Incorrect Items:

14 days from receipt of order, strictly only for products in unused, original condition, with labels & packaging (card and clip) intact.  Please contact us at sales@grateseal.com.au to arrange the return process.

Return postage is at purchaser’s expense.

For health and safety reasons, we are unable to accept products which have been placed (either fully or partially) into drainage outlets, even if size is determined to be incorrect.

Products which have been customised/trimmed cannot be returned. It is therefore crucial to obtain accurate measurements of floor or shower waste outlet pipes (where the Grate Seal will be installed) to ensure the correct size is purchased.

To avoid damage and to extend the life of the Grate Seal product, no harsh or abrasive chemicals (e.g. bleach, Drano, etc) should be used while the Grate Seal is in situ.  Please remove the Grate Seal product prior to their use.

Damaged Items:

Should you received your item in damaged/faulty condition, please contact us at sales@grateseal.com.au

Description

Create a permanent and maintenance free, one-way seal that is easily adaptable to fit either 4"/100mm or 3"/80mm floor and shower drains with the GS01 Grate Seal®.

The GS01 Grate Seal® is a specially designed rubber, one-way valve that is easily retro-fitted into 4" or 100mm and 3" or 80mm floor and shower drains preventing sewer gases, airborne bacteria, soap suds, vermin and noise from making their way out of the drainage system into habitable areas.

As a WaterMark® approved product, the one way valve does not restrict flow, and the flow rates achieved more than cope with the maximum allowable flows from plumbing fixtures such as showers. Unlike other products on the market, a water seal is not required for Grate Seal® to be 100% effective making Grate Seal a permanent and maintenance free solution.

Grate Seal® is produced from an antimicrobial polymer compound making it durable and resistant to breaking down and allowing it to be used in a wide variety of applications, including the medical and commercial field. 

Grate Seal® is supplied at a low cost considering the problems that are resolved without having to remove or replace tiled surfaces, concrete, waterproofing, etc. 

  • Unit is one piece and self cleansing. 
  • No ridges or braces to obstruct or catch waste. 
  • No fixing required as the seal stays in place through friction. 

Simply cut along the marked line to convert from 4" or 100mm to 3" or 80mm (GS01 model only). You can also watch a tutorial on our Youtube channel here.

Easily trimmed to size and easy to fit.

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.

Great Product

My drains are 90mm at top so used the off cut to place around the 80mm and works fine.
Suggest you could advertise the fact.

Happy with the result for my 3 drains.

The perfect FIX to an odour problem!

I was not sure how I was going to fix the odour problem from a ground floor shower drain, an odour that then permeates the whole downstairs apartment reno. It would have been a huge amount of work / expense to cut up 65 year old concrete floors to work out where pipes are running and what sort of trap could be installed. It took 10 minutes, once I stopped avoiding trying to find a simple solution, to find this product. It's perfect! It will actually slip over the lip on the new shower drain frame. I'll set the frame into the floor with a decent silicon, so if it ever needs replacing it will be a very simple case of slicing out some silicon and putting in a new one. Extremely happy I found this product.
