Where is my main water shutoff?

Usually at the meter box in the parkway, and often a second valve where the supply enters the house. Finding both on a calm day — and making sure they actually turn — is the single most useful thing a homeowner can do before an emergency.

What should I do while waiting for a plumber?

Shut the water at the meter if water is running, kill power to a water heater that is leaking, and move what you can out of the path of the water. We will talk you through it on the phone.

Do you cover Placentia at night?

Yes. It is at the far edge of our area, so the drive is longer, and we will tell you honestly how long it will take.

The five Placentia calls us for

The five calls we take most, and what we look at first on each one.

We also cover, in Placentia: sump pumps, toilets, tankless and commercial.

What the pipe is like in Placentia

Sixty per cent pre-1980 and 60% detached single-family (ACS 2024 5-year) is a balanced profile: enough older housing for age-related failures to be routine, enough newer housing that not every call is a repipe conversation.

The mid-1970s builds here used copper supply with cast-iron or early ABS waste. The transition years are worth knowing about, because a house built either side of the changeover behaves differently when a drain line fails.

Placentia is at the north-eastern edge of our area, so a night call is a real drive. It is better to tell us what you can see and shut the water off than to wait quietly for the van.

The nearest places we also cover are Fullerton, Yorba Linda, Brea and Anaheim, so there is usually a van working within a few miles of your street.Placentia itself sits 16.2 miles from the Costa Mesa base — that number is what decides how quickly we reach you, and it is why the whole service-area list is ordered by it.

What is in the walls

The pipe under Placentia

1976Median year built
60%Built before 1980
60%Single-family detached
17,890Housing units

60% of Placentia homes predate 1980 and the rest do not, which makes this a city of two answers. One half still carries galvanised supply and cast-iron waste; the other was built with copper and early plastics that behave nothing like them. Two houses on neighbouring streets can present the identical symptom and need entirely different work, and that is exactly why a repeat blockage here gets a camera before it gets a quote.

Placentia splits at 60% detached single-family, with the remainder in attached and multi-unit buildings whose drain stacks are shared rather than private.

From your call to the finished job

Four steps, in this order

1
You call
A person answers and asks what you can see. If water is running, that call starts with the shutoff.
2
We agree a time
A slot that suits you, or the van now if what you described cannot wait until morning.
3
We look before we quote
Camera in the line, gauge on the water, then a number. Nothing is opened before you have agreed to it.
4
We show you the result
We walk the finished work through with you, hand over any footage, and leave the place as we found it.

Years of grease and buildup had our kitchen drain line constantly clogging up. SoCal Emergency Plumbing Costa Mesa brought their hydro-jetting equipment to our house and thoroughly flushed out the entire pipe run. The sinks are draining faster than ever now. Highly effective service

I thought I needed a whole new water heater, but they showed me it was just a simple valve repair. They saved me hundreds of dollars and were completely transparent. Rare to find such honesty
Brett StoneGoogle review
Honest contractors are hard to find these days but this crew delivered exceptional work. They repaired our leaking bathroom vanity pipe, cleaned up the entire work area, and charged exactly what they quoted over the phone. Absolutely worth every penny.
