I had my solar HWS installed by mainline plumbing as a service provider for Sola Edwards Adelaide in April 2012. At that time they were polite,prompt,tidy and efficient in attending to the installation. Yesterday I contacted them regarding problems with my HWS poor flow rate problems. I was given polite,accurate and helpful information over the phone to enable me to locate and clean the filters which were blocked. This saved me a plumbing fee for a simple task and the honesty was much appreciated as I may have been taken advantage of for a plumbing call out by someone disreputable.
