The Large 2" Rusco ($165) handles 18 to 100 GPM, which is 4x the flow capacity of the Standard 1" ($145, rated 1 to 25 GPM). Get the Large if you have 3+ bathrooms, run sprinkler zones off the well, have agricultural / barn / shop water demand, or want a single pre-filter that protects everything in a high-flow whole-house treatment system. The Large uses 2" slip PVC connections that are typically reduced to 1.5" or 1.25" for residential plumbing. The Standard threads directly into 1" lines and is the right choice for smaller homes or as a post-softener resin trap.

Use PVC reducer fittings. The 2" slip ports glue to standard 2" PVC schedule 40, and you can buy 2" slip x 1.5" slip or 2" slip x 1.25" slip reducers at any plumbing supply or big-box hardware store. Glue with PVC primer and cement, let cure 30+ minutes before pressurizing. The reduction does narrow the inlet/outlet but the housing itself still passes the full 18 to 100 GPM range.

Ships with 100 mesh (~150 micron) polyester, the right starting point for most well water. For high-flow whole-house systems we usually recommend keeping 100 mesh - it catches sand, scale, and rust without choking the flow. If you see fine silt slipping through, step down to 140 or 200 mesh. On sprinkler/irrigation lines where you only care about big particles, step up to 60 or 24 mesh so you flush less often. Stainless steel screens are available for hot water or high-iron use.

Watch the clear sump. When sediment is visible at the bottom, open the 1/2" flush valve for 5 to 10 seconds. With the larger 2" housing and a high-flow system, most installations flush once a month or less. Heavy-sediment wells may need weekly flushing. We always recommend plumbing the flush valve into a drain line rather than catching with a bucket on the Large because of the higher discharge volume.

For most well water, yes. The 2" Rusco at 100 mesh catches everything down to ~150 microns, which covers sand, grit, scale, and softener resin. For very fine silt or clay, pair it with a downstream 20" Big Blue cartridge filter at 5 microns. The Rusco catches the heavy stuff and protects the cartridge from filling up too fast. This combo is what we install in most heavy-sediment whole-house systems.

Yes, this is one of its most common uses. Sprinkler heads are extremely sensitive to sand and scale, and the Large Rusco at 100 mesh protects them at flow rates that would clog most other filters. For drip irrigation we often suggest stepping down to 140 or 200 mesh. Plumb the flush line to an outdoor discharge so you can flush quickly during the irrigation season.

Yes. Water flows IN through one port, hits a vortex deflector and spins (centrifugal action), sediment drops into the clear sump, and filtered water exits the OUT port. The housing is marked with arrows. Mount with the sump pointing straight down so gravity settles the sediment and so you can flush it through the 1/2" valve at the base.

Yes. Rusco housings carry a manufacturer warranty against defects in materials and workmanship.
