Browse Forums Bathrooms and Laundry 1 Nov 04, 2010 5:23 pm Hi, Doing a new extension and the builder company who set up the plumbing in my bathroom in their greatest wisdom ran the pipes through the floor for the vanity unit. Now this would be fine if I have a standard floor vanity, however I have a WALL HUNG vanity unit. When I approached my site manager that it should be in the wall, he said that it couldn't be done? I think he said something about the timber integrity or something would be comprimised. Whats the real deal? Can the pipe be done through the wall? so I don't have a pipe running through the bottom of my vanity? and he's ****** and making excuses? Regards Re: Plumbing second opnion and advise 2Nov 04, 2010 6:54 pm Are we talking water supply or drainage? If drainage then the pipe diameter is 50mm or 40mm. Assuming the stud wall is 90mm then water supply can penetrate the stud no problems they are only 15mm. Drainage would breach the standards or building code if 50mm and at 40mm might be possible but not ideal. As a side point 40mm is never my choice for drainage. Good Luck Pulpo Re: Plumbing second opnion and advise 3Nov 04, 2010 7:41 pm Hi Pulpo, I'm talking about the water drainage. I've got to measure the pipe sizes and it is a 90mm stud wall. Although from memory I don't recall seeing any studs that the pipes needs to go through. From memory, its just open space in the wall. I'll have to double check but if there isn't any studs in the way, shouldn't it be fine? Thanks Re: Plumbing second opnion and advise 4Nov 05, 2010 7:33 pm Hi, Talked with the supervisor. He said that the pipes (drainage) needs to be run under the floor (second floor) and up through the timber (where the wall is) and that this would breach building integrity. Is this true? and if so, how on earth do they do plumbing in houses that have wall hung vanities? Your answers would be greatly appreciated.

I don't have a wall hung vanity, but my drain pipe still goes through the wall. For the record the wall is an internal wall with standard construction, built 10 years ago. So don't see why it would be a problem. As you said if they don't do it how would you ever have a wall hung vanity. Re: Plumbing second opnion and advise 6Nov 06, 2010 10:38 am He's ******. As a plumber, ive installed plenty of wall hung vanities and although, optimally it might be best to have the waste pipe running into the floor, there is no problem with running the 40mm waste pipe (its always 40mm for a vanity. 32mm isnt used any more) through the studwork. thats what hole saws are for. If he was worried about building integrity he could fit support studs around the penetrated studs. In reality, his plumber hasnt fitted the waste pipes in the wall before the wall cladding was installed and they dont want to pull the cladding off to do it. If there have been changes, variations, during construction then the drawings should be revised, the building permit amended and the current, as built drawings given to… 2 4480 Hi team, Im looking for a second hand sd4b monitor preferably white. 0 8923 We were lucky in that our old house was so small (86 square metres) compared to the new house, they were able to take enough readings around the old backyard house before… 8 37139 |
