Plumbing Leak Detection for South Whittier Homes

In homes that have been updated piece by piece over the decades, it’s common to find newer fixtures connected to much older supply lines and shutoff valves. Those transition points — angle stops, old hose bibs, and water heater connections — are worth a careful look.

When you know something is wrong but not where, a systematic check finds the cause fast, whether it’s a toilet, a fitting, or a concealed line.

Common Questions

Who is my water provider in South Whittier?

It depends on your street — more than one provider serves the area. The provider’s name is printed on your water bill, and that’s who to contact about the meter or any issue on the street side.

My water heater is leaking. Does that need leak detection?

If water is coming from a fitting or the relief valve, the issue is usually visible and repairable. If the tank itself is leaking, replacement is typically the solution. Detection matters most when you can’t tell where the water is coming from.

Is a running toilet really a leak?

Yes. A toilet that runs or refills on its own is leaking water from the tank into the bowl, and it can waste a surprising amount over a billing period. It is usually an inexpensive repair.
