Water – Leak in boiler system

boilerleaksundergroundwater

Have concrete slabs heated with an HTP boiler. 4 manifolds (2 supply, 2 return w/shutoffs). Had a loss of pressure and low water pressure error on boiler. I have isolated the leaks off the manifolds. Yeah, more than one. They are running city water through this to heat the concrete at a car wash in the hand bays. No no.

Question: Is there anyway to fix those leaks? They're running underground through hose…looks half inch. Thx

There are sealing systems for pinhole leaks in copper water piping water under slabs. The pipe is sandblasted or media-blasted in place and then coated in place with epoxy. This may or may not work for the high temperature water or steam you are using here.
