Water Purifier & RO System Repair, Service & Installation
Slow flow, odd-tasting water, or a unit that's stopped producing purified water altogether — FETSCO installs, services and repairs RO and other water purification systems.
Common Water Purifier / RO System problems we fix
Common issue
Low or no water flow from the purifier
Likely cause: A clogged pre-filter, a fouled RO membrane, or low inlet water pressure.
How we fix it — We replace the pre-filter and test membrane performance, replacing it if it's past its service life.
Common issue
Water tastes or smells off
Likely cause: An exhausted carbon filter, or a storage tank that hasn't been sanitised in a while.
How we fix it — We replace the carbon filter and sanitise the storage tank as part of the same visit.
Common issue
Purifier leaking
Likely cause: A loose fitting or a failed O-ring at a filter housing joint.
How we fix it — We identify and reseal or replace the specific fitting causing the leak.
Common issue
Purifier running continuously / motor won't stop
Likely cause: A faulty float switch or pressure switch not signalling the tank is full.
How we fix it — We test and replace the float/pressure switch.
How we install your water purifier / ro system
Water source & pressure check
We test your inlet water pressure and quality to confirm the right system and filter stages for your water.
Under-sink or wall mounting
Unit mounted securely with all filter stages accessible for future servicing.
Plumbing & tank connection
Inlet, drain, storage tank and dispensing tap all connected and pressure-tested for leaks.
First-run flush & test
New systems are flushed per manufacturer instructions before the first drinking-water test.
Genuine parts, every major brand
Water Purifier / RO System repair — questions we get
Pre-filters typically every 3–6 months and the membrane roughly every 12–24 months, depending on your water quality and usage — we can set up a reminder schedule as part of an AMC.
Yes — under-sink and wall-mounted installations are both routine for us.
Yes, including office and light-commercial RO systems.
Often just a filter due for replacement or low inlet pressure — worth a quick check before assuming a bigger fault.
