soil and vent pipes

[mattsimmons]

hi

can i fit a soil and vent pipe without it going through the roof ,what are the buiding regs for putting a turn in a soil and vent pipe or does it have to be vertical ...as you may have geussed i am not a plumber

It does not have to go through the roof. I dont know the exact details. They would be in my old Water Reg's book. But you can put a swan neck (two 45's) on it.

Hope that makes sense.

Oh but the actual soil stack, must be verticle.

Hi I confirm Dannys post. You can reduce the vent pipe to 75 mm if needed, If through the roof is the only option use somethig like this = Pitched Slates | Lead Slates | Just Lead - Sheet Lead Products Good Luck

If it's going internally you can protrude it into the roof space (loft) and fit an air admittance valve that's if there's multiple appliances going into it. If it's for a couple of downstairs appliances (including WC) a stub stack will suffice.

stick a dergo on it google dergo/air admittance valves

make sure thisisnt the only air inlet on the sewage system from the property or else you will be causing potential drainage problems, as every stack should have at least one open outlet on it.
