Executive Summary: Are there two different sizes of solvent weld, 22mm and 21.5mm and if so how do I join them?
Hello,
My cold water tank relocation project is going well, and has now reached the final stage of reconnecting the overflow pipe which seems to be made of the normal white PVC solvent weld stuff. Since the tank is now closer to the wall than when I started I have plenty of spare pipe. I also have a miscellaneous collection of joining pieces, mostly from Screwfix.
The problem is that no matter how I try I cannot get the pipe into the joints. I seem to remember that last time I did solvent weld it was all very easy. Now, looking closely at the pipe I see that it says on the side "Marley Extrusions 22mm UPVC Overflow" whilst looking at my Screwfix joining pieces they all say 21.5mm. Has the industry really managed to produce overflow pipes in two almost identical but incompatible sizes, or are these are so close as to really be the same size and if I was a big burly plumber as opposed to a feeble wimp of a scientist I could just shove them together?
For reference, my house was built in 1990.
Should I just file the end of the pipe down until it fits? Should I put my back into it and stop complaining? Can I buy 22mm fittings from somewhere? Does anyone make an adapter? Should I just rip out all the 22mm and re-do the whole job in 21.5mm?
Thanks
