A brief article about waterproofing as told by a top contractor in New York City
In a solvent welded CPVC water supply system, it's a good idea to flush out the piping before pressurizing it. Flushing also expedites the curing of the solvent cement and helps to purge the system of tastes and odors. To do this, first close the ouse main shutoff valve. Then fully open all outlets, such as faucets. Go back and open the house main valve just enough to let water flor slowly into the new system. When wate reaches the lowest opening, it will begin flowing out there. Close this waterproofing valve off to a steady trickle. Move up through the house, closing each flowing outlet as you come to it. Let the water trickle from each for 10 minutes. This will carry away any solvent vapors left inside the system - the vapors actually dissolve in water and flow away. You may contact us anywhere in NYC at the number above.
