Installing a new SureFlo water pump...

[Gregory OConnor]

One thing about pump ratings is the psi at a given gpm discharge.
shureflow seems to maintain sufficient psi at normal use. I fill the
fresh water tank and use the pump to pressurize the bus often while
camped with full hookups. Not hearing the pump run when all is quiet
indicates no leaks.

My 94 has two ShureFlow pumps I have the option of running both but
can only guess that that is to maintain a steady psi with higher
volumn flow. ( Like Ernie points out that is asking for a quick
depletion) I use one or the other to exersize both pumps
independently(choice is an "A-B-Both switch in the bathroom). One
thing to point out in this thread

The pumps have a built in backflow / checkvalve. that is; you can
not push water in the discharge side even with the pump off. if the
backflow craps out, pressurizing with city p.o.c. will send water
past the pump and overflow the Potable tank. If you remove a pump
for repair it is best to plug both lines (atleast the discharge) and
not loop them with a pipe splice.
