waste pipe spec for household sinks

[steveo3002]

ive measure up some waste pipe as 41mm o.d

this doesnt state i.d or o.d ....does this sound like what i need, assume its all standard?

it states 40mm so that is its outside diameter

becareful with waste pipes not all are the same and also goes for the colour of the waste pipes

most diy places use different spec pipes osma as i call them

then you have glued pipe and then you have polypipe

 

[steveo3002]

yeah isnt helping the local diy places have no stock showing , only need a elbow and a meter of pipe over the drain outside

 

[dobbslc]

"Normal" sizes are 32 and 40mm the one you've shown is push fit and as far as I know that's different to solvent weld or compression types.
What sort of fittings are you connecting to?
Pipe sizes in plumbing are so arcane, probably going back centuries, it's the reason I have bags of unused wrong sized fittings in the workshop!

 

[gaz1]

look for solvent weld pipe

 

[steveo3002]

solvent = superglue? or do i need to spend on that too?

push fit a no no then?

 

[dobbslc]

It's not super glue.

Show us the fitting / pipe its going on.

 

[steveo3002]

im not with it at the moment ...just a plastic pipe that measures 41mm o.d

so 40mm solvent vs 40mm push fit isnt the same pipe?

just buy a new pipe going into the property as well if your only going to your sink drain with an elbow

thats because some idiot used this

as goes for old fittings had enough of them @dobbslc mine went in the bin saves finding them when replacing them with new is better

nothings easy is it ...bit of silicone in the gap i recon lol

 

[jack-daniels]

I think these compression fittings will fit all pipe types.

[gaz1]

nah just buy a compression straight waste pipe it will do it

same with elbow same with the connection to sinks and bath waste

 

[steveo3002]

was in two minds of asking what i felt was a silly question...glad i did now , always get sound help here cheers all

 

[angellonewolf]

if theres not much there id replace the lot must only be a couple of bends and a p trap or s trap use the glue stuff if its compression fit or push fit by the time you start messing around with it there will lightly be leaks and chasing your tale

£30 buys you the glue and prob all the pipe work bends and trap all new looks nice and as its glued wont leak

when using the glue cut the pipe debur the ends a wipe of glue both sides that you want gluing fit and twist a little over 180 degrees and leave for a few mins

Solvent or compression makes a difference

 

[mike os]

Solvent and push fit are different sizes and you cant solvent weld pushfit

 

[angellonewolf]

as above the solvent stuff is i think the bigger of the lot but a trip to b and q to match up what you got with a screw on trap fitting

screwfix will be cheaper

Pushfit is usually 40-41mm od ie 1 1/2.
Solvent is bigger 43mm, if you put a good chamfer on solvent and are prepared for a battle it can be forced in.

A compression fitting will fit both sizes, if your going solvent I would recommend wet or dry solvent cement

It sets quick and I have never known it to fail, careful though it will melt lino.
