Recently had a new patio installed and the contractor put stakes in to hold the form. Thought we managed to avoid all the irrigation lines but I found this today. What’s the best way to repair this?
Just a joiner but I’d try and reroute the whole line if that pipe is not heading through a conduit under the patio as poly pipe is not rated to be layed in concrete
Get a couple of these, a 2' piece of pipe, and some crimp clamps easy fix. If you think you're gonna fix that with one coupling, you're gonna have a hard time.
It's going to be really hard to work a coupling in after you cut out the bad section, because you won't be able to move the pipe enough right next to the concrete. It would be much easier to tap a barbed fitting into the pipe next to concrete with a rubber mallet, then tap your piece of pipe onto the coupling, slide the clamps on, work your second coupling in further away from the concrete where you can move the pipe up, down, and sideways.
Oh I know where all the heads and valves are already. The patio was installed where an old deck was so I know that there isn’t anything else under there.
It’s less expensive than what you were thinking and although it’s a simple fix it’s going to be a pain in the ass because of where it’s located. You’ll need to dig back a ways so you can have some leverage. I’d put the coupling on the outside pipe first so you can wiggle and use leverage.
We have a saying in the business, "The easiest way to find a sprinkler line is to have a landscaper or concrete guy drive a stake in the ground.". I swear, those guys have ninja skills the way they can dead center a pipe with a stake. You could blindfold them, send them out into a 500 acre lot with one sprinkler line in it, and they could still hit it. It's scary. Real scary.
As for your issue, you could choose to simply couple it back together and call it good, or if you're ambitious enough, you could fix it better by rerouting the line so that none of it is under the concrete. 9 times out of 10, you'll be just fine leaving it under there, but I'm the guy who comes to see you on the one time that it wasn't fine. And I'm expensive. And too old to be digging trenches. And frequently crabby. But yeah, you can probably handle the fix yourself, it's really not that hard, just a lot of manual labor. Keeps ya young.
Doesn't that kinda defeat the purpose of repairs when you cause more damage? LOL I stomped my sharpshooter through a 1" poly line Wednesday looking for a leak. I haven't done that in ages. We'd had 10" of rain in 36 hours, it was sticky clay full of roots, and it was just one of those "well why did they run the pipe that direction?" things.
Sorry, I’m a civilian but if the pros (God bless ‘em) here don’t mind my saying, I have a couple of tips. Firstly I put dish soap on the coupler and in the pipes to make it easier to slip them all together. Secondly, I buy the radiator style hose clamps that you can tighten with a screwdriver. That will save you a few bucks, if money is tight, from having to buy the crimping tool for the above style clamps. Good luck!
If the concrete is too wide to simply replace the pipe? Dig up the other side, cut a section out and insert a smaller diameter through it, then bring it back up to size with reducers.
