Browse Forums Bathrooms and Laundry 1 Dec 04, 2012 8:22 pm Was having a look at a house to buy the other day, built in the mid to late 70's and saw a toilet vent like nothing I have seen before. Basically if you are looking at the toilet there is a pipe coming out of the S bend at about 45' which then heads into the side wall. Am curious as to when and why this type of venting is used. Also if I were to buy the house and renovate how much of a pin in the bum (and hence cost to me) is it to change the vent to one that is hidden? The floor under the toilet is cement slab but frankly as the toilet is well off centre I would want to centralise it anyway. Re: Odd Toilet Vent 2Dec 06, 2012 10:00 am From memory a vent is installed between the last water fitting and the toilet so waste from a downstream surge doesn't lead to water being sucked out of the toilet leading to sewer smells escaping into your rooms. The plumbers have probably installed the vent this way because of a similar problem they have encountered. You could probably get a plumber in to replace the existing vent pipe to one on the outside wall instead. Photos showing the vent pipe and wall immediately outside the toilet would help too.

Stewie Thanks for replying. Don't have pics because it isn't my house, was just looking at it and trying to work out if it is worth buying. Certainly needs bringing up to scratch so figuring out how much it's going to cost, roughly to factor that into any bid. The bathroom, toilet and ensuite all need doing, and due to what I imagine will be asbestos walls will need gutting completly and of course removed by a licenced asbestos remover. With the toilet I should have mentioned it is not on an outside wall it is in the middle of the house. The house is actually a split level with the back wall of the toilet backing onto the split, with the toilet on the upper side. The main bathroom is to the left which is the way the vent pipe goes, with the shower on the other side of the wall. What I was hoping is it wouldn't be hard to dig up the slab where the toilet and the shower are and put the vent through the joining wall but from within the slab rather than coming from the top of the S bend of the toilet as it looks awaful, and as mentioned the toilet is well off centre which also looks awful. Just tried to look for some pics of somthing similar but cannot find one. Re: Odd Toilet Vent 4Dec 08, 2012 7:25 am Ive seen these toilets before. They are used to comply to codes where the vent must be within certain distances from the fixture. It may have been easier to vent this way than tie into a 3inch wet vent in the wall, but it is ugly. I saw them used in a campsite with about 5 toilets all vented with side side vents and a studa vent used in each one. If you used a standard toilet you may have problems such a siphoning or gurgling from the water in the trap when another fixture is draining, or it maybe fine! These codes can vary so much that sometimes things are over vented just because one code says it needs it and another says its fine. Or the plumber just put it in because he thought he should! How do you remove one of these ceiling air con vents? And is it possible to disconnect the duct joined to the vent from inside the house, without going into the roof cavity? 0 5947 Looking at some of the designs on websites, they are all selling very similar products.
