Where to Drain the Water

To speak generally, you can drain hot tub water onto your garden or lawn. You can even hydrate plants with the water. If your hot tub water has the right pH levels and the right chemicals, rest assured that the water is not going to damage your plants. The water does not contain anything that is harmful to plants.

But if the pH level and the chemicals are imbalanced, make sure you proceed with caution. If the water is still hot, make sure it is cooled before you are using it in your garden. Leave the water for some time and it will cool down.

Depending on the size of your hot tub, it may contain a large amount of water. If your yard is covered in concrete, consider draining the water somewhere else. Use your common sense and determine where the water should go.

Using a pump

If you are willing to spend a little bit of money to buy a pump, you can get the job done pretty quickly. With the help of your hose, the machine will pump out water. These are the steps:

  • First, choose a hose and attach a pump to it.
  • Put one end of the garden hose inside the water. Make sure it goes a little deep. Otherwise, it may not be able to draw out water. In that case, it may not get the job done.
  • Where would you like to drain the water? Put the other end there. If the water does not contain any fresh chemicals, the water can be used in your garden.

Using the force of gravity

Many professionals out there use the first method. However, you might prefer the second method that we are going to discuss. This method involves using the force of gravity to drain the tub. If you are not doing it regularly, the second method is a better way to get the job done.

If you are wondering how to drain a hot tub with a garden hose, here is an easy method for you. Apart from the hose, you are not going to need other tools. However, remember that while the process is simple, it is a bit time-consuming. Here are the steps:


  • Attach one end of your garden hose to a faucet. Keep the other end in the hot tub.
  • Now allow the water to run through your garden hose. Once you have finished this step, make sure that all the water has come out.
  • Remove the hose from the faucet and turn it off. Find a place where you want to put the drained water. Make sure the place is at a lower level. It can be placed in your lawn or garden. You can use the water on your plants.

This is how to drain a hot tub with a garden hose. Just sit and relax while the water is going out.

Clean And Inspect Your Hot Tub Regularly

When it comes to cleaning hot tubs, most hot tub owners tend to procrastinate. In some cases, it is okay. But keeping your hot tub clean is of utmost importance. Make sure you have a schedule for cleaning your hot tub regularly. It should be an essential part of hot tub maintenance.

As a rule of thumb, you should clean your hot tub once in a couple of months. But if your hot tub is used commercially, it should be cleaned multiple times in a week. To remain healthy, make sure you maintain the necessary hygiene.

Your hot tub also requires regular inspection. Inspect the tub and see if it is having wear and tear. The spa may work improperly if there are malfunctions. To keep a hot tub functional, maintenance is vital. When there is no water in your hot tub, you can easily fix broken parts.

Hot tubs are usually designed in such a way that the sides repel stain and dirt. So, you can easily get the job done with a wet washcloth.

Refilling your Hot Tub

The procedure of refilling a hot tub is not hard or complicated. To complete the task, a garden hose is the only tool you are going to need. Just find a water outlet and hook up the hose to the outlet.

However, you will have to deal with air bubbles if you are trying to get the job done without a fill valve. In most cases, air bubbles do not cause any problem. But sometimes they can impede the proper functionality of your hot tub.
