    Help. Should there be a vent pipe after the boiler and before the pump.

    I think my heating system is sucking air in through vent pipe. My heating system is as follows, boiler, pump, motorised valves then I think the vent pipe is after these. Does this sound wrong. I've taken a picture but Iam having trouble uploading it. Thanks

    Can I tee into soil vent in loft?

    My stack appears to vent into the loft, presumably using an air admittance vent, as there are no odours coming from it until you lift off the vent. Can this just be teed into with a new branch waste pipe (inc. toilet and shower waste) or would I have to extend the pipe to the outside?

    Any reason to extend f+e vent until submerged?

    I'm guessing not. Looked like someone had put a compression coupler on it (it was already fine, terminating inside f+e) and stuck another bit of pipe almost reaching bottom of tank. What am I missing? Removed it.
