What happens if I leave filters too long?

Neglected filters can become breeding grounds for bacteria and may let contaminants through. They also reduce pressure and make the system work harder, which leads to premature failure.

Do you service systems you didn't install?

Yes — we service most brands and setups. If parts are hard to source we'll tell you upfront and talk through the options.
