I used this bung on my roof rain water down pipe.
I used this bung on my roof rain water down pipe. The standard waterbutt down pipe conversion kit kept getting blocked by slugs, wasting rain water, I have removed it and replaced it with a pipe that now goes directly into the waterbutt as shown in the attached photo.3 water buts are connect to the main water butt, the 3rd containers a waterbutt pump which is connected to a hose pipe for watering my garden.

100% seal
Used for building control inspection. 100% seal on new pipework. Smooth thread so easy to tighten and untighten with onehanded, which is ideal if you are testing 360 inspection chamber which are arms length deep.
