Product Description
Flexseal’s range of retrofit Non-Return Valves (NRV’s) can be installed directly into existing manholes by simply pushing the NRV into the desired pipe inlet. The product prevents foul water flowing back from the blocked sewerage systems to flood the property from the inside via toilets, plug holes and waste pipes.
The Retrofit NRV’s can be fitted in minutes and do not require any specialist expertise or equipment.
