Monterey Park is largely post-war housing on slab, much of it on sloping ground, and slab construction shapes what we find here.
A slab leak does not announce itself. The supply line is under concrete, so the water goes sideways through the slab and into the flooring and the base of the walls before anybody sees anything.
What goes wrong in Monterey Park homes
Warm spots on a floor, an unexplained rise in the water bill and the sound of running water with everything closed are the three signals. Any one of them is worth a call.
On sloping lots the other issue is what the hillside does in a storm. Water moving downhill collects against whatever is in its way, and a house cut into a slope is in its way.
There is a warm patch on my floor. Is that a leak?
Often, and it means the hot water line under the slab. It is one of the few slab leak symptoms you can feel, and it is worth acting on rather than watching.
Does the whole floor have to come up to fix a slab leak?
No. The line can often be rerouted overhead rather than chased through the slab, which is less destructive. Finding it precisely first is what keeps the work small.
