Microphor toilet and variable speed pump

[Pete Masterson]

A few weeks ago, I installed (as did several others) a variable speed
ShurFlo water pump to replace the (leaking) dual water pumps in my
coach. So far, I've been well satisfied ... but an unexpected issue
has come to light. We've found that the higher water pressure
available from the pump (65 lbs.) makes washing dishes and taking
showers more pleasant ... so even when parked where shore water is
available, we've tended to use the pump.

Recently, we noticed a problem with the Microphor toilet ... it was
not refilling after flushing and sometimes it would not flush
properly -- or you'd need to hold down the handle a very long time
for it to function as expected. After reviewing the troubleshooting
section of the Microphor documentation, I saw that the problems I was
having was due to "excess" water pressure. The Microphor is designed
to operate with 30 to 50 lbs of water pressure. If higher water
pressure is present, the very problems we were having may occur.

Others who have upgraded to a variable may want to take this into
consideration. Microphor suggests inserting a pressure limiter in the
water supply line to solve/avoid problems. (I just turned off the
pump -- we'll only turn it on for dishes and showers, now.)

Pete,

Thank you for the posting. Do you have the air operated Microphor toilet
in you coach?

Interesting...I was under the bed and found the water line strainer to
be cracked on the top, and dripping only a slight trace of water on the
floor. I change out the strainer and now the original water pump works a
lot better. I'm assuming the cracked strainer was sucking air. Can't
wait to install the variable speed ShurFlo water pump.

Yes, I have the air-operated Microphor (with a small 12v compressor
in the basement compartment nearby). It would be worthwhile to check
the Microphor website for the installation/troubleshooting manual for
your model. I may get around to installing a pressure controller for
the water supply to the toilet. I actually have a nice one in my
'junk' box from a long-dead drip irrigation system I once had.

Along with air regulators for the Microphor we all should put them on the air
line to the dump valves. According to Randy it would extend the valves life by
not pushing so hard when running with the air pressure is over 100 lbs. Just
another project I haven't gotten around too yet.

Dick,
Right you are. Our air dump valves are installed with the air regulators
per Randy. No problems so far. The black tank stinks...anything to do
with the air valves...Ha!!!

I don't think so, Curt. I use that white stuff I get at Quartzite and it works
great, no odor. I think it's called "Happy Camper". What did you use for air
regulators? And, did you put them in? Where?

My original post was about _water_ pressure. But the air pressure
issue is also an excellent point. As it happens, I have a Microphor
12v compressor that's independent from the coach air system. It's
limited to 90 psi. I plan to move my dump valves over to the
Microphor compressor when time allows as it will eliminate needing to
'air up' to dump.

I notice that the air-dump valves seem to work ok with about 70 psi
but are a little sluggish with less -- but I was in a very cold place
when I was taking note of the pressures (I'd pumped up the coach with
an external compressor since it wasn't worth the difficulty in
starting the engine in 25 degree weather...)

Dick,
I sent you photos showing the air regulators installed. I zip tied them
in place. Adjust them until the dump valve will open/close.

Thanks Curt. It looks like they are a common garden variety air regulator.
Should be readily available, maybe even at Harbor Freight.
