Annual plumbing inspection checklist

Annual plumbing inspection checklist

A whole-home plumbing check you can sell as a yearly visit. Follow local code and the manufacturer instructions for each fixture and appliance.

Water heater

• Check the temperature setting and the T&P relief valve
• Flush sediment from the tank
• Inspect the anode rod (tank units) and note its condition
• Check venting and gas connections (gas units)
• Tankless: clean the inlet filter and descale if needed

Supply and pressure

• Measure static water pressure
• Check the main shutoff valve operates
• Inspect visible supply lines and angle stops
• Check the pressure-reducing valve and expansion tank

Fixtures and drains

• Run every faucet and check for drips
• Check each toilet for running, rocking and wax-ring leaks
• Test drain speed on sinks, tubs and showers
• Check under sinks for leaks and corrosion
• Test the sump pump and check the discharge

Outside

• Check hose bibs and backflow devices
• Look for wet spots that could point to a slab or yard leak
• Note the sewer cleanout location for the record
