As Old Man Winter approaches, many communities begin to worry about freezing temperatures and the damage they may cause to their aeration or fountains in winter. As a result, we field several calls a day this time of year regarding how to best protect equipment. This is a valid concern as extended periods of sub-freezing temperatures can cause unnecessary strain on motors, shafts, and impellers.
Northern latitudes are subject to extended periods of ice covered ponds. However, here in north Texas, pond surfaces rarely stay frozen for more than 24 hours at a time. Therefore, we typically do not recommend removing the fountain from the pond and storing it over the winter. The best approach is to keep an eye on the weather forecast and make sure your pond is prepared in the event of a prolonged deep freeze.
For North Texas fountains in winter, it’s on or off
We typically recommend one of two things under these conditions. First, the fountain can be completely turned off until the pond thaws. Cold water holds higher levels of dissolved oxygen; therefore, the biological importance of supplemental aeration is greatly diminished over the winter. Secondly, the timers can be adjusted to run 24/7. This will prevent the fountain from turning on while being encased in ice; potentially harming critical components of the unit. The agitation created by the fountain will often prevent the pond surface from completely icing over.
Also keep in mind that winter rains can increase the likelihood of fountains getting clogged with trash or other debris. If not corrected, these clogs can cause overheated motors and possibly shortened motor life. Therefore it is critical to be attentive of any changes to the spray pattern. Things to look for include a significant diminish in output or a less defined display pattern. With a temporary change in operating times, a watchful eye on the spray pattern, and a little maintenance as needed, your fountain should be ready for the oncoming spring.
