The 5.7 gpm variable speed pump produces about 65 psi. The pipes in most RVs should be able to handle this without serious problems. I experienced zero problems (other than a glitch with the Microphor flushing -- but that wasn't the pipes...)

If you are very concerned, Shurflo also makes a 4.0 gpm variable speed pump that produces about 50 psi.

Shore water is limited to 40 psi by the most common limiting devices -- and is a very conservative setting. Adjustable pressure limiters are available that allow higher pressures. (Many BBs have 'built in' pressure limiters located at the water input port.)

Visit the Shurflo web site for information about both the 5.7 and the 4.0 gpm pumps:

I just replaced ours with a Shurflo 2.8 GPM because I was concerned about water pressure in the older coaches. Wouldn't a higher flow rate pump potentially develop a higher pressure than the ratings of our old pipes and tubes?

Hi Ron,

I've been there enough times to prompt me to rip out the two shurflo's
with accumulator tank and replace the whole contraption with one shurflo
extreme 5.7 gpm constant pressure pump. No looking back. :-)

We had Foretravel of Nacogdoches replace both of our waterpumps last April. They worked fine up until sometime last week. The wife commented that she thought that she had been hearing the water pumps running continuously for several minutes. Oh oh, I thought, empty water tank and a faucet running somewhere; maybe a leak? Nope. Tank is full and faucets all secure. No leaks anywhere. Cycled all of the pump switches on/off. The pump would turn on/off but no suction, no increase in water pressure. Crawled into the pump area to do a visual/feel. Only the top one runs but no suction. The bottom one won't even run. Anyone been there? Thanks.
