Ronald from Jamaica asks

I have an underground PVC pipe leaking, will Miracle Seal liquid work?

Electrical World Replies:

Hello, Miracle Seal will work in a sealed system, such as a heating or cooling system, as it has to stay in the pipework for it to take effect. It will not work on waste pipes etc as the liquid would run straight through. I hope this helps.

I have a plastic roof in my pergola Small drip right in the middle Needs to be fixed from underneath Impossible to get on top of roof unless I dismantle everything will this help

Electrical World Replies:

Hello, this product is a liquid designed to be poured into cooling systems to seal leaks, so it will not be suitable for your requirements, sorry

Billy from Ireland asks

Hi, will this seal gaps in roof tiles?

Electrical World Replies:

Hello, thanks for the question. No, this product is not suitable as it is a liquid designed for repairing cooling systems. How large are the gaps that you are wanting to seal?
