Do You Need A Blower In A Hot Tub?

A hot tub blower is a device for keeping the air circulating and breaking down the scent of sweat and mildew in a hot tub.

You will typically find it at the end of a hose leading away from your hot tub, most likely underneath your deck or outside.

Usually positioned on an adjustable pole, you should turn on these blowers before getting into the water to avoid excessive heat and smell while you soak.

Once in, it would be best if you turned the blower completely down, so it only circulates the air in your hot tub.

Yes. The blower will keep your jets working to supply you with a nice, powerful massage. It will also maintain your water temperature while making it easier to filter out dirt or particles. A suitable blower will also prevent the jets from getting clogged, which can be very unsanitary.

This can help retain the cleanliness of your water and make sure any new dirt doesn’t get into it.

A blower is essential in a hot tub because the hot air helps heat up and maintain your water temperature while also making it easier to filter out dirt or particles.

Blowers come in different sizes and styles. The most crucial factor to remember when looking at blowers is what size hot tub you will be using.

Every hot tub operates differently, and some may require a blower explicitly sized for that particular model.

Once you have a general idea of the tube size, you can narrow down your choices.

There are very few blowers that are unbreakable. You should consider fiberglass and other plastic parts because they break down over time.

Blowers that use electrical power may handle this pressure, but you may experience some problems such as blowing just a tiny bit of air or making it impossible to shut off the water flow at the bottom or top of your tub.

There is always a trade-off with any blower, so keep this in mind when buying one.

When choosing a blower, it’s essential to ensure you get a product that will fit your hot tub.

I recommend that you get an extra-large blower that will extend to the bottom and top of the hot tub.

This will help prevent your tubes from getting blocked with dirt and maintain clean jets and water.

Will A Hot Tub Heat Up Without The Jets On?

No. That’s not how it works. If you want the jets to heat the water, you have to turn them on before adding your body into the tub. Ideally, you should already be in the tub before switching them on.

It might take two hours for your hot tub to heat up enough to enjoy with jets off, but this is only true if you turn on both your water heater and the filter.

Without them also working, your time could easily quadruple or worse. Just think about how much power you would have to use without a filter.

The amount of time it takes for a hot tub to heat up depends on the size of your tub and what kind of filter you’re using. The larger the tub, the more time it’ll need to heat up.

It will get HOT faster than usual with no water circulating from the heater.

Generally speaking, the average hot tub takes about an hour to heat up without the jets. That’s without any filter, which, as you know, increases the time greatly.

Some of these models have timers that can be set for every 20 minutes so that anyone using the tub will not get shocked.

When you add jets into your hot tub’s heating process, you increase the work needed to heat your water. Those pumps need to circulate more water than they usually should.

Do All Spas Have A Blower?

Yes. All Spas have a blower. Without this essential piece, the Spa would be useless for any therapy or relaxation.

The Spa’s blower circulates water and bubbles through the air to provide relief from stress and muscle tightness.

It also pumps in heat and helps with cleansing by extracting toxins from deep within your pores.

This device is your Spa’s engine because it produces the Spa’s soothing sound that you’ll find so relaxing.

Its recommended that you maintain the volume at an acceptable level to maximize your Spa experience.

Of course, many other factors affect noise output as well. The number of jets and their locations will play a large role in how much noise the blower produces while it’s running.

The more jetted tubs and Spas tend to be louder than those with fewer jet options.

The condition of your Spa’s blower will also affect the amount of noise it produces. If it needs regular maintenance, you may hear irregular splashing noises or excessive buzzing during use.

You can find several types of blowers inside Spas today, though not all are appropriate for use by customers with hearing loss.

Some are available with automatic shut-offs, while others automatically shut down if they detect enough drained water from them.

Whatever blower you choose, you can be sure it will be a valuable asset to your Spa experience.

Do Spa Jets Need Air?

Yes. And the air needs to be clean and free of dust particles.

“Jets of the Spa can generate a lot of dust within the water, clog filters,” says Peter Treadway, Water Quality Testing Lab president. “It can also coat surfaces with a film that sticks around.”

That’s why it’s essential to have your filter checked regularly and replaced regularly—at least every couple of months.

After all, a clean filter is an efficient one. It also helps to have your impeller checked to ensure no holes.

Clean filters and impellers also can help extend the life of your jets. Without them, jets may leak air and jam up over time.

And if you use your Spa regularly, you can enhance the jets’ performance by closing the cover, keeping them warm and moist.

If you leave them uncovered in freezing weather, they could crack or break off during the subsequent use.

If you have doubts about whether or not to replace your jet, the answer is probably yes.

“You can clean them, but that process is difficult and often not cost- or time-effective for a consumer,” says Treadway. “When in doubt, replace.”

How Big Of A Spa Blower Do I Need?

It would be best to have a Spa blower for circulating and purifying the air in your hot tub or Spa.

The type of blower you need will depend on the size of the Spa or hot tub that you want to clean.

Various options are available, including models that operate on either electricity or by blowing air through hoses and attaching directly to a swimming pool’s filtration system.

Purchasing a Spa blower can be confusing as so many models are available.

The answer to how big of a Spa blower do I need depends on the size of the tub you want to blow air through.

The problem is that manufacturers don’t use standard measurements for hot tubs.

So getting a unit that matches the specifications recommended by your hot tub manufacturer is the most important thing to keep in mind when purchasing one.

Hot tubs come in two main categories: Attached or Not attached. An attached hot tub is usually secured to the ground through a foundation, while a non-attached hot tub is portable.

You can use a Spa blower on either type of tub, though you need to be careful when using it with a non-attached hot tub as the air you are blowing might disturb the water in the tub and push it out.

For this reason, we recommend using only a Spa blower that attaches directly to the filter system for a non-attached model.

The number of air openings in a hot tub or Spa filter is one of the most important factors when purchasing a Spa blower.

Since you are blowing air into the tub, the more openings your unit, the greater it’s suction.

A larger difference between suction and ambient (outdoor) air will also make it easier for you to blow out debris from your hot tub.

Larger hot tubs have greater volumes of water than smaller models, so they require more airflow to heat the water.

The diameter of the water pump is a measurement that refers to the amount of air it can move per minute.

Ideally, you should select a Spa blower with a larger diameter than your hot tub’s pump, so it pushes enough air to circulate and heat the water efficiently.

Are More Pumps In A Hot Tub Better?

Yes. More pumps mean more bubbles, which can be as relaxing as hot water.

Depending on the size of your hot tub, you’re going to need a few different sizes and types of pumps.

A good starting point is to buy one medium-sized pump, like a 2HP 220V 1-phase or 240V 1-phase Submersible Pump, to circulate the water and produce some bubbles.

You may also need to invest in smaller pumps for the jets (2HP 3/4HP 220V 1-phase).

If you want even more bubbles, try buying a high-efficiency pump (1.5HP-3HP 220V 1phase or 240V 1-phase).

High-efficiency pumps, also called variable speed pumps, can save you as much as 33% on your monthly electric bill.

You can also buy multiple high efficiencies (variable speed) pumps for your hot tub for extra bubbles or power jets and waterfalls.

Remember that high-efficiency pumps can be a little more costly since they usually cost more than one non-high-efficiency pump.

If you want to see if the water is circulating well and blowing bubbles.

You can use a floating thermometer or a floating hot tub thermometer (which floats on the water, so it’s easy to see from inside the tub).

You can also determine how much current your pump draws with an ammeter.

How Does One Stop An Airlock In A Hot Tub?

You can stop an airlock in a hot tub by following these easy steps.

First, turn off the unit power and open the lid. Once opened, vent air by inserting a long hose with a narrow end that’s about 8″ in diameter into the drain port on top of an airlock.

Ensure it’s inserted about 10″ deep, close all other valves on top of the hot tub and allow time for water to drain from inside.

Then, open the pump valve and run the circulating pump for 20 minutes or so to allow air to escape from inside. After that, close the pump valve again.

You can start your hot tub up again; it should work well.

Remember that even with an airlock in place, the entire startup and running process can still take up to 6 hours; this is standard when dealing with these problems.

If you have no other substitute but to get an airlock out of a hot tub, then please follow these steps:

First, turn off the unit power and open the hot tub’s lid.

Once the lid is open, remove all debris that could cause clogging. You can use a net or a skimmer for this process.

Lastly, our hot water into the drain to let air escape from it.

If you only have to reset your hot tub, then do the following steps:

First, turn off the power to the unit and open the hot tub’s lid.

Once you’ve done that, remove any debris that could cause clogging. After removing that, you need to flush out any loose waste with a garden hose.

Keep on flushing until there doesn’t appear to be much or any of the debris anymore.

Next, open the skimmer and pump valve to drain water into your garden hose.

Then, close the pump valve and open the skimmer one last time while placing a flat-edged tool like a putty knife in between them.

While doing this, ensure you position the tool to block off any water from passing through the drain hole.

One can do this by slightly tilting it towards you to ensure that it’ll touch both valves.

What Does A Blower Do In A Hot Tub?

This is what a blower does in a hot tub. It helps the water circulate better and prevents sloshing. The blower is usually a paddle or a bellow.

You can use a blower in a hot tub to help make the Spa more comfortable for you and your guests. You might even use it for personal hygiene, such as light cleaning or scrubbing above the waterline.

You will typically find them sold with hot tubs from time to time, so you should never have any issues locating one quickly if need be.

The hot tub blower is a fanlike device that sits below the waterline. It helps to keep the water circulating correctly instead of sitting in one spot.

When you plug it in and turn it on, it will usually make a soft humming sound. One can also use blowers to eliminate any excessive sloshing occurring while trying to relax in your hot tub.

The blower is usually a paddle wheel or a spiral tube placed inside the tub in outdoor spas. It would be best to point it at 30 to 45 degrees.

An indoor hot tub does not have an exclusive blower but instead has an exhaust fan with a unique vent for drawing out water vapor.

The exhaust vent will look similar to any other ventilation duct installed in your home, and you can install it in just minutes.

The hot tub’s blower is essential as it prevents sloshing and helps to keep the water circulating correctly without causing too much turbulence.

You can also use it to help you clean the outside of your hot tub and keep your water temperature at a high level, which you will appreciate when you get in and start to get comfortable in your Spa.

Can You Run A Hot Tub Pump Without Water?

Yes. It’s effortless. If you’re not using your hot tub, you can do a few things with it.

  • Fill it with flowers or dirt to beautify your garden.
  • Use it as a decorative fountain.
  • Set up a patio in the backyard.
  • Hide an air conditioner inside the hot tub and keep yourself cool this summer.

So, during the summer, your hot tub is sitting there doing nothing. And you want to use it, but you can’t find water in your home with the air conditioning running.

So, how do you use your hot tub without water?

First, turn off all of the hot tub’s electrical components. Then remove all of the hoses from your pump.

There are four holes for your hot tub cover hoses that connect to the pump. Remove these hoses using a small screwdriver to lift them by the black hose and pull them out.

To make it easier to remove, you can use a pair of pliers and grip the hoses tight near where they attach to the pump and pull them straight up and out of the hot tub.

(If you only have three or four hoses, you can squeeze the remaining one or two together and pull. This makes it easy.)

After removing the hoses, you can start turning the hot tub pump by hand. Using an old towel or a shirt, turn the foot pedal on the pump to ensure no clogs in the lines.

Please fill your sink with water and pour it down the drain to get water into your pump. (You should not run any water through the drain.This can cause leaks. There is also a lid to prevent leaks.)

You should have just enough water in the pump to start the motor. If necessary, you can fill the hot tub and turn on the jets or air jets for a few seconds.

If you have a built-in water filtration system, you may need to fill the hot tub and press the jets for about 15 to 20 seconds to get the pump water-free.

If your hot tub does not have any water in it, you will have to clean out all of the calcium deposits in your pump when you turn it back on.

These are white and may be thick. Use a paper clip or a wire for scratching the calcium from the inside pipes.

You can also use sandpaper on the inside of the pipe if you have trouble getting it out.


A hot tub blower is an essential part of the hot tub pump. The blower helps the water circulate better and slosh less when you’re relaxing in it.

It usually comes with hot tub packages, or at least it did before. If you need to buy one, look for a foot pedal blower.
