Signs your pump needs attention

A pump usually warns you before it quits. Listen for a loud hum or rattle. Watch for flow that weakens week after week, water that spurts or surges, or an outlet that keeps tripping. A pump that's hot to the touch or smells like burning is already in trouble. Catch it early and the fix may be a cleaning instead of a new pump.

Check two things first. Is the water high enough to cover the pump? Is the intake clear of leaves and pine needles? If both are fine, unplug the pump so it can't overheat and call us. The fountain troubleshooter walks through the other likely causes.

Pump repair

Many pump problems are clogging problems. Algae, mineral scale, sand and plant debris get sucked into the intake and wrap the impeller, the flow slows and the motor strains. A repair means taking the pump apart, cleaning the intake screen, impeller and housing, and checking the seals and cord. Most pump repairs run $50 to $400.

What sits around the pump matters too. A pump resting on the bottom of a dirty basin will clog again fast, so raising it or adding a pre-filter often helps. Kinked or scale-crusted tubing gets replaced in the same visit.

Pump replacement

Some pumps aren't worth saving: a burned-out motor, a broken impeller shaft, a cracked housing. Replacement runs $300 to $900 installed for most fountains, depending on size and how hard the pump is to reach. Large pond and waterfall pumps cost more. The price comes to you in writing first.

Sizing decides whether the new pump works. Too small gives a weak trickle. Too big throws water out of the basin until the pump runs dry. A pump matched to the fountain looks better, draws less power and lasts longer. Skip the bargain model if it's rated for a lower lift than your fountain needs; it will struggle from day one.

Keeping a pump alive

Pumps die young for a few predictable reasons, and you can head off most of them. Keep the water level up, especially in hot, windy weeks when evaporation is high. Clear the intake during pollen season and leaf drop. Unplug the pump before a hard freeze or a storm outage, then confirm it restarts when power comes back.

If you'd rather not track all that, ask about regular cleaning visits when you request an estimate. Clean intakes keep a pump cool and catch small problems early. Pond owners can read about pond and waterfall repair, and the cost guide shows what each job usually runs.

Questions about fountain pumps

Why does my fountain pump keep tripping the GFCI outlet?

A pump that trips a GFCI usually has water getting into the motor or cord, a damaged cord, or a failing motor. Sometimes the outlet itself is worn out or sharing a circuit with too much else. Unplug the pump and don't keep resetting it, since repeated trips around water are a safety warning. We'll test the pump and outlet to find which one is the problem.

Can a fountain pump be repaired or does it always need replacing?

Many pumps can be brought back with a thorough cleaning of the intake, impeller and housing, especially when the issue is clogging or mineral scale. If the motor is burned out, the shaft is damaged or the housing is cracked, replacement is the better value. We always check the cheaper fix first.

What size pump does my fountain need?

It depends on how high the water has to be lifted and how much flow you want over the tiers or spillway. Pumps are rated in gallons per hour at a given lift height, and that rating drops as the height goes up. We measure your fountain and match the pump so the flow looks right without splashing out of the basin.

How long do fountain pumps last?

Most last about three to five years of daily use, and longer when they're kept clean and never run dry. Running the pump with the water too low is the fastest way to kill one.
