Infiltration & Inflow prevention and datalogging
Thursday 23 August, 2018
Rainstopper Manhole Inserts prevent 98% of stormwater entering the manhole by providing a positive barrier between manhole frames and covers, thus sealing “the invisible gaps”. The Rainstopper is easy to install & remove and is maintenance-free. Manufactured from 304-Stainless Steel, the Rainstopper can suit any manhole shape and size. Alternatives such as applying grease and rubber gaskets are subject to a careful installation and maintenance as frames and covers need to be re-greased often and rubber gaskets can easily dislodge/move when the lid is slid back on and can raise the manhole cover to tripping high levels.
