Ground Loop Repair Questions

The loop field is segmented and each run is pressurized individually to isolate the failing section. Tracer gas or dye is then introduced into that segment to surface at the exact fault point. Targeted potholing exposes only that area, keeping the rest of the yard untouched.

No. A damaged section can often be spliced or replaced if the rest of the loop is still sound. Full replacement is considered only when multiple sections are failing or the pipe condition is too degraded to repair reliably.

Continued fluid loss lowers heat exchange efficiency, causes the system to short-cycle, and raises heating and cooling costs. Glycol dilution from repeated refills can also drop freeze protection below Colorado winter requirements, risking pipe damage.

Sealants are not a confirmed repair for an active loop leak. Pressure loss typically returns, and the loop still needs a proper splice or section replacement. A pressure hold test after any repair is the only way to confirm the fix held.

Many repairs use targeted potholing to reach only the problem area, which is far less disruptive than opening the full loop field. The actual excavation footprint depends on the leak location, burial depth, and whether the pipe runs under hardscape.

The loop is pressure tested to confirm it holds at spec, then flushed and refilled with glycol at the correct antifreeze concentration for Colorado temperatures. A post-repair system check confirms stable heat exchange before normal circulation resumes.
