Real-World Advice: Pipe Sizes & Pressure Drops
The biggest error made when ordering whole-house systems is choosing the wrong pipe connection size, resulting in a throttled water supply. If your water meter feeds your house with a 25mm (1-inch) copper pipe, do not buy a 20mm (3/4-inch) filter system just because it is cheaper. You will create a bottleneck that drops your shower pressure the moment the washing machine turns on. Always match or exceed the diameter of your main incoming pipe.

Actionable Guide: Where to Mount the System
Whole-house systems are heavy when full of water and require regular maintenance.
Height: Mount the bracket at waist height so you can easily use the filter wrench to unscrew the heavy bowls.
Clearance: Ensure there is at least 150mm of clear space beneath the housings, or you won't be able to drop the bowls down to change the cartridges.
Sunlight: If mounting outdoors, ensure you have an opaque (solid) cover to prevent sun damage to the plastics and stop algae growth inside the bowls.
Frequently Asked Questions
Do I need a plumber to install a whole house water filter?
Yes. These systems require cutting into your property's primary pressurized water main. It involves professional pipe fitting, isolation valves, and ensuring the setup meets local plumbing codes to prevent catastrophic leaks.
Will this fix the bad taste in my water?
Absolutely. By putting a large carbon block at the point of entry, chlorine and organic compounds are stripped out immediately. You will have bottled-quality tasting water at the kitchen sink, and you won't be breathing in vaporized chlorine gas in a hot shower.
