SIX7 Plumbing Sump Pump Installation Colombo
Sized for your worst monsoon night, not your average one: volume and head calculated, float levels set, check valve fitted, full-flow tested before handover.
T&Cs apply — /pricing/ & /disclaimer/
Size & Spec
Calculate volume and head height for the right pump.
Install
Fit pump, set float levels and check valve.
Load Test
Run-test at full flow before handover.
In Colombo's apartments and flood-prone lows, sumps fail more often than boosters — and undersized sump pumps fail exactly at monsoon peak, when the inflow exceeds them. We calculate volume and head height, fit a pump that beats both, set float levels and check valve, and run-test at full flow before we sign it off. A pump that can't win your worst night gets returned, not commissioned.
The 15,000 base covers a standard sump pump supplied and fitted with non-return valve and discharge line; higher-head or higher-volume units are quoted from the survey. We also sell pump maintenance contracts — scheduled test visits priced below call-out rates — because the pump you never test is the pump that fails in June.
6-Month Shield
Every installation is backed by a 6-month workmanship warranty.
Pay After Approval
You only pay once you have seen the work and approved it.
Upfront Pricing
We quote before we start. No hidden fees — the price we quote is the price you pay.

"Sump pumps are sized to the pit and the water table, not to whatever box is on the shelf — size first, install second."
