If you’ve noticed that your Pentair spa is running low on water, it’s important to figure out why. Not only can a low water level be frustrating, but it can also be damaging to your spa if left untreated. Keep reading to learn more about common causes of low water levels and what you can do to fix them.

Evaporation

  1. What is Evaporation? Evaporation is the natural process of water turning into vapor due to exposure to air and heat.

  2. How does it affect my Pentair spa? Water in your Pentair spa is constantly exposed to air and heat, which means that evaporation will occur over time. This can lead to a decrease in water level and a need to refill your spa.

  3. How much water can evaporate? The amount of water that can evaporate from your Pentair spa depends on a few factors, such as the size of your spa, the air temperature, and the humidity level. On average, you can expect to lose about 1-2 inches of water per week due to evaporation.

  4. How can I prevent excessive evaporation? You can reduce the amount of evaporation in your Pentair spa by using a spa cover when your spa is not in use. This will help retain the heat and reduce exposure to air, ultimately reducing the amount of water that evaporates from your spa.

If you notice that your Pentair spa is running low on water, evaporation is likely one of the reasons. Understanding the factors that contribute to evaporation can help you take steps to prevent excessive water loss and keep your spa in optimal condition.

Leaks in the Spa

If you’ve checked for evaporation and the water level is still low, there may be a leak in your Pentair spa. Leaks can cause your spa to lose water and can also lead to other problems such as water damage to your property. Here are some common causes of leaks in a Pentair spa:

  • Broken or damaged pipes: Over time, the pipes in your spa may wear out or become damaged, causing leaks. This is a common problem in older spas.
  • Cracked shell: If your spa shell has a crack, it can lead to leaks. This can happen due to wear and tear or extreme temperature changes.
  • Worn out seals and gaskets: The seals and gaskets in your spa can become worn out over time and may need to be replaced to prevent leaks.
  • Pump or heater leaks: Your spa’s pump or heater can develop leaks, causing water to drip out of the spa.
  • Jets: The jets in your spa may become loose or damaged, causing water to leak out of the spa.
  • Filter leaks: If your spa filter is damaged or worn out, it can lead to leaks.

If you suspect that your Pentair spa has a leak, it’s important to get it repaired as soon as possible to prevent further damage. A professional spa technician can help you identify the source of the leak and make the necessary repairs.

Water Splashing Out of the Spa

Water jets: If your spa’s jets are positioned too high, the force of the water can cause it to splash out of the spa. Ensure that the jets are directed downwards and not towards the edges of the spa. You can also adjust the power of the jets to minimize the splashing.

Bather load: Having too many people in the spa can cause the water level to rise, resulting in water splashing out. Be sure to follow the manufacturer’s recommendations for the maximum number of people allowed in the spa.

Windy weather: Windy conditions can cause water to splash out of the spa, especially if the spa cover is not securely fastened. Consider installing a windbreak to reduce the impact of the wind on your spa.

Spa cover: A damaged or ill-fitting spa cover can also contribute to water splashing out. Ensure that your spa cover is in good condition and fits snugly over the spa to prevent water from escaping. You can also consider purchasing a cover with a wind strap or locks to further secure it.

Common Causes of Low Pentair Spa Water

Evaporation: One of the most common causes of low water levels in a Pentair spa is evaporation. Water can evaporate quickly in hot temperatures, especially if the spa is not covered when not in use.

Leaks: A leak in the spa can also cause low water levels. Check for visible cracks or damage to the spa shell, pipes, or fittings. A professional should be contacted to repair any leaks.

Draining: Draining the spa for maintenance or cleaning is necessary, but forgetting to refill the water can cause low water levels. Be sure to fill the spa back up to the proper level after draining.

Splashing: Water can splash out of the spa if too many people are in the spa at once, or if there is excessive movement. Be sure to not exceed the spa’s maximum capacity and to limit movement to prevent water from splashing out.

Improper chemical balance: If the spa’s chemical balance is off, it can cause the water level to drop. Check the chemical levels and adjust them accordingly.

Dirty Spa Filters

One common cause of low water levels in a Pentair spa is dirty spa filters. Over time, the filters can become clogged with debris, making it difficult for water to flow freely through them.

If the water in your spa is low and you suspect that dirty filters are the culprit, it’s important to clean or replace them. Cleaning your filters regularly will prevent the accumulation of debris and ensure that your spa is functioning at its best.

  • Check your filters every two weeks and clean them as needed.
  • Replace your filters every three to four months.
  • Consider using a filter cleaner to remove built-up dirt and debris.
  • Regular filter maintenance will improve the overall water quality of your spa.

By keeping your filters clean and well-maintained, you can prevent low water levels and ensure that your Pentair spa is running smoothly.

Pump Problems

Another common cause of low water levels in your Pentair spa is issues with the pump. If your pump is not functioning correctly, it may not be circulating the water as it should, which can cause the water level to drop.

One possible pump problem is a clogged impeller. If debris builds up on the impeller, it can prevent the water from circulating properly. This can cause the water level to drop, as well as lead to other issues with the pump and spa.

Another issue with the pump can be a malfunctioning check valve. The check valve is designed to prevent water from flowing back into the spa when the pump is turned off. If the check valve is not working correctly, water may leak back out of the spa, causing the water level to drop.

If you suspect that your pump is the cause of your low water levels, it’s essential to call a professional to assess and repair the issue. Attempting to fix the problem yourself can lead to further damage and potentially costly repairs.

Regular maintenance and cleaning of your spa pump can also help prevent issues from arising. Be sure to clean the pump and impeller regularly and replace any worn or damaged parts as needed.
