with a single variable (5.9 gpm) speed pump. It eliminates
the need for the pressure tank as well -- simplifying the plumbing
considerably. Several 'bird owners have made this modification, at
least one left the pressure tank in place which does reduce the
amount of cycling by the pump.

I've had the new pump in operation for more than 6 months and I'm
very satisfied with it. It provides a maximum 65 lbs of pressure,
giving much improved water flow, especially for a shower. It does use
up the fresh water tank a bit faster. (The Microphor toilet prefers a
max of 50 lbs pressure -- I plan to install a pressure limiter on the
water line to the Microphor in the near future.)

Can't directly address your toilet compressor -- but I have a
Microphor compressor just for the toilet. It's a 12 v compressor with
about a 4 gal pancake tank. It's set to a maximum of 90 psi and kicks
in at 60 psi. You might be able to find something similar that's not
OEM.

I do not have an auxiliary compressor for other air-powered systems
which is annoying for dumping the waste tanks when parked for long
periods. (I carry a "contractors" compressor for that purpose and to
top up the air in my tires.)

Brad,

I also removed the 2 shurflo's and the accumlator and installed
one Shurflo Extreme Series "Smart Sensor" 5.7 gpm pump and
am very satisfied. I agree with everything Pete said about it. The
installation is simple with water input/output and power; eliminating
the original rat's nest of plumbing is very satisfying. Plus, the pump
powers up on-demand - no more random water pump noise.
Turn the faucet on just a crack, and the pump makes a constant
whisper - no more cycling.

On the LXi, the Microphor toilet compressor is also used for the
slide seal. The compressor pump is stand-alone and is plumbed
into a 10 gallon storage tank. I replaced mine with an original
unit from BlueBird. I also installed a filter from Clippard, part
number MMFRS-3Q. The filter was installed on the storage tank
output. I find that my Microphor toilet pressure regulator works
better (lasts longer) if it gets clean air.

Pete and Dave,
Thanks for the info. I think Ryan at Mr. Olivers is planning to replace the A
pump and the microphor 12V compressor w/ identical units. Maybe not an
improvement but I like the idea of lower water pressure except when the better
half is taking a shower.
