What it is
The Andrews 3/4 NPT pipe plug is a brass threaded plug used to blank off a 3/4 NPT port on Andrews water heating appliances. It seals the opening against water or system pressure, and is removed when the port is needed for a drain, sensor or connection point. It is listed by Andrews under part number 7721605.
Signs this part needs replacing
- Water weeping or tracking from around the plug threads
- Visible corrosion, verdigris or pitting on the brass body
- Rounded or chewed hex head that will not take a spanner cleanly
- Crossed or flattened threads preventing a pressure-tight seal
- Scale or sealant build-up on the threads after repeated removal
Before you order
- Confirm the port on your appliance is 3/4 NPT before ordering
- Check the appliance model against the manufacturer's parts list to confirm 7721605 is the correct plug
- Inspect the mating port threads for damage, as a worn port will not seal with a new plug
- Have a suitable thread sealant to hand if the plug is being fitted into a pressurised port
