Pressure keeps dropping on Vaillant boiler and water is coming out of overflow pipe.

Hi, the pressure relieve valve has to be changed but the main problem might be the expansion vessel. When you will change the PRV check also the expansion vessel pressure. If there is no pressure in the expansion vessel, you can repressurise it or it is faulty and you will need to change it also. Regards. Sevket My gas builder

Hi Ann I would recommend to post a job on main website because some of a job needs to be seen before any advice is given. Our service is free of charge with no obligation quote and our tradesmans are happy to help with every aspects of jobs. If you post a job on Rated People home page then 3 companies will get in touch then you would be able to choose the right person as you would receive an e mail with a link to tradesman account where you would see a pictures and you will read previous from previous customers. I hope this will help Best regards Rafal
