How To Summerize Your Spa

How to Drain Your Spa For Storage for the Summer:

Your spa was likely designed to drain well when you use the built-in drain. But several areas may not drain well so you need to give them attention.

First, remove the left over water inside the spa after draining. Open access panel. (spa power should be off)

Second, depending on your spa, you have 1-3 pumps to be concern about. On each pump loosen the front fitting where the pump mates with the spa plumbing. On some pumps you will see a knob drain valve below the front fitting. This is there to allow remaining water to drain. Loosen or remove.

On smaller circulation pumps you have to pull the hose off the front of the pump. Also good to remove as much water from the pipes as you can. A wet vacuum can be used to suck the remaining water out of the pump.

Third, the heater. Loosen one or both fittings to the heater to allow the water to drain. If you find no water dripping out when you loosen, shake the connection to break a possible seal to allow water to drain.

The above should drain and dry the most important parts of your spa during the summer months.


How do I stop my Spa from Over Heating during the summer?

If the spa is not malfunctioning, the major reason spas overheat is due to the sun. During the summer the spa may rarely if ever actually turn on the heater. But because the spa either filters or has a circulation pump, the water moving can add heat. That water movement plus the sun beating down on the spa during the summer can be a problem. It's not unusual for spas to overheat in the summer because the insulation holding the temperature in, water moving add temperature to the water, and the sun beating down adds temp each day. Because there is little temperature loss  the spa gradually increases. Then, OH. Most spas are designed to go to OH somewhere between 112-115 degrees.

Possible Solutions:

Right Arrow Change filter cycle times to times other than mid day filtering. I have found this works well. Filter early morning and later in the day often solves the problem.

Right Arrow Customers have sworn on just propping up the cover to let the heat escape. One simply put a piece of 2x4 to allow heat to solve the problem and never had a problem again.

Right Arrow If you have a 24/7 circulation pump and don't want to use the above method, you might have to turn power off to the unit. This would be the least desirable method because the spa is design to keep water moving and keep the water clean. Turning the spa off will leave a stagnant body of water sitting and that will encourage growth in the water.

Right Arrow Fortunately the newer models have a "summer logic" that will automatically account for this problem and turn off the spa's circ pump if the water gets above 2 degrees set point. What this means is if you set the water temp to 96 degrees. When the spa actual temp reaches 99, the circ pump will turn off. Note that the reason it would reach 99 is not because the heater was on but solar and stored heat over time is building up. The "summer logic" is designed to minimize spas getting too hot during the summer's heat. In winter this logic circuit is not likely to come on because of the cold weather. Once the "summer logic" activates, it will turn on periodically to "stir" the water in the spa to keep it clean.
