Both pumps were originally put into service around 1980.
North pump # 2 was replaced in the fall of 2004. At the time it was replaced, care was taken to install a heater line to prevent freezing as well as foil-backed insulation. As well, spacers were used to keep the pump and intake line in the middle of the 6" plastic pipe it was installed in and a baffle was used to prevent water being drawn from above the pump but rather to ensure water is drawn from the bottom so it flows over the pump keeping it cool.
The pump installed in 2004 was a Webtrol WT1830 220V 3 hp. It was obtained from what was then Interior Hardware in Nelson.
In February 2014, some sustained cold weather froze (as usual) the south intake line (pump # 1). This time the freezing ruptured the 2" galvanized intake line. The decision was made to replace the pump and control box as well as the intake line, installing insulation and heater wire along with the pump. The new pump was installed in March of 2014 along with a new control box, new intake pipe, insulation and freezing protection. The pump was purchased from Western Pump in Calgary.
In March 2021, north pump # 2 failed, presumably because of an internal short. On March 5th, the pipe and pump were removed and a new pump ordered. This pump was ordered from Western Pump in Calgary (sales@westernpump.ca).
If a pump fails or needs to be removed and/or replaced, the following guidelines might be of some help.
Turn off and disconnect the pump being worked on. Set things up in the treatment building so that pump can't be used by either the manual switches or the timer.
There is an opening in the west wall of the lake building that allows for access by a chain and cable from a cable pull. Sections of pipe can be pulled out through this as they are removed.
Clamp a cable and/or rope to the 2-inch pipe from the lake and then disconnect the union holding that pipe to the rest of the plumbing. Carefully begin to pull the pipe along with the pump out of the lake. Disconnect sections of pipe as necessary, making sure at all times to have some kind of secure way to hold on to the pipe and pump still remaining. There is a rope attached to the pump motor as well as the electrical wires. Both need to be pulled out with the pipe and can help to secure the pump when changing pulling locations.
When reinstalling the pump, it would be good practice to replace the pipe, at least the sections that have been below water because there will be some corrosion and the strength of the pipe will be somewhat reduced. You will have removed insulation around that pipe along with a heat trace and electrical supply line. Note how all that was installed and replace things the same way. If necessary, take pictures as the pump is removed.
