2xMonument 1290h Flexible Inflatable Plug 4in

Provided with a car-tyre valve, stated pressure limit of 1.5 bar (21psi), so best to use a tyre pump with a pressure gauge. Rubber inflation pipe 1.5m long, so can place, inflate and deflate in a MHC approx 1m deep without having to bodily enter chamber . I was able to fill a 400m deep pvc inspection chamber with water to flush outgoing drain, then deflate bung remotely, without then losing bung in ensuing water flow !

Great just what wanted for blocking outlets on gutter and then fill them to test , only thing is should be offered with a small had pump , that can use when on a ladder ,

it is for testing drainage pipework

Very good, tough, inflatable drain plug. Half the price of builders merchants. I'll be using this product for years to come!
