Hi All, My mum's Worcester Bosch 4000 has a pressure leak. Pressure was fine for 14mths then was dropping from 1.3 bar to 1 bar every 9-12 weeks. Can't find any leaks anywhere on visible pipe work or radiators. What are the views on using a leak sealer to try to resolve this? Thanks

Hi All, My elderly parents are having some work done this week for a barrier damp course. The builders said there's no lintel above the external back door. House is 90 years old current door been in about 20 years. Any advice please worried sick about them
