SSL Valves are non-return valves for foul drainage. The Stop Silent Light is an inline non – return valve to prevent backflow in sewer systems and pipework. We stock Stop Silent Light Valves for 100mm, 110mm & 150mm pipework. For 100mm raw sewage foul applications we recommend using the 110mm Stop Silent Light Valve.
Besides the backflow preventing function of the valve, Stop Silent Light furthermore serves as a flap-gate, preventing small animals from entering into pipe systems. A third function that gives the valve a competitive advantage is the airtight odour barrier, preventing channel gases from flowing back into premises.
