Can You Use Well Water For A Hot Tub?


Yes, you can use well water for filling a hot tub up. However, you may need to install a water softener if your well water is hard.

Additionally, you’ll need to make sure that your hot tub’s plumbing can handle the higher mineral content of well water.

Otherwise, using well water for filling your hot tub should be no problem.

Can A Hot Tub Be Filled With Well Water?

Yes, a hot tub can be filled with well water.

However, it is important to test the water first to make sure that it is safe for use.

Well, water can often contain bacteria or other contaminants that can cause illness.

A hot tub filter will not remove all of these contaminants, so it is important to have the water tested before using it in a hot tub.

If you do decide to fill your hot tub or spa with well water, there are a few things that you need to keep in mind.

First, you will need to pre-treat the water before adding it to the hot tub.

This can be done by adding chlorine or another disinfectant to the water.

Second, you will need to run the pump for longer periods of time to circulate the water and help remove any contaminants.

Finally, you may need to install a water softener or well pump if your well water is hard.

How Do You Treat A Hot Tub With Well Water?

If your hot tub is connected to well water, you will need to add a sanitizing oxidizer such as chlorine or bromine to the water on a weekly basis in order to keep the hot tub water clean and free of bacteria.

You can purchase chlorine or bromine tablets from most pool supply stores, and you should follow the manufacturer’s instructions for dosage.

You will also need to add a pH balancer such as soda ash or baking soda on a monthly basis in order to keep the balance of the pH level of the water within the correct range.

The correct pH range for hot tubs is between 7.2 and 7.8.

Too low or too high of a pH can cause skin irritation and other health problems.

Can You Use Hard Water In A Hot Tub?

Yes, you can use hard water in a hot tub.

However, it is important to understand that using hard water in a hot tub can potentially lead to mineral build-up inside the hot tub equipment itself.

Over time, this calcium mineral build-up can lead to the deterioration of the hot tub’s internal components, shortening its overall lifespan.

Additionally, the mineral build-up can also cause the hot tub’s heating elements to become less efficient, meaning that it will take longer for the water to fill a hot tub to reach the desired temperature.

For these reasons, many people who have hard water opt to install a water softener in their homes.

A water softener works by removing minerals from the water before it enters the hot tub.
