"There are to many poor reviews of this product. Fortunately the positive ones are now catching up. I recently installed 3 of these under the same sink, on each of the outlets while tidying up a messy installation. Two of which went on to old strainers, and one that went onto a brand new one. I had absolutely no issues with any of them. My trick was to unpack them, unscrew the trap and add a small amount of silicone grease to the thread and o ring, and give them a firm nip by hand. They sealed perfectly and i had no leaking at all. But then again, none of us qualified engineers using these have had problems ;) ... I've had no trouble with any floplast gear i've had over the years. You've just got to know what you're doing."
"I have bought quite a few of these traps as they are telescopic which gives you the ability to place the trap where you need it up or down a few inch's which on a new fit is quite good but as a replacement part on an existing basin pipe work they are more than handy. They are easy to fit but one word of warning, make sure that the bottle part at the bottom is screwed up tight because sometimes out of the bag they are a little loose and will let by, not a bad thing by any means and easily rectified by a firm twist. Price wise these are a bargain, would I recommend this product well the answer to that is yes its that simple"
"Bought 2 of these. No problem fitting trap and no leaks. However 1 of them was a 40mm size even though it said 32mm on the bag label. Got it exchanged no problem but when they checked their stock 9 out of 12 were also wrongly labelled. So save yourself a return trip and check what size it actually is inside the bag before you leave the counter."
"Reading some of these reviews you would think this trap had problems it doesn't. It is most probably the user. Care needs to be taken with ensuring the sealing ring is in the right position and tighten ensuring it isn't cross threaded."
"This product is fine. The bottle thread leaks reported by others may be caused by the high friction on the thread. This results in a "juddery" effect when tightening which means that the seal might not be complete if you were in "mid judder" on tightening. One turn of PTFE tape on the threads will make for a very smooth tightening and a perfect seal every time."
"Looking for a telescopic bottle trap? Look no further - they simply don't come better than this. If this bottle trap was an animal it would be a great white shark. Looks great from all angles and the way the waste pipe slips so smoothly in to the compression connector it's an absolute pleasure to handle. I couldn't entertain the idea of shopping elsewhere knowing Screwfix offer this particular item of unquestionable quality. I'd buy a garageful if I thought I'd ever need another one, oh - and they'd all be telescopic of course!"
