MachIII 0 Report post Posted July 27, 2010 Hi all, I would like to know the market price to install a storage heater in my unit since it is more than 10 years old. The water feed into the toilet is at the moment, a single pipe in. I understand there is a requirement of two piping for both cold and hot water from storage tank unit. May i know how much will it cost to install additional piping and mixer in my toilet? Any similar experiences to share? Thank you. Regards. Share this post Link to post Share on other sites
