Sized for flow, not for how long it lasts
This is the mistake that makes people regret whole house filtration.
Cartridges are sold with a capacity, so many thousand litres or so many months. That number describes how long it lasts. It says nothing about how much water it can pass at once.
Every filter presents resistance. One that is undersized for the property’s peak simultaneous demand throttles everything downstream: the shower weakens when the washing machine fills, taps slow when a toilet refills.
The symptom looks like a supply problem and it is a filter that was chosen on the wrong specification.
Sizing follows peak flow. Staging the media, sediment first and finer filtration after, helps too, because the fine cartridge is not being loaded up with grit it was never meant to catch.
Fit gauges and a bypass
Two inexpensive additions decide whether the system is maintained.
Pressure gauges either side of the filter. As a cartridge loads, the difference between the two readings grows. That difference tells you when a change is genuinely due, rather than relying on a manufacturer’s estimate based on water and usage that may not resemble yours. It also tells you when a filter is restricting flow before anyone complains about the shower.
A bypass valve. Without one, changing a cartridge means shutting off the water to the whole property. With one, it takes minutes and nothing else stops.
A filter that is awkward to service does not get serviced, and an unserviced filter eventually restricts flow while removing nothing. Both fittings cost very little at installation.
Does this sound familiar?
Problems this service solves
- Sediment reaching every fixture and appliance
- Chlorine affecting showers and laundry as well as drinking water
- Grit damaging valves and cartridges throughout the house
- A well supply carrying fine material
- Staining on fixtures and laundry from iron
Signs you need whole house water filter
If more than one of these is true, the problem is usually past the point a plunger or a store-bought cleaner will fix.
- There is grit in aerators throughout the property
- Chlorine is noticeable when showering
- Fixture valves are wearing out unusually fast
- The supply is a private well
What to expect
How the visit works
Confirm it is a whole house problem
Drinking water taste is a point of use issue. Sediment and chlorine affecting fixtures and appliances is what justifies filtering everything.
Size for peak flow
The filter has to pass the property's peak simultaneous demand without restricting it, which is a different calculation from cartridge life.
Stage the media
Sediment first, then carbon or specialist media, so the coarse material is removed before it loads the expensive cartridge.
Fit a bypass and pressure gauges
A bypass keeps the house in water during a cartridge change, and gauges either side show when the filter is loading up.
What's included
What you get on every job, whoever we send.
- Sized against peak demand rather than cartridge life
- Media staged so the fine filter is not doing coarse work
- A bypass so filter changes do not shut off the property
- Gauges that show when a change is actually due
Questions
Whole House Water Filter questions
Will a whole house filter reduce my water pressure?
It will if it is sized on cartridge capacity rather than flow, and that is the most common mistake with these systems. Every filter presents some resistance, and one too small for the property's peak demand throttles everything downstream, so showers weaken whenever another fixture runs. Sizing against peak simultaneous flow, and staging the media so the fine cartridge is not doing coarse work, avoids it.
Do I still need a filter at the kitchen tap?
Often yes, and the two do different jobs. A whole house filter is sized for flow, which limits how thorough it can be; it handles sediment and chlorine across the property. A point of use filter treats a few litres a day, so it can be far more selective, which is what you want for drinking water. Many houses have a whole house filter for the fixtures and reverse osmosis at the sink.
How do I know when to change the cartridge?
Pressure gauges either side of the filter are the honest answer, and they are worth fitting at installation. As the cartridge loads, the difference between the two readings grows, and that difference tells you when it is genuinely due rather than when the calendar says. Without gauges you are relying on a manufacturer's estimate that assumes a water quality and a usage pattern that may not be yours.
