3/4 inch T-451 Swing Check Valve

The Legend Valve 105-104 is a brass swing check valve designed for plumbing systems requiring one-way flow control. It suits installers and maintenance teams fitting or replacing inline components in residential or light commercial pipework.

Brass body under continuous pressure

The brass construction resists corrosion during sustained exposure to water and typical plumbing fluids. The swing disc opens with forward flow and seats firmly when pressure equalises or reverses, preventing backflow without external power or control signals.

Replaces worn swing check valves

This unit fits existing 3/4 inch lines where a failed or leaking check valve allows reverse flow or water hammer. The upgrade is worth it when the original seal no longer holds or the hinge mechanism sticks, restoring reliable directional control.

Questions about this item

How much heat does the 3/4" T-451 brass swing check valve generate during continuous operation?

This is a passive mechanical valve with no electrical components, so it produces no heat while water flows through it.

What piping or fittings must I already have to install the 3/4" T-451 check valve?

You need a 3/4-inch threaded pipe or adapter on each side to match the valve's female NPT connections.

Will the T-451 check valve work with older galvanised or copper pipe already in the system?

Yes, the brass body threads onto standard 3/4-inch NPT threads found on both galvanised and copper piping.
