compression

I can’t work out which compression elbow has been used. I’ve only removed the sink waste elbow, but it revealed a 45mm pipe - 1 3/4 inch-ish I guess. All I I can find, though, are McAlpine ISO 1 1/4”, 1 1/2” and 2” elbows. I’m a bit stumped, to be honest. Any help would be appreciated. Thanks.

I note on John guest’s website that they state that their connectors can be used with compression joints as long as they are not shallow depth. It’s a a subjective statement and I’m not sure whether it will be OK in my scenario with the iso-valve i have purchased. The attached pictures show...

Trying to replace a Bristan basin mixer tap - bought a new one which has the usual screw-in-at tap-end tails with the captive spinning nut on the end. When I came to remove the old one, the pipe connections appear to be compression fittings, and I can’t reuse the existing tails because they’re...

Right next to my shower tray there is a 110 mm soil pipe and i need to feed-in the 40mm waste pipe. Being in a recess, once it is connected up it is virtually inaccessible without taking the tray back out again. :-/ My question relates to the best type of reducer to go with i.e. solvent weld or...

I purchased a second hand Chainsaw ms 261. it start at first pull and accelerate just fine. I checked compression and seems to be only 125PSI when usually is over 170psi when new Would you just leave everything as it and keep using or should I replace piston/rings or just rings? Any advise?

Does anyone know the compression (PSI) for the stihl engine when they are new condition? Going to view a professional chainsaw which they say does not work and only fuel needed. Sound strange as everyone can put fuel and try. Got compression reading tool and if allowed can try but not sure what...

I have some 8mm tails that need extending to the rad. Would it be of any benefit if I continued them to the rad valves with 10mm?

Is it ok? What's it like to solder? Can I put a compression fitting on it?

One side of my mixer tap suddenly stopped working - fine yesterday, nothing today. I'm guessing that either a washer has perished or I've overtightened and damaged the olive. I can't see what the actual problem is because I can't get the head gear off. I've removed the cover, but the head gear...

We are having a gas hob installed by a gas safe plumber on a labour only basis and I need to source something to connect to the 1/2" male thread on the hob to the pipework. I was under the impression that any 1/2" female fitting that will join to 15mm copper by solder or compression fitting...

Without getting into complex engineering calculations, how can I make a reasonable assessment of the max compression load for an approx 2 M length of mild steel single angle 7mm thick and 80 mm each side. I would like to use it as a mid span "post" to give additional support to what appears to...

Hi I just purchased a 3 way tap that came with 1/2" flexi hoses for each of the 3 holes. 1 hose is for the hot water and 1 is for the cold water. The 3rd one is for the filtered water. I am using an undersink water filter system that connects to a tap via a 1/4" plastic tubing. How on earth do...

I've been looking online at a new sink base unit that's listed as having a 40mm void to it's rear? Is it 40mm, or is it actually larger in order to accommodate the compression connections etc? My existing sink waste pipe is slightly over 40mm anyway, with the various connectors being...
