An outdoor master filter on the main line catches sediment before it reaches your taps, heaters, and washing machine. Point-of-use filters under the kitchen sink are for drinking water.
Signs you need it
Brown water after supply interruptions, sediment in the toilet cistern, stained sinks, or a filter that has not had its cartridges changed in a year.
What the technician does
The technician finds the main line after the meter, cuts in the filter housing with isolation valves and a bypass, and flushes it through. Under-sink units are fitted to the cold line with their own tap.
What to send us
Photos of your water meter and the pipe run near it, your property type, and the brand of any existing filter.
