Static vs Residual on a rural waterline extension
Static vs Residual on a rural waterline extension
(OP)
Readings at two local fire hydrants on a 4" line, so we are a ways from the reservior, but what else might cause the vast difference in static vs residual psi at the main line.
Static 190 psi
Residual 20 psi
Flow rate 100gpn
Re-ran the test and got the same results. I need to serve 6 homes the farthest being 800 feet away and 100' higher than the connection point. Does someone have a recommendation on what type of booster pump to use/cost of it?
Thanks in adv.

Your should ascertain the root of the problem prior to use of the water main.

I havn't done a lot of water line extensions, but have never seen a residual pressure test vary so much from the static prssure...

RE: Static vs Residual on a rural waterline extension
length of the watermain from the water source to your hydrant
size of the watermain
any other waterlines parallel to your main?
is the source a tank or a pump?
if a pump, see what the capacity is
how old is the waterline and what type of pipe?
how many service connections between the tank and your hydrant?
The review may lead you to the conclusion that the pressure test was accurate. If not then redo the test and be there when it is done.
