No-Lead Brass Boiler Drain Valve
The Legend Valve 107-144NL is a 3/4 T-521 no-lead brass boiler drain valve designed for plumbing systems requiring lead-free components. It serves installers and maintenance teams working on hot-water boilers or hydronic heating loops where a reliable drain point is required. The valve meets no-lead brass standards for potable-water safety.
Sustained Load Behaviour
Under continuous system pressure the brass body and stem resist deformation and maintain seal integrity over repeated open-close cycles. The no-lead alloy avoids the stress-corrosion risks associated with traditional leaded brass in high-temperature water service. Thread engagement remains consistent during thermal expansion and contraction.
Practical Interface Limits
The 3/4 T-521 thread pattern fits standard boiler drain ports but will not mate with finer-pitch or tapered-pipe threads without an adapter. California Proposition 65 warnings apply as the product contains chemicals known to cause cancer and reproductive harm. Installers must verify local code acceptance for no-lead brass before use.

Questions about this item
Does the 107-144NL valve generate noise, heat or draw power when left open all day?
The 107-144NL is a passive brass drain valve with no moving electrical parts, so it produces no noise, no heat and draws zero power during continuous operation.
What piping or fittings must I already have to install the 3/4 T-521 boiler drain?
You need a 3/4-inch female threaded connection on the boiler or pipework and compatible thread sealant or tape to join the valve's male 3/4 T-521 outlet.
Will the no-lead brass 107-144NL corrode faster when paired with older standard-brass fittings in my system?
The no-lead brass body is galvanically similar to traditional brass, so mixing it with existing standard-brass components does not accelerate corrosion in typical hydronic systems.
