Great product
This is a great product and does what it says. I had a leak in my system which the plumber said was due to a faulty pressure relief valve he changed it and charged me £100. This did not fix the problem I put the Fernox leak sealer in myself and it cured the problem within a couple of hours I would highly recommend this productVerified purchase: YesCondition: New

Saved me a ton of money
So my boiler engineer was going to charge me over £100 to fix my pressure loss. Did a bit of ‘googling’ and found this product (much cheaper than screwfix might I add!). Got my husband to watch a YouTube video on how to DIY fernox express and bobs your uncle. So far, boiler pressure s between 1-1.5! I am a happy bunny. Thank you !Verified purchase: YesCondition: New
