SIX7 PLUMBING
SIX7 Plumbing Sump Pump Repair Colombo
Humming but no water is an airlock or a blocked impeller — freed and primed on the spot in most cases. Floats die before motors; we test before we replace anything.
The triage is short: airlock (prime the line), scale-seized float (free or replace), blocked impeller (clear and test), burned motor (quote replacement first — we don't bill labor chasing a dead motor). Run-test under load closes every visit. Because sumps fail more than boosters here, this is one of our most frequent monsoon-season calls, and priority dispatch applies when water is rising right now.
Pumps that run non-stop usually have a failed float or a stuck switch — running dry is how a repairable pump becomes a replacement, so the call is worth making early. Old pump disposal is included when we fit a replacement.
60-Min ETA

Common Sump Pump Repair Issues We Fix
Pump hums, no flow
A humming pump with no water movement is usually an airlock or blocked impeller. We fix it on the spot in most cases.
Never starts
If your pump won't start at all, the motor or float switch may be dead. We test and replace what's needed.
Runs non-stop
A pump that never stops is either a stuck float or a failed switch. We adjust or replace the float mechanism.
Flood despite the pump
If your basement floods even with the pump running, the pump may be undersized or the check valve failed.
How We Fix It
Diagnosis
We test the switch, the impeller and the discharge head separately - a dead pump is three different faults.
Quote
The quote names the failed part and its price; if the motor is sound, you are never sold a new unit.
Repair
We free or replace the impeller, renew the check valve and set the switch to the correct on and off levels.
Verify
We flood-test the pit through a full cycle and time the discharge before we close the lid.

Prevention
- •Pour water into your sump pit monthly to test the pump. If it doesn't kick on, call us before the next storm.
- •Keep the area around your sump pump clear. Debris can jam the float and cause flooding.
When To Call Us
- •A stuck float during a storm = a flooded basement. Every hour you wait increases the damage.
- •An impeller jam reads like a dead pump — we free the blockage first, before anyone quotes you a new motor.
