The Drainstopper
The DrainstopperTM offers a cost effective solution to low risk receptors.
The DrainstopperTM successfully combines a durable bladder system which can be installed in-situ with no need for Confined Space training. Our hanging bracket system, which extends up to 3m, is installed at the top of the man-hole, and allows the Bladder to simply swing into the inlet/outlet on installation.
This patented technology means that maintenance is no longer a specialist job as the bracket can be lifted and placed back into the hole with ease and simplicity, all from above ground.
The DrainstopperTM system is fully automated, with a control panel which stands next to, or near to the locality of the manhole where the Bladder is situated. The DrainstopperTM system can use Bladders ranging from 4” to 24”, as pressures are properly regulated from the control panel.
Presenting the end user with choice and flexibility, the control panel can be operated by mains electric, or a solar panel, which can be as small as 10W. The solar option allows use of the DrainstopperTM in hard to reach sites, or in locations where it is not cost-effective to run mains power to.
The DrainstopperTM can be activated manually via a push button on the control panel, which inflates the bladder in the man-hole, quickly, and effectively. Once inflated, you can properly deal with the situation in hand, without worry of a pollution incident occurring.
