Hot water system burst on friday night. after isolated the water and power i called the plumbing Doctors. They arrived early Sunday morning Free Quoted the job & arrived 7.30am Monday to install a new system. The house appeared to have been built around the old hot water system and couldnt be removed, so the new system had to be relocated, replumbed & rewired. after sales service was also excellent. All good, Personally i rate the repair at 5 star
