House Mods 3/4" MNPT Water Heater Drain/Flush Valve HMP011 — Lead-Free Brass, 3" Shank, Full-Port 3/4"

House Mods HMP011 is a lead-free, full-port 3/4" MNPT ball valve with a 3" shank designed to quickly drain and flush water heaters while fitting ports up to 2-1/2" below the surface.

Built for reliable, heavy-duty service, this HMP011 drain/flush valve combines a lead-free brass body with a 304 stainless steel ball and a full 3/4" flow bore to move water and debris fast. The extended 3" shank reaches deeper heater outlets, and the large octagon nut and handle make installation and operation straightforward for homeowners, plumbers, and maintenance techs. A garden-hose-ready cap, 180° handle travel, and included thread tape round out the package.

How does the HMP011 speed up flushing and routine draining?

The HMP011 uses a true full-port 3/4" bore to maximize flow and reduce clogging during flush or drain operations. That larger opening clears sediment and debris more quickly than narrower valves, so maintenance takes less time and effort.

• Full-port 3/4" (19 mm) bore for fast water flow.
• 304 stainless steel ball resists corrosion and debris binding.
• Garden-hose-cap-ready outlet for simple hose attachment.
• Large handle offers positive control while draining.

Will the valve fit my water heater drain opening and how deep can it reach?

This model has a 3" shank designed to reach drain ports up to 2-1/2" below the heater surface, providing secure seating and leak-free performance where shorter valves fall short. If your heater has a shallower port, the manufacturer offers a 2" shank alternative (model HMP010).

• 3" shank fits ports up to 2-1/2" below the surface.
• 3/4" MNPT threaded connection matches standard heater outlets.
• Large octagon nut simplifies wrench installation without deforming fittings.

Is this HMP011 safe for potable water and durable for long-term use?

The valve uses a lead-free-compliant brass body and a 304 stainless steel ball, meeting suitability for potable water systems while resisting corrosion. Its heavy-duty construction and substantial net weight give it the durability expected for regular maintenance cycles.

• Lead-free-compliant brass body suitable for drinking water systems.
• 304 stainless steel ball for corrosion resistance and wear life.
• Heavy-duty build (net weight ~17 oz) for reliable handling.

How easy is the HMP011 to install and operate in tight spaces?

Installation is simplified by the large octagon nut, allowing a secure fit with a pipe wrench while minimizing the risk of overtightening. The generous handle and 180° travel make opening and closing the valve intuitive, but you should confirm adequate clearance around the heater before fitting.

• Large octagon nut for easy wrench contact and torque control.
• Large handle with 180° rotation for flexible placement and simple operation.
• Includes garden hose cap and thread tape to help ensure leak-free setup.

Who is this for? The House Mods HMP011 is intended for homeowners, plumbers, and facility maintenance staff who need a dependable, high-flow drain/flush valve for water heaters—especially when the heater’s drain port sits deeper than average. It’s a practical upgrade for anyone replacing a worn or undersized valve or installing new equipment that requires a longer shank and full-port flow. Not suitable for installations subject to freezing conditions; select appropriate winterization measures in cold climates.
