Some plumbing contractors are using different types of materials to keep the price low.
Pre-insulated pipes with copper, steel, stainless steel inners and PVC, Gal, HDPE, PPE, Stainless steel outer. In-situ application of polyurethane.
Lets say you had a house built few of years ago Now you have a leak 99.6 % of the plumbers don’t know or have a way to patch, connect or fix these new types of plumbing pipes.
For example the old Standard water supplies are copper plumbing great stuff.
Now they are using CPVC a plastic water line. On the hot water side the maximum temp. Is 16° but if you water heater is set above that the pipes will burst.
The code requires 8′ of copper coming out of the hot ware side of the water heater.
And if the water heater is set at 18° and you are filling up a tub the CPVC will burst from 8′ from water heater to the tub smart move.
Also the max. straight run for CPVC is 40′, when CPVC heat up it expands actually grows in length putting stress on the fittings.
So with hot water and stress on the fittings this rate at the bottom of the list to be used in a house.
-A controversy regarding the use of polybutylene pipe (PB) raises concerns about its reliability and use.
The problem is the pipes often sprout leaks, to the dismay of many Arizonans who have the pipes installed in their homes and now face unwelcomed plumbing bills.
To many homeowners the onslaught of the problem is sudden and unexpected.
A plumber described the situation: “First you hear a bang, then there’s a sudden drop in water pressure.
Water then starts coming from pipes you didn’t know existed, causing soggy floors or holes in ceilings that are destructive and expensive to repair.”
Sufficient numbers of homeowners have shared this unnerving experience to provoke various lawsuits.
Consumer complaints in Texas prompted the largest class action in U.S. history against the manufacturers of PB. This action resulted in a $750 million settlement.
In Arizona, two lawsuits are pending in Maricopa County Superior Court to recover damages from PB manufacturers for Arizona homeowners with PB failure.
One of the cases is a class action suit similar to the one filed in Texas.
Average costs for PB-related home repairs are about $4,000.00.
How many other types of plumbing systems are going to fail?
