MacValve Waterless Traps

When Space is a Big Issue - MacValves are your solution

Self Closing - One Way

When installation space is an issue and traditional traps just don't fit, Abey's McAlpine MacValve Waterless Trap is the answer! The Benefits are endless:

* Can be fitted horizontally or vertically

* The membranes inside opens under water pressure to allow discharge to flow freely and then closes to form a seal to prevent foul odour or sewer gas from entering

* Perfect solution where traditional traps won't fit

* Can be used to take the discharge from a pressure relief valve on an unvented domestic hot water storage system

* MacValves have no water seat and can never dry out

* MacValves are not recommended for use with shower trays unless there is access for maintenance.
