Reviews
Self Cutting Drain Off Cock 15mm is rated 3.4 out of 5 by 7.
Rated 5 out of 5 by from Easy to fit Excellent fix for seized or missing drain taps on a central heating system. Easy to use, zero skill required. Take some time to choose a convenient spot to attach a hose for draining, at a low point in the system. Remove paint from the pipe with sandpaper to get a good seal. Attach the clamp tightly and screw in the tap firmly and quickly. I had a moment of hesitation half way and water started squirting out bigtime causing panic. But continuing quickly saved the day and moments later it was done. 15 mins tops.

Rated 3 out of 5 by from Does the job, just A cheap way of draining a system but I chose not to leave it connected permanently as the quality is a bit pants. It seems to me made of finest Chinesium which looks like it would crack if slightly over tightened. SO DONT OVER TIGHTEN WHEN FITTING ! Otherwise worth using.

Rated 4 out of 5 by from Will it leak? Wanted something to drain a water system, and found this device. On the whole, it appears the ideal quick fix and easy solution, with no compression type being readily available. But what I found rather concerning, was the remarks about leakage, at a later stage. Which is something that I need to bear in mind for problems in the future perhaps! This 'self cutting' is nothing new, but you do need to consider the the amount of possible force required, and possible age of the existing pipework!.

Rated 1 out of 5 by from Didn't work well Used this as a temporary valve to drain the system so I could then fit a more permanent valve as the original one was seized. I found myself winding up the thread to breaking point because no water was coming out of the valve. When I took it off l found the rubber washer had block the hole cut from the self cutting valve. I unscrewed the middle part if the valve from the body and poked a long thin screwdriver through the rubber which cleared the hole.

Rated 1 out of 5 by from Failed after 1 day! Not impressed. The rubber seating washer failed within 24hrs causing a leak. Will not be using the same again.
