PVC cement designed for irrigation systems:

Yes, it is glued like PVC piping but, it is not flexable like a usual irrigation black piping.
It is a rigid pipe so cutting out the damaged section and trying to place a new piece in is extremely difficult. I watched Massey do a repair on my damaged line. They had a rigid piece of pipe that telescoped longer when put in place and glued the ends in place to the existing rigid lines. I guess if you dig a big enough hole really big you might be able to move the piping to install a standard pvc pipe and 2 couplings.
good luck

Thanks. Yes it will - I've always felt, since purchase, that there were inefficiencies with this system, obvious lack of maintenance and no modifications post new add on landscaping since build date.

I found several grown over spray heads... among other issues over the last year. The project is warranted and overdue....and its huge. But then....I'm retired!!

Ace advised using the flex pipe for repair....when I thought it was a pvc pipe. I thought about it for a day then decided I didn't want to mix mediums. Did a little research and came up with the 4 90's solution. You cut the bad section out - put a 90 on each cut end, come out of the 90's with a short riser - add 2 90's and a cross piece and there it is. I'm a bit embarrassed that I didn't come up with that on my own - its an easy solution to repairing "fixed" underground irrigation piping.


The result is not a straight line but it doesn't matter given the amount of water pressure running thru the pipe. I like the 4 90's cause it keeps it in the same medium family.

I need to know that the repair will be long term without any doubts. When I fill in that hole I don't ever want to re-visit it again. Peace of mind goes a long way towards easy sleeping.

For sure - with that dime size hole I'm surprised that the sprayers on that branch continued to spray all this time.

I'll be leveling/replacing every spray head and that is going to open up a ton of opportunity for sand getting into the system....

Thanks for that!

Flex PVC pipe.

Interesting - will check that out. Thanks!

Here is a good source for sprinkler heads. And, it's nice to have extras. Congrats and Good Luck with your project.

Rain Bird Sprinklers

Flex PVC is a perfectly good solution, 1/2" or 3/4" whichever is required. The same material you probably have at every elbow that rises up to a sprinkler head. PVC pipe cement glues it just as securely as rigid PVC pipe.

Nice project. I’d highly recommend you switch to a smart irrigation controller if you haven’t. We love the Rachio which updates schedules based on weather and is also available with a leak detector.

You surly love green grass! 👍

Come to Hammock at Fenney .. miles being installed and experienced professional people making the installations ..

I had a soggy planter area that no one could figure out what was wrong until I dug deeper and found the pink pipe also with 2 gash marks in a new home. The builder sent out people to fix it so was lucky. There must be a lot of careless installation with landscape plumbing.

Make sure there are no stones, rocks or other debris touching the pipes.
I had to replace a section that was resting on a rock about the size of a baseball.
It eventually wore a hole in it.
Good luck with your endeavor..
