    Anti Syphon trap?
    I'm looking to have a new bathroom fitted and had a plumber round to give me a quote.
    I want to fit a shower cubicle next to the bath and as the waste pipes are going into one the plumber told me he can't do this as every time I emptied the sink it would open the seal. Is this correct and is there any way round it.

    I've been told about an Anti syphon trap which would stop the smells and water coming back up. Is this correct? If so, I presume its no harder to fit that a normal fitting.

    Please help

    I had a bathroom sink that I moved a few years ago to a new location. I could not install a proper vent at the new location. I purchased and installed an anti-syphon vent (this was in Canada and we did not have a trap / anti-syphon vent combo) on the sink drain. It worked quite well. Of course a proper vent connected to your system would be the best method, but there are times when this cannot be installed for a reasonable cost, hence the anti-syphon vent was invented (pun intended). A quick search on the net showed me that you can purchase a "P" trap / vent combo. The vent I installed had threads on one end. This required an application of teflon tape to "seal" the threads and prevent water or gases from leaking into the room. After you install the vent, monitor the room for sewer gas smell. Your nose will tell you if your vent is leaking gases. A small pool of water under the vent will show that water is leaking as well.
