Review: Brilliant for non pressurised weeping joint leaks. - I used this on an old upvc joint where the washing machine outlet plumbed into the sink waste. After connection of a new washing machine I had a very tiny leak. I had tightened as far as I could but the leak remained. This product cured the issue without the need to replace any pipes or joints. Great stuff.
Review: Sealant - Did the job. Would recommend
