Are You Refilling Your Spa More Often Than Usual?

Hot tubs and spas are a perfect place to unwind and relax after a long day. However, if you find yourself constantly refilling your spa, there may be an underlying issue. In this blog post, we’ll explore some reasons why your spa may be running dry faster than usual and provide some solutions to help you keep your spa water levels under control.

Firstly, one of the most common reasons for a spa running dry is evaporation. As your spa water heats up, it evaporates, leading to a decrease in water levels. However, if you’re refilling your spa more often than you think you should be, there may be other factors at play.


Leaking spa equipment or plumbing can cause a significant loss of water. This can occur when fittings, valves, or pipes are damaged, cracked, or loose. Water loss from leaks can be gradual, making it hard to detect. Keep an eye out for any water accumulation around your spa, as this could indicate a leak. Also, check the surrounding area for any wet spots or water damage.

Improper Water Chemistry

  • pH: If your spa’s pH level is too high, it can cause rapid water evaporation. High pH levels can also damage your spa’s plumbing, pumps, and other equipment, leading to leaks and other problems.
  • Hardness: High levels of calcium in your spa’s water can cause scaling and buildup on surfaces, including plumbing and equipment. This can lead to water loss and leaks.
  • Sanitizer: If your spa’s sanitizer levels are too high, it can cause rapid water evaporation. Sanitizers can also damage your spa’s plumbing, pumps, and other equipment, leading to leaks and other problems.

Environmental Factors

Environmental factors can also affect your spa’s water levels. If your spa is located in an area with low humidity, high wind, or high temperatures, water evaporation can occur at a faster rate. To combat this, consider using a spa cover to reduce evaporation and water loss.

Now that you know some reasons why your spa may be running dry faster than usual, it’s important to address these issues as soon as possible to prevent damage to your spa’s equipment and plumbing. Regular maintenance and upkeep can help keep your spa running smoothly and ensure that you can enjoy your relaxing soak for years to come.

The Top Culprit Behind Spa Water Loss

Are you constantly refilling your spa and wondering why the water level keeps dropping? The truth is, there are several reasons why your spa could be losing water. However, one of the top culprits is evaporation.

Evaporation is a natural process where water changes from a liquid to a gas state, and it occurs at all temperatures, even when the spa is not in use. Depending on the humidity level, wind, and temperature, evaporation can cause significant water loss in your spa, which means you’ll have to refill it more often than usual.

Other Possible Reasons for Spa Water Loss

  • Leaks: Cracks, damaged seals, and plumbing issues can cause leaks in your spa and lead to water loss.
  • Splash out: If you have an active spa, splashing and overflowing can cause water loss.
  • Backwash: If your spa is connected to a pool, backwashing the pool can cause water to flow out of the spa.

How to Minimize Water Loss Due to Evaporation

While you cannot stop evaporation entirely, there are several ways to reduce water loss due to this natural process:

  • Cover your spa: Covering your spa when not in use is the most effective way to reduce evaporation and water loss.
  • Check for leaks: Regularly inspect your spa for leaks and fix them promptly to prevent further water loss.
  • Reduce the temperature: Lowering the temperature of your spa can reduce evaporation.

Now that you know one of the top culprits behind spa water loss, it’s time to take action and prevent unnecessary water loss. By following the tips above, you can ensure that your spa stays full and functional for a longer time.

How Your Spa Cover Could Be Contributing to Water Loss

Are you constantly having to refill your spa more often than usual? The culprit behind your water loss may be your spa cover. While a good spa cover can help to retain heat and reduce energy costs, it can also contribute to water loss if it is not properly maintained or fitted.

If your spa cover is not fitted properly, it can allow water to evaporate at a much faster rate, leading to more frequent refills. Additionally, if the cover is damaged or cracked, it can also contribute to water loss as water seeps through the cracks.

Proper Maintenance

To prevent water loss caused by your spa cover, it is important to properly maintain it. This includes cleaning it regularly to prevent dirt and debris from accumulating, which can lead to cracks and damage over time. It is also important to ensure that the cover is properly sealed and fitted to prevent any gaps that could allow water to evaporate.

Consider a Cover Lift

Another way to prevent water loss caused by your spa cover is to invest in a cover lift. This will not only make it easier to remove and replace your cover, but it will also help to prevent damage that can occur from dragging the cover on the ground. Additionally, a cover lift can help to ensure that your cover is properly fitted and sealed, reducing the likelihood of water loss.

Replace Your Cover

If your spa cover is damaged or cracked, it may be time to replace it. A new cover can help to ensure that your spa is properly insulated, reducing energy costs and preventing water loss. When selecting a new cover, be sure to choose one that is the proper size and shape for your spa, and that is made from durable, high-quality materials to ensure longevity.

Simple Tricks to Prevent Water Evaporation in Your Spa

If you own a spa, you know that water evaporation can be a major issue. Not only does it lead to the need for constant refills, but it can also cause water quality problems and increase your energy bills. Fortunately, there are several simple tricks you can use to prevent water evaporation and keep your spa in top condition.

The first trick is to keep your spa covered when it’s not in use. A high-quality cover can reduce water evaporation by up to 90%, so it’s a must-have accessory for any spa owner. Additionally, using a floating cover or spa blanket can also help reduce evaporation and prevent heat loss.

Other Tricks to Prevent Water Evaporation
