more water pressure
« on: May 14, 2010, 05:30:05 AM »
I have a question, we recently replaced all of out sewer lines in our house.  When doing that we had to replace a couple of the supply lines.  After we turned the water back on, I have really good water pressure in the back yard, but I hardly have any in the front now.  Do you have any suggestions on how to fix this?

U guys use 15/20mm alkathene for residential water mains?       Isnt that low density polyethylene? (LDPE)

I usually use and have always come across MDPE Blueline for a buildings water supply, or if its a dated older watermain HP Pvc, galv, or copper while doing maintenance work etc

I only see alkathene for garden sprinkler systems residentially or for farms rurally, stock trough water supplys etc, never seen for potable supply.
