McDonnell & Miller 347100 Strainer Basket Assembly

As an HVAC veteran, you know that a clogged feeder is the fastest way to a dry-firing boiler. The McDonnell & Miller 347100 Strainer Basket Assembly (Model SA101-38) is the exact OEM specifies for maintaining flow integrity in 47, 51, and 101-A Series boiler water feeders. This assembly features a precision 2-3/8 inch strainer length and rugged stainless steel construction to trap scale and sediment before they reach the critical feed valve cartridge.

Replacing a fouled SA101-38 basket during annual maintenance prevents the bypass-leaking and slow-feed issues common in older mechanical water feeders. This kit is a direct replacement for McDonnell & Miller 347100 and includes the necessary O-ring (Tetraseal) to ensure a gas-tight, no-leak seal on the valve body. Whether you are servicing a Series 51 makeup water feeder or a Series 47 low water cut-off, using genuine McDonnell & Miller parts ensures the timing and flow rates remain within factory spec for maximum boiler system protection. Simply use a 1/2-inch socket to drop the basket from the hex port and swap in this assembly for a reliable fix.

• OEM Compatibility: Specifically engineered for McDonnell & Miller 47, 51, 101, 247, and 551-S Series feeders.
• Superior Filtration: Heavy-duty 2-3/8" mesh basket captures debris that can damage valve cartridges.
• Complete Kit: Includes the 347100 strainer basket and the high-temp O-ring gasket for a complete seal.
• Durable Construction: Built with stainless steel to resist corrosion in harsh steam and hot water environments.

Does this assembly include the O-ring?
Yes, the SA101-38 includes the required Tetraseal O-ring (Part 324435) to prevent leaks at the connection point.

Will this work with the 101-A electrical water feeder?
Strictly speaking, yes. This is the direct replacement strainer for the 101-A Series, as well as the 51-HD and 47-2 series units.

How often should I replace the 347100 strainer?
Technicians should inspect the strainer annually. If the mesh is pitted, deformed, or impossible to clear of scale, a full strainer basket replacement is required to maintain proper GPM delivery.
