Float valve is broken — tank overflow and a fatter electricity bill
A dead ball cock lets the motor run until the roof turns into a waterfall. Fit a new float, add a dry-run or timer, and stop paying to pump water into the drain.
Tank & RO
Overhead overflow, underground smell, RO waste, cracked plastic tanks, and broken float valves.
Plastic tank on the roof has a crack and is leaking
A hairline crack on a Sintex-style tank wastes the only hour of supply. Empty to a safe level, patch only as a stopgap, and budget a replacement before peak summer.
Rainwater pipe is dumping dirty water into the tank
A broken first-flush or a terrace drain tied into the drinking tank will muddy the whole week. Separate the pipes before the next rain, not after.
When should you change the RO filter if TDS jumped overnight?
A sudden TDS jump is not always a scam. Source water changed, a membrane clogged, or a tank mixing reject with product. Test twice before you buy a full kit.
RO waste water is overflowing the tank
Reject water has to go somewhere. If the drain is blocked or someone tied waste back into the same tank, you get overflow, smell, and a higher motor bill.
The underground tank smells after cleaning
Bleach leftover, a dead lizard, or a lid that never sealed will stink for days. Flush, test, and do not drink until the smell and a simple check both settle.
Overhead tank overflow is damaging the neighbour’s wall
A stuck float valve can send water into someone else’s room. Stop the motor, photograph the stain, and fix the ball cock before the society turns it into a fight.
