The Grateseal stopped the drain smell and stopped the drain gurgle sound of other solutions.

Bought 2 of these after trying to get rid of the smell coming from the bathroom drains. There are no vent pipes, so the drains were the vent.

Thought that some drain cleaner would work, but our pipes were clean. A mate suggested these, so I gave them a try.

Once fitted up as per instructions, no more smell! In both bathrooms. We are very happy with this product. Thanks!

Easy installation and it does its work properly.

Simple concept and simple to install.
Installed two of these at home over the weekend. Unfortunately neither of the drains I was installing into were standard. One had been reduced by whoever installed it with mortar, so I had to get creative with the seal. The other drain had a 35mm pipe (weird) and I had a 50mm Seal unit. Again I got creative and used a coke plastic bottle lid, cut off to screw the oversized seal into place and create a fairly air tight seal, whilst still allowing the diaphragm to open and close.

Fixed the sewer odour immediately, great product.

Great product

Resolved bathroom smells and fitted both the shower and floor drain perfectly.

So easy to install, and I'm not handy at all! Took less than 5 mins.
Completely effective, bad smells are massively reduced and no more drain flies!
Shower is draining perfectly, no issues since installing.
Brilliant invention!

I can’t believe how far across the globe i had to look find something so essential

Packed, and delivered fast. Very happy with this, fits perfectly. Stopped our trap smell issue. Would highly recommend. Thanks👍🏻

Easy to install, anyone can do it.

Amazing product. Easy to install and works perfectly.

Works great. fast shipping.

The Grate Seal 100mm-80mm is a wonderful product. They have solved problems for me prior to this, and success is on the horizon with the latest pair when I get a chance in the next day or so.

It really works well, there are no more smells.
