Testing latteral

I am currently helping out on a project that has a few drainage issues. Water is getting inside the building's crawl space. There is 2 spray zones near the building. They just put some tile next to the foundation and drained that into 33 gallon drainage basin.

Ran the 2 zones of sprays for 15 mins each and the basin was full of water within a hour. The guy in charge is convinced that the 2 zones are leaking underground somewhere so he wants me to test the latterals to see if they are leaking.............it is a 13 year old system with drains.

So next week I am going to pressure test the zone. Any thoughts about what would be a acceptable amount of loss in the zone pressure over time??

Probably something simple. Verifying and confirming are your most important tools.

Turn off all your sprays or cap heads and utilize your water meter. An acceptable range of water loss should be less then a gpm with all the heads off as much as possible . If the flow is higher then you probably have a leaky fitting such as a marlex.

It's probably all vans and 15 min on a shrub zone around a building will no doubt flood the area. Change out nozzles and implement a cycle soak schedule

No need to over think this just yet. Keep it simple for now

Good solid advice Mitchell.

I agree with Mitch. While it may appear to be a leak, it could be something as simple as improper management.

He did say "with drains". Won't all the lines drain out like they're supposed to after the zone shuts off? That could be a lot of water, depending on the layout of the zone.

Or as simple as a missing or broken head..an older systems which have not been regularly maintained could have buried heads ...a missing nozzle on a buried head could put out lots of water...

When the heads are plugged, turned off, capped or whatever, the inrush of water can be counted at the meter along with any loss from leaks.

Verify first, i have seen many leak jobs that aren't leaks at all.

Treat the disease, not the symptoms.
