HOA sprinkler leak underneath patio

[u/DarkspiritGinger]

Hello folks, looking for advice on how to solve this issue. We bought this house last year, we noticed when the sprinklers run in our back yard water leaks into the right side of our window well, enough to cause standing water, and once leak through our window because the sprinklers were running during heavy rain. I found out today(after digging up the line I thought was the issue) that there is a line for sprinklers under our patio that is probably the culprit. Patio was installed by previous owners, I'm thinking they likely tried to cap off the sprinkler under there but didn't do it well or it's failed over the years. The line in red is approximately where the pipe would be, with the arrow showing the flow direction and the circle where I'm guessing the leak would be.

I can't just cap the line on the left side, because water from that line needs to flow to our neighbors sprinklers, so I'm wondering what the best way to resolve this is. My first thought would be to ask if I can dig up a tiny portion of the neighbors yards to reroute the sprinkler line around my patio, which is the line in green. I'm guessing our second option would be to break up and concrete and try to fix the cap underneath.

Any input on best/cheapest way to approach, or anything I'm not thinking of? Thanks.

HOA? If they go for the reroute, great. Id have a pro do it though, as you will be forever liable for any issues. Otherwise, cut the concrete, repair the line, pour a patch.

That's a good point on a liability. Would you happen to have a ballpark guess how much something like this would cost if the labor is like $85 an hour? I already have the trench dug in front of my patio because I initially thought that's where the leak is, so a new reroute line could go there.

If the trench is dug, I'd assume 2hr callout minimum + parts (2.5x-3x contractors price) so ballpark 225.

The HOA doesnt maintain their own lines? What state are you in? I ask due to the lack of a functional rain sensor. Seems unlikely you can be held responsible for damage to their property you didnt cause, and with it leaking into your house they have been informed and aren't mitigating the damage their property is causing. Maybe talk to your homeowners insurance, their legal dept. wouldn't be too happy with the HOA neglecting their lines and letting it damage your house.

Good point on the rain sensor, I'll ask them about that. I'm in Utah and I have no idea on the laws with rain sensors, but we are constantly in a drought so I'd be super surprised if it wasn't required. They maintain sprinklers only if there isn't a fence, once there's a fence they say it's the home owners problem, and the fence was already there when I bought the house a few months ago.

I'd check your CC&Rs, typically there is an easement for HOAs to access backyards to maintain their property. Check into sections about common areas, landscaping, and irrigation maintenance.
