Im in the uk maybe your ideas are different in the usa. We dont vent every waste pipe as there is no need.
every fixture needs to be vented, by code, its pretty standard, im sure in the UK your pipes or fixtures are not so different that you dont need to vent them, wether you like it or not you need to vent every fixture. if its to far away from the main stack, then it needs its own separate vent tied in as well. sucks when sinks and showers make all kinds of funny noises, bubbling and you wonder why…. (aside from keeping traps full of water of course..)
wow… great info here guys! I’m in my 2nd semester of L.A Trade tech Plumbing. This semester is all codes! I actually understood a bit. Since I studied ch. 1 a week ago In the U.P.C book. thanks ask the builder,I will watch all your videos! best,Jeff
Study hard Jeff as we need great plumbers out there. It’s a great vocation.
the u.k???
thu u.k has some of the worst plumbing in the world…
if you want it done properly… follow Australian Standards…
it’s a 6 year course done here… plumbing, drainage and gas fitting.
we don’t muck around… we’ve done all the science
well done.
Yeah, you Aussies probably lead the way in plumbing. Everyone’s got to find their level. Don’t forget that you’re mostly descended from convicts, and the plumbing techniques were first pioneered by Brits and Europeans. G’day Sport!
why not just use a cheater vent aka island vent? and before the comments start I am as well a master plumber and I have never had an inspector complain about it as long as it was only serving one fixture
In this case it was so easy to tie into the existing vent line. The biggest problem with mechanical vents is they can fail. Traditional vents work all the time unless some idiot drops a tennis ball down the roof pipe. I’ve installed mechanical vents in an island sink and they are suitable, but no real long-term substitute for a traditional gravity vent. Your mileage may vary.
that 15mm copper pipe in the stud could hav been clipped better, wouldnt be suprised if there was a bit of water hammer
Thanks for the suggestion. No water hammer at all in this installation. If you want to know the *real* reasons for water hammer, I urge you to go to my website and read all my past columns on this topic. You might be really surprised as to the cause.
convert the copper to pex
Yea its so good that you have spiders and snakes living in your pipe lines ready to come up and bite your ass.
andrey162000 , im not talking about the usa, and if you dont live in the uk or plumb in the uk then dont comment as yours is different. and if you read my comment i already said the pipes need venting if they are long runs,
I think it’s a bit misleading saying that the plumbing code requires that the vent pipe connection to be “right about here” since the connection can be made anywhere higher than original “problematic” location.
Thanks for the comment. Sounds like you know a little bit about the topic. I went to your channel and not one plumbing video. How about you take the time to share your plumbing knowledge via some videos?????? Focus your energy on videos rather than the keyboard. :->
You are right, that little flapper and spring will eventually wear out leaving you with a sewer smell. Some states they are illegal. In ilinois mechanical vents are against code.
if i tap into an exsisting vented sink drain do I still have to vent the new sink?
Yes. Furthermore, you need to make sure that sink stack can handle the extra fixture load. Don’t know what that means? Look it up or call in a pro.
Just a side note to all you weekend warriors…don’t run 1 1/2″ vent pipe through 2″ x 4″ studs on a load bearing wall. In this video, he doesn’t have to worry about it, but be careful esp. when working on exterior walls.
Thanks for the comment. The only thing missing from it is the exception where it’s fine to do if you then add the code-approved Simpson Strong-Tie metal wraps that compensate for the lost wood.
our local inspectors from my home town wont even talk to you ..unless you give them a 30 pack………boozbags
My plumber from Lakeland, Florida just glued the PVC and one month later my master bed room and my guest bathroom were flooded damaging the entire floor, wall, wasting all my brand new tile/laminate floor and walls as well as all the bath attachments. They never came back to fix it. They were Polk County school board worker.
Maybe he’s that smart plumber that get’s payed to fix plumbing as opposed to teaching others to Do it Themselves. As I have no clue about plumbing besides shit runs down hill and air pushs it through, I appreciate your videos, but respect that other plumbers dont make them!
There are plenty of plumber picture books to get the right idea.
Here in Asia, they don’t even know what a close system means and venting.
They are catching up on technology but way behind in plumbing standards.
Lousy plumbing a supplies, i guess they copied Europe too much.
