You need this if…
Your main shut-off is seized, corroded, or won’t fully close
You don’t know where it is — or it’s buried behind landscaping
You have an old gate valve (these fail exactly when you need them)
There are no individual shut-offs at toilets, sinks, or the water heater
You travel and want automatic protection while away
You’re already adding an earthquake gas valve — do both at once
Not sure if yours works? We’ll test it.
The valve that fails when you need it
Here’s what we see constantly in LA-area homes: the house has a main shut-off, but it’s a decades-old gate valve that hasn’t been turned since the Reagan administration. When a pipe finally bursts and someone runs out to close it, the stem snaps or the gate won’t seat — and the water keeps coming while the house floods.
In older neighborhoods across Pasadena, Alhambra, Glendale, and the pre-war Valley tracts, that’s the norm, not the exception. The fix is simple and cheap compared to water damage: replace tired gate valves with modern quarter-turn ball valves (one 90° turn, no seizing), add fixture shut-offs so you can isolate one toilet instead of the whole house, and — if you want real protection — install an automatic leak-detection shut-off that closes the main by itself when it senses a leak or abnormal flow.

Cost
A main valve replacement is a modest, straightforward job; fixture shut-offs are inexpensive add-ons; an automatic leak-shut-off system costs more but protects an unoccupied house. Written price up front after we see the setup — access and pipe material drive the number. You approve before we start.
