The failures you never hear about
Most plumbing emergencies are slow-moving faults that no one noticed: a dripping PRV that erodes a valve seat, a booster that short-cycles a thousand times a month, a choked vent that smells fine for a year before the ceiling stains. Preventive maintenance finds these on a calendar, not a crisis.
- Pressure-test sight glasses & PRV set points monthly
- Inspect booster pumps & hold a standby run record
- Clean strainers at every riser drop quarterly
- Dye-test WC & urinal cisterns to find silent leaks
- Check vent stacks for blockages before the rains
Rule of thumb
On a commercial building, every rupee spent on preventive plumbing maintenance saves roughly seven rupees in reactive repairs and water bills.
