VR6Crazy 0 Posted November 1, 2010 Report Share Posted November 1, 2010 Hi GuysMy water expansion tank keeps overheating. When I got to work this morning the water was bubbling through the little hole in the tank. I have to fill my water tank every day at the moment - there was a leak but I put some of that RadWeld into it yesterday and it looks like the leak isn't dripping anymore. Just wondering if anyone has had this problem before.Thanks guys!!xx Link to post Share on other sites

craggsy 91 Posted November 1, 2010 Report Share Posted November 1, 2010 Could just need the cap changing. What colour cap you got? Link to post Share on other sites
spadam 7 Posted November 1, 2010 Report Share Posted November 1, 2010 Or the seal around the tank cap is £6 from tps and bottle is £20 from tps also. Not sure if you can buy just the seal seperatly. Link to post Share on other sites
