75mm water seal features an adjustable inlet tubular swivel anti-syphon (Silentrap) 'P' trap with universal outlet. The anti-syphon valve neutralises negative symphonic pressure before it reaches the seal of the trap and therefore provides the equivalent of a ventilated system.
Adjustable inlet makes the trap suitable for all domestic repair, maintenance and improvement work. Universal compression outlet suits all plastic waste pipes, copper pipes and lead pipework. It features a Silentrap that will not unseal under high pressure or abnormal conditions, making it reliable and user-friendly.
