An El Mirage plumbing inspection is a plumber's check of the water heater, supply and drain lines, fixtures, shutoffs, pressure and any backflow assembly, with a sewer camera run if wanted. It gives buyers a list of repairs to negotiate and owners a plan for aging parts. Call the number on this page to be connected with a local plumber in El Mirage.

El Mirage sits on the west bank of the Agua Fria River and runs its own water and wastewater systems. The city's water system also serves the Original Town Site of Surprise. Its 2024 water report lists hardness of 4 to 9 grains per gallon, averaging 7, which is softer than much of the Valley, so heavy scale is less of a given here than in many nearby cities.
What to do now
- Ask the seller for the water heater's age and any repair receipts.
- Check whether a softener is installed; at about 7 grains, some owners skip one.
- Locate the meter, main shutoff, cleanout and any backflow assembly.
- Run all fixtures and note drips, slow drains or noisy pipes.
- Book the plumber early in the inspection period.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Water heater leaking from the relief valve | High pressure, high temperature or a failing valve |
| Toilet running between flushes | Worn flapper or fill valve |
| Main drain backing up into a tub | Blockage in the line to the city sewer |
| Wet area near the meter | Service line or fitting leak |
| Hot water slow to arrive | Long run or failing recirculation setup |
Cost factors
- Home size and fixture count
- Adding a sewer camera run
- Access to the heater and shutoffs
- Formal report needs
The city is identifying service line materials across its water system, so a plumber can note what the line is where it enters the house. Under City Code 14-10, customers must have backflow assemblies tested at least yearly by a certified tester on the city's list, who files the results. Follow-up permits go through El Mirage Development Services Building Safety. If you smell gas, leave the house first, then call 911 and your gas utility.
Even with softer water than much of the Valley, El Mirage homes see the usual desert wear: hose bibs and irrigation lines that bake in summer, relief valves that start to weep and toilet parts that wear out. A written list from the plumber lets you separate what to fix before closing from what can wait. Ask for photos so you can share them with the seller's agent.
