Will Epsom Salt Damage Jacuzzi Tub Jets

In short, no. Epsom salt is often used in Jacuzzis and hot tubs to increase the magnesium levels in the water, which can be beneficial for the skin. However, its important to remember that too much Epsom salt can actually be damaging to the Jacuzzi jets.

Its important to follow the directions on the package and only use the recommended amount.

Epsom Salt Increases The Total Dissolved Solids

Epsom salt is commonly used in regular bathtubs. When being used in the bathtub, the standard recommendation is adding about 2 cups of Epsom salt to enjoy the full therapeutic effects.

On average, bathtubs hold approximately 80 gallons of water. Standard hot tubs, on the other hand, hold between 400 and 500 gallons of water. To reach the same concentration in the hot tub, you will need to add 10 to 12 cups of Epsom salt this is a lot of solids.

Bathtubs are extremely easy to drain and are usually drained regularly. Unfortunately, hot tubs are usually not drained as easily or as often as the bathtubs.

To prevent scale buildup in the hot tub surfaces and equipment, hot tub manufacturers recommend draining a hot tub when the level of the Total Dissolved Solids reaches 1,500 ppm. Failing to do so can easily void your warranty.

Using Epsom salt in a hot tub by adding 10 to 12 cups can quickly raise the Total Dissolved Solids, reaching far past the recommended maximum threshold of 1,500 ppm. Although the hot tub heaters usually sustain the most damage from the scale buildup, jets, pool pumps, tub surfaces, and water lines can also accumulate scale if you fail to maintain an ideal water balance.
