I’ve been at this property for 22 years, and I have just notice I don’t vent pipe [ it goes straight into the manhole ] or any valves on my toilet system. I have never had any issues such as smells drainage or odours. It’s a ground floor toilet and the only one in the property. I’ve attach a picture hopefully this would help. The only vent is the 50mm waste pipe which sealed into the soil pipe, it's fixed 3ft on the outside devided garden wall. Is this sufficient

Regards

there was probably a durgo valve on the end of the 50mm and got thrown when jambed long ago?
the drain is still vented though, depends on smell!

Hi Redsaw
Thanks for you reply. What will a 50mm a Air Admittance Valve do

kind regards

Hi Redsaw

The Air Admittance Valve can be fitted outside the pipe going up my garden wall ?

stops any smells and rats coming out or anything getting in, just pop it on or leave it if its no problem
