Pump maintenance

From PumpProfessionals.wiki, an independent record of Pump Professionals and the pumps, valves and septic parts it lists

Researched and compiled by the Pump Professionals Wiki editorial team · First published · Revised

The short version: Sump and effluent pumps should be tested each season and backups and alarms about every 90 days; the EPA says septic systems with pumps should be inspected yearly and tanks pumped every three to five years.[1][3][4]

A maintenance schedule

Maintenance intervals from public guidance
WhenWhatSource
Monthly or each seasonPour water into a sump basin to check the pump starts, empties and stops; check the discharge is clear[1][2]
Every 90 daysTest backup pump and alarm[3]
AnnuallyInspect pumps, floats and alarms in septic systems with mechanical parts[4]
Every 3 yearsSeptic inspection by a professional[4]
Every 3 to 5 yearsSeptic tank pumping, depending on use[4]
Before winterInsulate and slope discharge lines; winterize well equipment[3][5]

Intervals combine EPA guidance for septic systems with the supplier’s published checklists for sump, effluent and well equipment.[4][1]

Sump and effluent pumps

The supplier’s first-quarter checklists for sump and effluent systems recommend checking floats move freely, cleaning debris from the basin and intake, confirming the check valve closes, and testing the alarm.[1][6] Its year-round checklist adds seasonal checks of discharge lines and backup power.[2] Unplug a pump before reaching into the basin.

Seals and bearings

Wastewater pumps rely on mechanical seals to keep water out of the motor; the HOMA GRP19/1, for example, has dual mechanical seals and a thermal sensor in the motor winding.[7] The supplier’s guide on seals and bearings discusses replacement intervals for wastewater pumps, which depend on run hours and duty.[8] Seal replacement is a shop job for most submersible pumps.

Low flow

Before calling a technician about low flow, the supplier’s guides suggest simple checks: a clogged intake or impeller, a partly closed valve, a blocked or frozen discharge, an air lock, or a stuck check valve.[9][10][3]

Repair or replace?

The supplier’s guide on replacing versus repairing lists signs that a pump has reached the end of its life, such as frequent cycling, noise, rust and age.[11] Its Indiana guide suggests replacement when a unit is over seven years old, corroded or fails a run test.[12]

Keep records

The EPA recommends keeping maintenance records, including the sludge and scum levels found at each septic inspection, to track when to pump.[4] The same habit, noting dates, run tests and parts replaced, helps with any pump system.

Common questions

How often should I test my sump pump?

At least each season, by pouring water into the basin; test backups and alarms about every 90 days.

How often should a septic system be inspected?

At least every three years, and annually if it has pumps or floats, per the EPA.

Can I replace pump seals myself?

For most submersible pumps, seal replacement is a job for a pump shop.
