Frequently Asked Questions

How often do I change the cartridge? Most sediment + carbon combos last 6 months or 100,000 gallons, whichever comes first. Hard water areas may need quarterly changes.

Will this lower my water pressure? A properly sized system reduces pressure by 2-5 PSI — completely unnoticeable. An undersized system can choke flow significantly, so size up if in doubt.

Can I install this ? Absolutely. The principles are identical — just use the appropriate fittings and connectors for your pipe type.
