Hey.
I've to a couple of hardware/DIY stores today and neither had pvc piping. I'm looking for piping, ball valves, connectors, that kinda stuff for an air rifle project. Does anyone know which UK hardware shops usually have this stuff? Homebase, B&Q? Looking on their websites doesn't seem to help.
Cheers
I bought lots of PVC pipe from B&Q For a Halloween fog projest, So yes they have it there.
Thanks.. Hopefully I can find somewhere nearer though, B&Q is an hour and a half away. Yuck.
I'm starting to consider copper pipes now.. how are they usually fitted together, are they threaded?
Copper pipes are usually welded, Although you can use a cutoff valve to connect them.

Also handle a lot more pressure

I would recommend it for an airsoft gun, instead of PVC.

They are not welded. They are brazed together, much cheaper, totally different setup. You only need a standard blowtorch, some flux paste and dependant on the fitting of the pipe joints, some copper brazing rod (some joints come with the copper already inside and just need a thorough fluxing.
If you want a rough how to guide you can google it or I can give you a step by step tomorrow.

Really? In Canada, you put the pieces together after your brush them clean, then put flux on them, and you solder them together. That way sounds easier.
I'm also surprised of the lack of PVC pipe in the UK from what it sounds like. You can go to any hardware store here and you've got lengths upon lengths of it.

PVC still isn't used in a lot of countries. It's cheaper, but it's got some adverse health effects to it. Hence why they have to dump extra chlorine and shit into our public water supplies.

Well, here it's primarily used for running vacuum lines throughout your house to the central vacuum unit or for irrigation of plants in indoor environments (dope growers love to use it apparently).

dont you mean solder?

The process is similar except a metal filler and higher temperatures are used.
Copper pipes can be soldered as well however the joint is usually not as strong.

Soldered joints would be unlikely to survive the pressures involved in his project I suspect.

For plumbing usage typically copper is soldered using a tin+other food grade mixture soldier. for HVAC applications, copper pipes are almost always all brazed using the copper brazing rod.

i mean what's the max psi he'll be looking at here? 100? or is it more?
Max PSI is somewhere in the region of 100-200, should be fine with pvc but I may have to go with copper just because the parts are easier to find.
Not sure I have the right gear to connect it all up, though.
Also while I'm posting, could anyone briefly explain how sprinkler valves work?
AFAIK PVC isn't really used, that i have worked with, to hold pressure. it's mostly used in draining applications only, what ive seen.
