How To Winterize Your Cottage

Keep your cottage plumbing system safe through winters with WINTERPROOF™ All Purpose Water System Antifreeze and our BURST GUARD™ Guarantee -100˚F. Follow these simple steps to avoid complications and costly repairs:

1 Turn off power to the water pump and hot water tank.

Turn off the power in the hot water tank to protect the heating elements from trying to warm water that is no longer there.

2 Work on interior plumbing first.

Ideally, all the supply pipes will drain to one point, and the water supply lines will gradually slope down to a single set of drain valves. If your cottage is set up differently, you may have to crawl under the cottage to find out where all the pipes go and where the valves are located.

3 Open drain valves and make sure all taps (inside & outside) are open.

Leave all valves and the taps open over the winter so that any remaining water can drain out.

4 Attach an air compressor to the drain valve.

If you think there may still be water in the line from improper drainage or sagging pipes, blow any excess water back through the open taps.

5 Drain the pressure/gravity tank and hot water tank.

If the pressure tank is located somewhere other than below your cottage, make sure the line to the cottage is also drained. The pressure tank relies on a rubber diaphragm to create and hold the pressure to push water through the plumbing lines. If water is left inside the holding tank, it will freeze and possibly destroy this rubber diaphragm, making the tank useless.

6 If you have a jet pump, remove the drain plug.

Drain the water between the pump and the pressure or gravity tank. The priming plug should also be removed and stored in a safe place. Add 500 mL (2 cups) of WINTERPROOF™ Water System Antifreeze to the jet-pump case to protect the casing and impeller inside it from freezing. Disconnect the waterline to the pump and pull it onto the shore. Disconnect the foot valve and store it in a secure place to prevent any damage.

7 If you have a submersible pump, leave it in the water during the winter.

A drain valve installed on the waterline just above the lake’s high-water level will let you drain the line from the cottage to where the pipe enters the water, decreasing the chances of freezing and cracking over the winter.

8 Winterize the toilet.

Flush the toilet to get as much of the water out of the tank and bowl as possible. Some water will be left at the bottom that should be removed with a small cup or a sponge. Add 1 to 2 litres (4 to 8 cups) of WINTERPROOF™ Water System Antifreeze to the bowl to prevent any remaining water from freezing and cracking the toilet, and to stop sewer gas from venting back through the toilet trap. Add another litre (4 cups) of WINTERPROOF™ Water System Antifreeze to the tank and make sure the bottom rubber flapper in the tank is tied in the up position to prevent it from sitting in the plumbing antifreeze.

9 Winterize the sink & tub.

Pour 500 mL (2 cups) of WINTERPROOF™ Water System Antifreeze down every sink and tub drain. It is normal for the product to become ‘slushy’ and freeze in sub-zero temperatures, but it will not damage the system.

10 Winterize the shower.

Pour 1 litre (4 cups) WINTERPROOF™ Water System Antifreeze down the shower-stall drains. The traps under the drains hold water that prevents sewer gas from coming up through the drains. If left unprotected, the pooled water in the traps may freeze and crack the traps.
