Summary

X-Pipe fitting for connecting 4 Ø22mm Pipes.

Generation 3 (Gen3) of the Southern Pipe Fitting Method. More Updates to follow.

I could make one of these, certify it to all the standards, and be 100% confident that it is safe. But that would be mine, printed on my printer, acetone vapour bathed in my coffee machine, not yours.

I can't vouch for the quality of your build. That's something you'll have to do.

Ok, I've not seen anyone do plumbing or pipework of practical use, so I'm claiming this as the modestly named Southern Method. Using a single material home printer and Printing the pipes at 45° WITHOUT SUPPORT MATERIAL to print bed allows finished pipe profiles to be round rather than "teardrops" shapes to prevent the materials collapsing in on itself at the top.

Note: This Version of the Pipe Fitting has an unsupported roof so I used the Teardrop profile in a very small area on the central cavity. (See X-Sec).

First rule of plumbing club, you don't mess with systems you don't understand.

Every modification will take as long as it takes.
1 system per mod,
If this is your first night at Plumbing Club, you've got to plumb.

This is intended for low pressure return pipes for grey water at approximately room temperature. Do not use on Gas (Propane, LPG, Butane, Domestic Gas supplies, or any combustable media). Do not use on hot water or central heating systems (temp >40°C ; If you do not understand what ">" or "°C" means, don't use this part!). Do not use on macerated sewage. Do not use in temps close to 0°C. Do not use under floorboards or similar situations where it cannot be seen, monitored or changed easily. This design is not suitable for use in Nuclear Power Stations or Satellite Applications.

Basically, use this sensibly. I've used similar in hydroponics, and it works at low pressure (102KPa / 1ATM - if you don't know what a KPa is, or what 1 ATM is, please don't use this design).

I'm saying "Grey Water Systems Only" - but that's an ass covering statement, if you feel your build is safe enough to use on other systems, I'm not your keeper. I'm just an idiot.

This is based on previous design
