P.S If the truth be known, work could probably buy one out of his petty cash jar!!!! Back home, we refer to that as "she money"....she don't need to know about "that money"!!!

SHE know where the jar is.....still on an allowance!

To be off topic: in a PEX manual I have, it says that a 100 ft length of PEX tubing has a lose of 5.8 psi at 2 gal per minutes of flow. At 3 gpm it increases to 12.2 psi. I read that as, higher pressure and flow at the hose bib could be a lose of pressure in the unit. As I don't have a single run much longer than 10-15 ft, the length wouldn't mean a noticeable lose at a fixture.

As a side note...it says a 90 degree elbow has the same lose as 9.4 ft of tubing.

A branch TEE = 10.4 ft__a TEE run = 2.4 ft and a coupling = 2 ft.

Considering the plumbing in my unit as an example, I could possibly expect to loose 2-3 psi between the inlet on the unit to any fixture. Not much all things considered. But the higher the flow and gallons per minute I can get from the fixture...the higher the loss. But who would notice?

I've read of some RVers adapting a common 2-litre soda bottle or a large diameter section of common PVC pipe thru use of a T fitting into the line to act as an accumulator - there's a wide variety of free/cheap containers to select from for this function - it doesn't need to be expensive...

Thanks Gary, You're right, just a tank would help, my Shurflo accumalator has the pressurized bladder which you can adjust from 20psi to 125psi. Shurflo suggest starting an air pressure setting the same as your water pressure from the pump and tweek from there. You check the air pressure with no water pressure on the system....Just FYI. rockin'

work, you are too much.......I love all this techincal goobledy-gook. Good info. I'll only add that the my rig with the Manabloc system has alot of water (Pex) pipe running thru it, which means lots of tees and 90* connectors. You got to remember everything has to go thru the Manablock. I guess I gotta alot of loss.....all in all the water system works pretty good. rockin'
