175C U-Gauge (Manometer)

The Monument 175C U-Gauge (also known as a Manometer) should be used to test for leaks after installation or repair of any drain or pipeline system. Made from unbreakable parts, it will test up to 100mm (4in) water gauge pressure irrespective of pipe diameter. The hinged lid of the gauge folds back so that it forms a base behind the gauge for added stability.
