Contacted Watertank Cleaning Company as I got a flyer in my mailbox and had no idea I should be cleaning my tanks. Paul was great and talked me through the process and booked in a time that suited me. He has just left now and I must say I can't believe I was using water out of this tank after seeing all the dirt that was removed from it. Paul was very professional, did a thorough job and only charged me half price for my second tank as part of a deal they were doing. I will definitely use the Watertank Cleaning Company next time around now I know how filthy my tanks get and how good a job they do.
