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?

replace all water pipes underfground to the toby (valve on the street) in 15 or 20mm alkathene

I wouldnt use 15mm alkethene, rather 20mm

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.

ldpe sweetas for most water mains - pressure rated to 600kPa?

whatever product needs to suit intended purpose




I have come across :

galv
ldpe
mdpe
hdpe
various classes pressure
bute (yes bute)
copper

there are still many places/councils using 15mm ldpe for civic/supply side of toby
