Water main leak?

Use a probing rod to locate line in the wet spot.
Dig up and expose line.
Turn water back on and see what direction the water is flowing.
Keep digging till you find the leak.

Yep, you can do this. Or, you can call a plumber who does leak detection and pay out the arse to have them locate the leak. Short runs on a supply line and noticeable leaks (as you seem to have) you can do yourself. We have two different long runs on the main supply line. We had a small leak that would have been a pain to try to locate. Paying the plumber to find it was worth every penny.

I had a wet spot in the yard and was sure the leak was in the supply line from the meter. It turned out to be under the slab far away from the wet spot it caused.

My bet is that you have a leak under the slab which shows up at multiple places near the slab edge.

First DIY step is to determine whether the leak is on the house or yard side of the house cutoff. Shut the cutoff and monitor the water meter near the curb. A small triangle (red on mine) will not move over 30min after shutoff if the leak is in/under the house. It will move if the leak is in the yard.

If the leak is on the house side call a leak-detection specialist or a full-service plumber that offers that service.

If in the yard, see if anybody in your area offers resistance or acoustic leak location technology. Digging will be cheaper.

My leak was under the kitchen floor in the line feeding the fridge icemaker. The plumber ran pex through the attic to replace the bad section of pipe. It required 2 very small holes at base of wallboard easily covered by access plates.

have a flower bed with bricks surrounding it that has drains in the bricks - water coming out of those holes

That sounds like a rather significant leak

What you have is kind of perplexing. Are the two pipes going into the house PEX, steel, or copper?

PVC

I've been cutting off the water in the house and on the street

Thanks for updates.

If those two PVC lines are supply, where is the at-the-house shutoff valve? Most I've seen are above the slab and right at the wall.

Such a weird angle for them to enter the green pipe. How old is the house? Wondering if it’s shifted.

Looks like a lot of water, is that clean out a sewer line?

I would abandon the pvc under the house. Cut it and reroute it through the brick wall (with copper) and tie it in under the stove where your valve is.

PVC under concrete is a time bomb. Should always be one solid piece of pipe, no fittings under concrete. Lets say you find and fix the leak...you're gonna back fill the saturated ground. The ground is going to dry out over the summer and settle. The fix you just made is going to be in a bind again and is on a timer for the next time it breaks.


A irrigation guy is not someone I'd want doing it either. They profit on volume and quick fixes and use cheaper fittings/piping and glue. <- Not valid if it is someone you know for certain does quality work.
