Soil ventilation pipe

[david25]

Hi, we are having our bathroom redesigned and fitted but have had mixed conversations about the soil ventilation pipe.

The pipe is boxed in plasterboard at the moment, and leads straight up to the loft and outside the roof.

One guy has said we could remove it all together because we are on the end of a row of houses plus he said all the houses only need one vent anyway.

The other guy said we could not remove it and we are stuck with it.

Any ideas on what to do?

Thanks,

David.

You can put a durgo valve on the pipe and cut it back to above the spill level of the highest outlet.
As long as a few of your neighbours still have soil vent pipes using Durgo valve or air admittance valve as they are called would be fine.

Thanks for your fast response.

The only problem is that we are getting a floating toilet with an S-Frame, but this needs to be moved over to the left, but the boxed-in soil vent is in the way, that's why we want it completely removed, if we cut it down to the spill level, it will still be in the way of the S-Frame.

There's 9 house's detached and we are the last in the street, we have 2 man hole covers in our garden, one for us and one for the rest of the house's as we are on the end.

Could we get away with removing the vent pipe altogether? as the other houses still have vent pipes sticking out their roofs?

Thanks

David.

What happens if they all subsequently decide to do the same as you, though? You'll get an instant anal prolapse, if you happen to be sitting on the bog at the same time as someone downstream flushes...

LOL - what a prospect!

If the OP fits one of those horrible wooden seats, then he would not be sitting there long enough to be at risk

Or, even worse, the clear acrylic ones with shells in...

I think they have starfish in them too - only not of the chocolate variety

keep the s.v.p. let it vent those stinking poisonous gasses to the outside.

i have witnessed problems that have occurred by installing a durgo on the only s.v.p. to a property.

each time water was discharged into a shower or basin waste, water in the trap would be agitated and the stench released.

the durgo was removed and the system vented back to the open air.

once above any waste inlets, the venting pipe can be reduced in diameter.
