Fernox LS-X External Leak Sealer, 50ml, White, Plastic & Metal, Handheld, Sealer

Used this magical stuff to sort both a leaking pipe to a basin tap and a dripping toilet waste pipe. Have recommended to friends who have also had success with leaks.The fact that it never dries and is easy to remove makes it worth a punt to cheaply fix a leak instead of calling out an expensive plumber.It can be tricky to get off your hands after.

Really good stuff for preventing nip leaks or for those of us who like a belt and braces approach to plumbing. It won’t take much around a seal to make it water tight. The only reason for not giving it 5 stars is that it can look a bit messy and you can’t paint over it - so be neat with applying and wear gloves!

This product is amazing. Makes pipe joints leakproof,and if you have any weeping joints, coating the area around joint seals like magic.

My toilet cistern was leaking from the overflow pipe & underneath. A plumber waa not able to come out for over a week. I bought this as a temporary measure. It worked! Make sure the area you are applying it to is dry.

Very messy - needs an applicator. Did not work for this particular leak but I have used before and it did the job
