Ooo new products, sounds like Santa's elves aren't the only ones being working away in there workshop. Can't wait to see what you've cooked up.

used mine and its brilliant, sadly alone so no photos but the coverage was brilliant

Fantastic! I'm so glad you are enjoying it, did it deliver the gunging you were hoping for?

It did was very good, as the video you did it covers, ive mine in a plastering bucket from screwfix so its 30litres and i used a set of steps as a platform, if it can hold my fat ass it can hold that

30litres! That's a big gunge capacity. Must have been quite a long gunging. So glad that it gave you the gunging you wanted and I hope it gives you many more.

Do you just seal around the edge? Or did you use some adhesive first

I used a silicone bathroom sealant all over the flat surface of the flange. Ince dried there's enough surface area to adhere it to the base.

Where's the best place to give feedback for potential future designs? Have come to the conclusion after much experimentation I wouldn't go with the current iteration for my current tank projects - though as I'm not in a particular rush with those given it is currently freezing out it might be a future design would work for some of the many valves I'm intending for the project.

Hi,
If you've got some ideas you'd like to see in future versions of the valve or if you e got something you'd like to custom commission then feel free to inbox me on here.

Do you have any sealant brand recommendations? I used unibond; it stuck to the valve but not the box I put it in :/

So ot sort of depends on what the box is made of. I used lsx on mine which is set into a bucket. I'd recommend scuffing up the surfaces to be stuck with some sandpaper before sticking them together. Some other people have told me they've used a contact adhesive like uhu but I've not tested that on the valve plastic yet so I can't fully recommend it. The other thing I would suggest is to make sure that you give whatever adhesive you choose ple ty of time to dry (24-48 hours)
Hope this helps.
