• Flush the water heater to remove sediment buildup

• Inspect vent pipes and remove any visible debris

• Test the sump pump by lifting the float switch or filling the sump pit with water

• Empty and clean the sump pump and pit

• Test the water meter for leaks

• Check outdoor hoses, faucets, and sprinklers for leaks

• Test outdoor water shutoff valves

• Pump the septic tank every three to five years

• Clean the sewer line with a cleaning agent and snake

• Divert water runoff away from any soggy spots in the drain field

How Much Does It Cost to Hire a Plumber?

The average cost to hire a plumber ranges from $180 to $495. However, the exact price varies widely based on the type and extent of the repair. Plumbers typically charge by the hour, but they may add flat fees for certain services, such as unclogging drains, checking water pressure, and installing appliances.

If you’re looking for a general plumbing inspection, expect to pay between $100 and $400, depending on home size, location, and required equipment.

DIY vs. Hiring a Pro

Homeowners can and should regularly perform basic plumbing maintenance tasks on their own. That said, it’s often worth hiring a local plumber to guarantee every aspect is accounted for and properly addressed. A plumber will inspect every part of the plumbing system, from pipes to appliances, and ensure that everything flows as intended. Hiring a plumber is especially recommended for complex repairs, as a single mistake could exacerbate the situation.
