Rated 5 out of 5 by Fernox Leak Sealer This product performs excellently for jointing BSP fittings as well as sealing 'old' weaping joints. A must have for all tool boxes! It is silicone based but the fittings are watertight immediately so you do not need to allow time for the paste to cure. NOT FOR USE ON GAS FITTINGS. 12 Oct 2011
Rated 5 out of 5 by sealed the deal! Had an "expert" fit me a new toilet, every pipe joint was left over tightened and leaking, I used this product before on a small leak and had enough to stop all the leaks around the new toilet! fantastic product, would always recommend its use! 21 Sep 2016
Rated 5 out of 5 by Sealed my leaky bits! Used this to stop some leaks on a few compression fittings. Sold the problem instantly 14 Sep 2016
Rated 2 out of 5 by Doesn't work Its states that it seals externally on a fitting. Have a few leaks on copper pipes. And the leaks are only weeping ever so slighty not dripping constantly, probaly one driy every 10mins, smeard this stuff all over. With the pipework relieved of pressure also. Left it a full 24 hours and then checked it with pressure back in the pipes to find the small leaks still the same so absoluty useless for this use! So if your thinking of using it for this use as it says it works for then save ur money and try something else. 14 Sep 2016

The soil pipe was new 2 years ago. Where this meets the ground I notice there is a small leak of water on floor. Is this product good to close this small leaking?

Answer: 
Hello Convey766. The LS-X will be able to stop small leaks, as long as it is applied to a dry surface and give sufficient time (about an hour) to set. Hope this helps.

Bath waste

How will this work on a bath waste as ours leaks when draining? Racking my brains as I feel could be an issue with the threading due to a few attempts with a few bottle traps?

Answer: 
Hello Stick71. LS-X will be fine to use on the bath waste, however you need to make sure the surface is clean and dry. Apply a thin layer and wait for an hour before using the bath again. Hope this helps.

Hi Stuart, Yes you can and it can go in both places, ensure that the joint and screw thread are dry and then cover with a thin coat of LS-X

My shower trap is leaking between the rubber under seal to the bottom of the tray. If I loosen the trap and put some of this in where the rubber seal is, is this stuff suitable?

Does this act like an adhesive and make it difficult to remove in the future or can it be removed easily?

Answer: 
Yes LS-X is suitable for this use, it will act like an adhesive but can be peeled/scraped off if you need to remove it.
