I’ve recently built a house on the shores of lac Gagnon QC in the Laurentians. I ordered your Retro-Line product to freeze protect the existing water line which runs 180 feet from the house down to a submersible pump about 15 feet deep the lake. The Retro Line arrived promptly. It took my plumber and I about an hour to install. The retro reel made feeding the line through the existing water line easy. Setting up the simple electrical receptacle it plugs into in my basement was also very easy. I have spent my first full winter absolutely delighted with your product… simply plugging it in mid-October and unplugging it near end of April. Thanks again!
