SIX7 Plumbing Water Pressure Restoration Colombo
One tap weak is a leak. Whole house weak with no tank is a mains problem. Whole house weak with a tank is a pump problem. We fix the one you actually have — and we'll tell you when the honest answer is "call the water board".

Is this your problem?
- One dead tap, rest fine
- Whole house weak, no tank
- Tank exists, pressure still sags
- Upper floors starve at peak hours
The decision tree we work through on site: pressure missing at one fixture means an internal leak or failed component — replace it and pressure returns. Housewide low with no tank means the mains line is undersized; a pressure pump bolted onto a weak main is money wasted, and we say so. The real fix is a tank with a pump at its foot repressurizing the lines on re-entry — and where a tank exists but pressure still sag, a second pump stages the supply.
The last branch nobody likes: if mains pressure itself is the problem, the correct engineering is a 3/4-inch board main converted per sector or per house. Almost nobody goes to that length — unless they want, as one customer put it, a water cannon in the house — so we quote the practical tank-and-pump configuration instead and leave the board option in writing.
Labor is 3,500/hr; the pump itself is a supply item quoted separately, and depending on model and quality runs well past LKR 50,000. You approve that number before we order anything.
"Bigger pipes solve low pressure."
Diameter is the last card we play — scale, half-closed valves and clogged aerators cause most losses, and each costs a fraction of repiping.
Restoration runs in order — verify the supply, clear the restrictions, rebalance the fixtures — and a pump joins only at the end, if at all.
Cause
Scale-choked lines, dying pumps, stuck valves, mains-side loss and hidden leaks all read as 'weak pressure' at the tap.
How We Fix It
Measure at points, isolate the cause, descale or replace as needed, pressure-test after restoration.
Test your pressure at every outlet after the work - a fix that holds at the basin but drops at the shower was never finished.
Pressure loss rarely recovers on its own — scale and worn valves only close further with every use. Don't ignore it until the tap runs dry.
Descaling a chocked line restores pressure without touching the pump — the same hard water that cooks geyser elements narrows your pipes.
What to Do Before We Arrive
- Test one tap at a time and note the weak ones — a single low tap is a valve, whole-house low is supply or scale.
- Rinse the aerator on any weak tap — trapped sediment alone can mimic lost pressure.
- With all taps closed, watch the meter — a spinning dial means a hidden leak is bleeding pressure away.
- Note when pressure dropped — after roadworks, after the tank ran dry — timing points at the cause.
