SIX7 PLUMBING
Colombo Apartments & Marine Drive — We Know the Booster Pumps.
From Bambalapitiya to Wellawatte, Marine Drive apartments run on two-pump systems that fail at monsoon peak. We fix sump pumps, booster pumps, and the tile-buried leaks that drop your pressure without a visible drip. Colombo 1–15 · 60-minute dispatch zone — quoted before we move.

Common Jobs in Colombo
The fault types that come up across Colombo 1–15, and what the work involves.
Local Colombo Expertise
The common assumption is that toilet clogs top the list of apartment emergencies. In Colombo 1–15 they do not — sump pump failures and booster pump burnout do, because clogs are rare where toilet paper use is minimal in most buildings.
Dominant pipe material is PVC across Colombo 1–15. Affluent neighborhoods — Nelson Place, Sri Saranankara Road gated residences — often have thicker 3/4" PVC instead of standard 1/4". When these pipes are cut, proper joints are hard to find, so technicians fall back on heat-formed socket joints or adapters. Not pretty, but it holds.
Apartment blocks here run a two-pump setup: a bottom pump pushes water up, a smaller pump at the tank foot repressurizes. When one dies, the whole building feels it — which is why pump work, not clogs, fills the diary at monsoon peak.
Monsoon brings sump pump surges and tree falls breaking external pipes. Dry season brings low pressure complaints — main-side or internal.
Common Failures In Order Of Frequency
- Sump pump repair and cleanup (monsoon peak)
- Booster pump failures in two-pump systems
- Burst pipes from standard pressure spikes
- Wastewater blocks in 40+ year homes — toilets wired to sewers by original contractors, unknown layouts meaning expensive surprise jobs
- Low pressure from internal leaks: tile socket connections decay and crack inside walls, dropping pressure without a visible drip; small cracks break when techs try removal, forcing full replacement
