Lamprey Hardware 2" Winter Plug with Schrader Valve for 2" Pipe — LHBP11, Reusable Blow‑Thru Seal

The Lamprey Hardware #11 Winter Plug (LHBP11) is a blow‑through open‑stem plug with a Schrader valve designed to seal and pressurize 2" pipes for winterizing, pressure testing, and clearing line blockages.

This durable plumbing accessory from Lamprey Hardware fits 2‑inch lines and combines a secure rubber sealing plug with a built‑in Schrader valve to let you add or release air or water pressure easily. Tradespeople, pool technicians, and homeowners use it to isolate sections of piping, push out water for winter storage, confirm system integrity, and assist in unblocking pipelines. The LHBP11 is compact, reusable, and engineered for repeated field use where a reliable temporary seal is required.

How does the LHBP11 help when preparing pipes for winter?

The LHBP11 lets you isolate a 2" section and apply pressure or air to evacuate residual water, reducing the risk of freeze damage. Because it’s an open‑stem (blow‑through) design with a Schrader valve, you can attach a pump or compressor without removing the plug.

• Creates a temporary, leak‑resistant seal inside 2" pipe.
• Allows controlled blow‑out through the stem to clear water.
• Schrader valve enables easy connection to pumps and gauges.

Can I use this plug to pressure test or diagnose leaks?

Yes — the LHBP11 is suitable for pressure checks on 2" lines. Its secure seating and valve let you pressurize the isolated section and monitor for pressure loss to identify leaks or weak points.

• Quick seat-and-test action for field diagnostics.
• Compatible with standard pressure gauges and compressors.
• Reusable for multiple test cycles when handled properly.

What kinds of systems and fixtures is it compatible with?

The #11 blow‑thru plug is designed for 2" diameter pipes and works across a range of applications: pools and spas, pumps and motors, sinks, showers, and general plumbing runs. Its open‑stem style makes it useful whenever you need to either vent, blow out, or pressurize a line without permanent fittings.

• Ideal for pool and spa plumbing during winterization.
• Useful for household drains, shower lines, and utility piping.
• Handy for service techs performing maintenance or unblocking lines.

How should I install and maintain the LHBP11 for best results?

Installation is simple: select the correct plug for a 2" bore, push the plug into the pipe until it seats, then use the Schrader valve to apply or release pressure. After use, rinse any debris, inspect the sealing surface, and store in a dry place to extend service life.

• Press in evenly until the rubber lip forms a tight seal.
• Attach pump or gauge to the Schrader valve for controlled pressurization.
• Clean and inspect the plug after each use to maintain sealing integrity.
