The Groco ARG-2000-S is a bronze raw water strainer with 2 inch NPT ports, standing 13-1/32 inches tall, with a stainless basket. It has no tie rods or gaskets, with O-rings sealing the mating surfaces. The retainer cap screws on for tool-free basket cleaning, and a mounting system with a reusable strap lets you take the whole strainer off without tools. The screen to pipe area ratio is 14:1.
Our take
The retainer cap screws on and off without tools, so clearing the stainless basket is a hands-only job, and with O-rings instead of gaskets or tie rods there is less to reseal afterwards. The 14:1 screen to pipe area ratio gives the basket generous area.
From our buying guide
Makers disagree on where to mount a strainer: Groco's installation sheet recommends above the waterline, and Westerbeke's generator manual says at or below it. Perko says to consult the engine manual for pipe size and strainer location.
Check before you buy:
- It matches your pipe size, since Perko says reducers may cause engine damage and are not recommended.
- You can reach the basket, since Groco says to inspect and clean it frequently.
- Open-area figures are compared within one maker, since each states its own measure.
