Sources for two odd components?

Question

Hi,Bit of a loss here - after much searching.I need:2 x 135degree 82mm solvent weld offset bends in black, or an equivalent wayto get an 82mm sewer vent pipe out and around a gutter (160mm lateraloffset needed). Don't really want pushfit, as there's be 900mm of pipewobbling around on top, unsupported, save for the support it can get fromthe lower section (bolted to wall).Also, I would like a "runner" u-trap in 40mm - that's one that can bemounted mid section, rather than having one end terminate to a sink. Thisis for a shared appliance trap servicing two[1] appliance stand pipes.[1] Or more likely one, as after the house is finished the washing machinewill move to be replaced by a freezer. One trap avoids having the redundanttrap dry out due to lack of use and will be plenty adequate. The idea is tohave the trap under the stairs for easier access (rather than pull machineout) and tee two standpipes of this.I briefly saw a mention of a runner trap weeks ago and being an idiot,forgot to save a reference!TaTim

What are you measuring to get 82mm and do you really mean 82mm? I would expect a sewer vent pipe to be 4 inch - plastic pipe is measured by the bore in inches and 4" would be about 115mm OD. Three inch pipe would be 89mm OD while 2.5 inch pipe would be 73mm OD. 82mm is not a dimension I recognise.

Yep - I mean 82mm - that's the quoted size (aka 3" I guess) - it's the nomenclature used by Hunter Plastics. Sewer vent pipes must be >=75mm ID according to building regs, hence choice of pipe. 110 is unnecessarily big to dangle up the side of a building when the sole purpose is to vent the local drain run.

Incidentally - I've always heard the modern 4" referred to as "110" not "115".

I've not seen anyone else use that size, but it is pushfit and each manufacturer has their own ideas about pushfit sizes. I rather doubt you will find a solvent weld connection to suit a pushfit pipe In some cases, depending upon material, pushfit pipe may not solvent weld at all..

4" is the common choice, because that usually is easier to match to the underground pipes . You could use a standard 89mm OD 3" pipe instead, which would have the connectors you want.

It should still be referred to as 4 inch, but, as many people today have never used inches, millimetres have become popular in retail based businesses. The OD of a BS PVC pipe is near enough 115mm, whatever the retail trade decides to call it. The size is set by the need to be able to cut a 4" BSP thread on it.

Guttering places seem to be the best online places for this stuff - I think it's also used for large capacity gutters.

for example. You'd need a 112 degree offset bend and a 112 bottom offset bend.

Our local plumbers' merchants also sell a reasonable range because it's quite common for soil pipes around here. Last place I got an odd component from was Burnley Plumbing Supplies, who also sell on eBay, so they would probably do mail order.

I think I almost found one. Diagram looks right, but the diagrams are often wrong.

As it happens whilst I was waiting for BES to answer the phone, google turned up with:

who do a range of very interesting oddball fittings, many of which I have not seen elsewhere. Ordered what I needed.

Quick call confirmed they were uPVC and waste pipe grade. Guess they sell them for interconnecting fish farm ponds and tanks and stuff.
