Rated 3 out of 5Â by Rambler A round peg for a round hole
I read the review about using these to change the gate valves leading from a water tank and wanted to do the same.
However, when I got to the job I found that the outlet hole from the tank had two ridges, either side, probably as a key for a spanner or other tool to hold the tank coupling for tightening the external nut.
So the exit hole from the water tank wasn't round and wouldn't take a round bung.
A nice idea if it had worked. The drain plugs themselves seem to be fine. I'll keep them for another emergency.

These plugs worked a treat when I needed to replace the three gate valves coming from my loft tank. Thankfully, (possibly by design) the fitter had used two 22mm and one 28mm pipe so the set had enough to cover the job.
It doesn't take much to close the flow and you need to resist the temptation to over-tighten them. It doesn't take much to get a seal and the nylon wing-nut will skip the threads if you over do it. Once you feel resistance then a quarter to half a turn is all it needs. You will get the feel for it.
Only downside is the cost and the need to buy it in a fixed set. I'd rather they did these in singles to allow you to pick what you need. As mentioned, if the three outlets had all been the same size then I would have been stuffed for another Â£18. Of course, if that was the case then I would have bought from manufacturer and paid the postage.

Rated 4 out of 5Â by DIYRobP Quite expensive, but handy
Seem well made and certainly up to the job (blocking pipes in a hot tub whilst changing pumps etc). A little pricey for what they are, but do exactly what they are meant to do.

These little things are great, there marked up for dry commissioning only but i mainly use mine to block cold feeds in large storage tanks! It saves on draining the whole tank and that troublesome air locked pipework after too!!
Mine have paid for themselves the 1st time i used em!
