Whole-Home Pre-Filtration

Stop Sediment Before It Starts

Coarse sediment — sand, rust, silt — is the first thing that should be pulled out of your water supply, before it reaches your pump, cartridges, or UV sterilizer. A pre-filter installed at the point of entry protects every stage that comes after it and extends the service life of your whole system.

Two Ways to Catch It

Choose Your Pre-Filter

Both are coarse, first-stage filters — the choice comes down to how you want to maintain it and how much room you have to install it.

Spin-down sediment filter with clear bowl and stainless mesh screen
RECOMMENDED

Spin-Down Sediment Filter

A clear bowl with a reusable stainless-steel mesh screen inside — you can see exactly how much sediment it's catching, and flush it clean in seconds with the bottom valve. No cartridges to buy or replace.

  • Clear housing lets you see sediment buildup at a glance
  • Flush-clean maintenance — no replacement cartridges
  • Reusable stainless mesh screen, typical rating around 100 micron
  • Compact footprint, straightforward point-of-entry install
Best for: well water and groundwater with sand, silt, or rust — the common case in Bali.
Brass Y-strainer with removable mesh basket
COMPACT ALTERNATE

Y-Strainer

A solid brass or stainless body with a removable mesh basket inside — unscrew the cap, rinse the basket, and reassemble. Handles higher pressure and temperature than a clear spin-down bowl.

  • Higher pressure and temperature tolerance than clear housings
  • Compact, low-profile fitting for tight mechanical rooms
  • Durable brass or 304 stainless steel construction
  • Simple unscrew-and-rinse maintenance
Best for: tight installation spaces, or where a clear housing isn't practical.

Keeping It Running

Maintenance

Spin-Down Filter

Open the bottom flush valve for 5–10 seconds every 1–2 weeks — more often during wet-season or high-sediment periods. No parts to replace.

Y-Strainer

Shut off the supply, unscrew the cap, rinse the mesh basket, and reassemble. Check monthly at first to establish the right cleaning interval for your water source.
