Water pump problem - Keith Strehle - 03-07-2007 12:00
The water stops completely. Just for 30 seconds or so and the pump
starts again. I'm a little baffled by the 12 volt circuit breakers?
I have no idea what they look like? Wouldn't his normally be a fuse
protected circuit?

Ernie, is that the same as the expansion tank Pete mentioned. I do
remember fooling around with the schrader valve when I first got the
bus. I don't remember if I had the problem before that or not? I'm
going to pump some air ito it and see what happens.

Water pump problem - Pete Masterson - 03-07-2007 12:18
The circuit breakers (on my coach) look like little oblong metal
boxes with a little metal tab sticking out of a slot. I presume that
the tripped breaker will have the tab stick out more (so it can be
pushed in to reset). They are in the same fuse holders as the regular
fuses and have the same dual blade "plug" that goes in the fuse
socket like the regular fuses, although they're physically larger. I
have an electrical panel with a gazillion fuses and breakers behind a
panel on the front of the coach. (Open from outside.) and on a panel
in the back closet (over the engine) that's nearly inaccessible/
invisible. There may be another panel somewhere that I haven't seen/
found yet.
Circuit breakers are used on circuits that might be expected to have
brief overdraws where an automatic reset is desirable. It avoids
having a "normal" situation force having to replace a fuse
unnecessarily.
I note that some after market installations also include a fuse
holder with the appliance (e.g. the new variable speed pump I
recently installed). Those are usually fairly near the appliance in
an 'inline' fuse holder.

Haven't seen anything that fits that description? But there are some
small barrel shaped gadgets near the fuse panels. I'm gonna drag ou

Water pump problem - Ralph L. Fullenwider - 03-07-2007 12:44
Keith:
The c/b for the water pump is located in the left rear load center (drivers
side bedroom overhead cabinet. Should be a green wire (I think # 31)
Honestly sounds like an internal short in the pump motor, I just replaced
one of those my self doing much the same. If in fact it is the c/b tripping
and re setting.

Water pump problem - krminyl@... - 03-08-2007 05:53
If my memory serves me correctly, I think that tank is supposed to be
pressurized to something like 10-15lb only. I don't have mine anymore, but
there
is supposed to be a tag or label around the schraeder valve that gives the max
pressure it's supposed to have. I think 50 PSI is way high...

Thanks Ralph, I'll take a look for the circuit breaker this
weekend. Last night I pumped some air into the expansion tank, about
50lb. There was water in the expansion tank. I don't know but I'm
guessing that ain't good? However, the shower only stopped once,
rather that the normal 2 or 3 times.

Water pump problem - Pete Masterson - 03-08-2007 08:02
The accumulator tank is supposed to have about 1/2 water and 1/2 air
inside. The pump is supposed to pressurize the water against a rubber
diaphragm (water does not compress -- but the air compresses to
maintain the water pressure). If the air leaks out, then the tank
stops providing (sufficient) pressure to the water to make up for the
cycling of the pump. The diaphragm in the tank can (eventually)
degrade, requiring replacement of the tank. If water comes out of the
air valve, the diaphragm may have a leak. If there is air/water
contact (no diaphragm or leaking diaphragm) then the air will
eventually dissolve into the water, requiring the tank to be
'recharged' frequently.
Tanks come in a variety of sizes, but a replacement should be sized
approximately the same as the original. Using a larger tank will
simply require more pumping to bring up to pressure, potentially
overworking the pump. A too-small tank will run out of pressure too
soon, requiring the pump to run sooner-also overworking the pump.
Replacing the pump with a variable speed pump will allow elimination
of the accumulator tank.

Thanks Pete, I'll eventually upgrade to a variable speed pump. But
for right now it works (most of the time) and I'll concentrate on
stuff that does not work, like the microwave and the fridge. I
really do appreciate all the help.
