Ok for PVC to remain under pressure?
putting in a sprinkler system and another hose bib. Using 1" pvc and woke up this morning with a fear that pvc under constant pressure (90psi) is a broken pipe just looking for an early reason to show up.
was my dream just that or is there any reason to be concerned?
If the pipe is rated for the pressure and installed correctly, I wouldn't worry TOO much. :)
If you used schedule 40 PVC....it's rated for about 270 PSI.
Here is a chart showing the pressures for schedule 40 and 80
PVC is great for sprinklers....and yes, I ran PVC from my house to my garage for the back yard water hose.....
BUT....I went to great lengths to make sure the PVC is protected from damage.....PVC will not tollerate impact damage as well as copper will....hence, I would not use it in a area where I know my kids would run into it.....
As long as it's protected....your fine.....I assume you have a ball valve in front of it so you can shut it off if there is an issue?
Some people use the thin wall PVC for irrigation. It will not take abuse if left exposed
Yeah, I'm using sched 40 and it says 450 psi so I figure I'm safe there. And yes, priming and gluing deburred joints.
I did put a ball Valve but a good portion is going to be under concrete so my fear was after 3 years of continual pressure I was going to get a leak under my driveway/sidewalk.
Thanks for the help!
