Why Is My Hot Tub Gurgling?(Guide)

Why Is My Hot Tub Gurgling?

Why Is My Hot Tub Gurgling?

Hot tub gurgling is mainly caused by air displacing water due to clogging of vents or even the drain. The gurgling will normally be heard underneath your bathtub. This needs instant diagnosis to ensure timely fixing of the problem. Additionally, outdoor wood decks resonate at low frequency, sounding like a constant drone.

Clogs in the drain or vents cause considerable problems unless they are addressed in time. 

This noise can be amplified when conducting through nearby fences or reflecting off exterior walls.

This can be corrected by cutting the wood deck to fit the Spa, using a 4″ thick reinforced concrete slab on which the spa can rest.

The vents need to be cleared first to address the air moving through the P-trap. This might call for disassembling the part of the vent cover and then cleaning underneath it.

You will need to use a handheld vacuum cleaner and wear gloves to reach the inside vent without getting injured.

Hot tubs are not very different from automobiles. And just like cars, if your hot tub is making gurgling noises, you will want to take notice of that.

Gurgling noises are too common in a hot tub. As you might expect, it might affect the peace at home and harmony with neighbours. This is especially so if the noise is too loud.

Indeed, neighbors might launch complaints due to your noisy hot tub. Fortunately, this noise can be reduced, saving the friction with neighbors and relatives at home.

Can You Upgrade Hot Tub Jets?

Yes, Hot tub jets can be upgraded. As you know, jets are an excellent way to relax and wound up after a long day’s work.

But you need a perfect combination of jets to get that kind of relaxation from your hot tub. The perfect assortment of jets will massage and sooth your body and mind.

Once you upgrade your hot tub jets, it’s not uncommon to forget all your troubles once you enter the hot tub due to the soothing sensation you receive therein.

We know that not all hot tubs come with jets. Luckily, some hot tubs allow you to add jets. However, this can only be done appropriately by a professional.

Can You Plug The Jets In A Jacuzzi Tub?

This is because it’s a process that might also encompass the installation of more pumps.

But if your hot tub doesn’t have jets, you can turn it into a masterpiece, although there are many things to consider. Indeed, you can’t just screw on a jet and expect it to work.

There are scores of mechanical aspects and other issues you will face when trying to transform your hot tub.

Many people love jest in their hot tubs to the point that they want more jets.

While this is a possibility, you want to consider the financial implication associated with adding jets to a hot tub. For the extra jets to be handled, they need an extra pump.

Unless you install more jets, the existing jets might not work well since their efficiency might be affected.  

Why Are My Hot Tub Jets Weak?

Many factors might be behind hot tubs’ under performance. Therefore, it’s essential to rule out variables at random to realize a solution.

Some of the most causes of weak performing jets include worn filters, obstructions, no pressure, and gasket malfunctions.

It’s normal for jets with old filters to slow down, pulsate and soften. Filters need to be removed from the jets to be tested.

The filters can be changed, but you can first clean them and re-insert them.

When it comes to obstructions, your jets will easily clog if a bearing loosen. Again, torn hair can impede the impeller, so you want to check for such obstructions.

However, there might be some scale deposits if you can’t see any clogs.

Lack of pressure can also be a problem, especially after draining your hot tub. This happens due to hair locks that develop in the pump.

This cause the pump to lose traction and weaken. Luckily, you can do these pump repairs without the help or need of a professional.

A jet cannot be complete without including an internal gasket designed to separate high and low water pressures.

Without a properly functioning gasket, the gasket can’t draw air correctly. Consequently, its streaming will be soft and inconsistent.

You can solve this by buying new gaskets and making the needed replacements.

Are Hot Tub Jets Interchangeable?

Yes, Most hot tub jets are interchangeable. Indeed, most hot tub manufacturers make their inserts, but the ‘body’ is the same between several manufacturers.

This means you can swap jets from one hot tub to another. Consequently, jets of the same size are interchangeable, regardless of brand or make.

To remove a jet, you need to turn it to the left, and it will pop up.

To interchange a jet, you must turn off the jet first. After this, get hold of the outside edge of the damaged water jet. On a level surface, place your water jet face down.

Holding the jet in place is a flexible tub design that many jets have.

Spas out there are in the $1,500 – 3,000 range that will serve you marvelously!

They will probably have around 12-20 jets, but they should be strategically placed so if you want the massage, you can have it.

But you might be wondering what might occasion the need to change jets. Premature jet failure can be linked to chlorine in most instances.

While chlorine kills microbes and dissolves organic material, chlorine is behind jet bodies getting brittle. When plastic gets brittle, you know it breaks, so the jets pop out after breaking.

Can You Plug The Jets In A Jacuzzi Tub?

Yes, You can plug jets in your Jacuzzi tub. While many people love their Jacuzzi with jets, you might want to have it easy without jets in your hot tub.

If you feel that jets annoy you instead of offering the relaxation you need, you can turn them off by twisting them counterclockwise. Alternatively, you can put covers or plug on the jets.

Plugging your Jacuzzi jets can be done by hiring a professional, although you can still do it. Indeed, there are so many options that it gets hard to decide which way to go.

Choosing a professional for the job will assure you that the task will be performed at standard and professional levels.

This is better compared to what you can do, but there is a cost to meet. And it might not be some mean amount of money as it may cost a lot of money to do that.

Therefore, before rushing to call professionals for the task, it’s best first to see if you can do it.

For instance, establish if any arrows indicate which way the jets should be twisted to turn them off and on. It might get tricky to put caps on the jets.

But remember that not all hot tubs will have jets that can be turned off this way. So, if you can’t find any arrows, try twisting them to see if they will turn off.

If they don’t, try the other options discussed above.

How Do You Plug A Jet In A Jetted Tub?

If you have a jetted tub and it’s too noisy, you might consider plugging it. Plugging a jetted tub is one of the blessings you might enjoy if you have jets.

Again, if your motor seized and you are one of those guys keen on their expenses like me, you know it’s cheaper plugging your jets than the costly repairs.

Although jetted tubs are a great luxury for any bathroom as they can help soothe muscle and joint pain, jetted tubs do not always have to remain jetted.

Luckily, closing the jetted tubs can be a quick fix. As you might know, the jetted system is tasked with pulling in water from the bath and sending it to the motor driving the pump.

After this, the water is pumped out to the jets. From the jets, the water comes out with enough pressure to soothe muscle aches, creating the bubbling current bathers enjoy so much.

A nozzle can be used when plugging a jet in a jetted tub. If you observe a jet nozzle keenly, you might identify an arrow or another indicator.

This will indicate what you need to do to turn off the nozzle. However, you are advised to turn the nozzle gently. Once you turn off the jets, you might want to check for leaks.

On the other hand, you can disable the system completely.

There is an option that some homeowners use detaching the nozzles and installing caps over the openings as this disables the system completely.

But it’s never easy to find plugs that will fit where the jet nozzles were.

How Do I Know If My Hot Tub Has A Jet Leak?

Identifying a small leak might not be as obvious as with big hot tub leaks. Indeed, all you might notice is your hot tub’s water level dropping.

When your jets are leaking, water pooling around the base of the hot tub when the jets are on is an indication that your jets might be leaking.

While hot tubs generally leak at the pump and the union fittings on either side of the heater tube, removing the panels will enable you to spot where water is pooling the most.

Before you call a professional to fix a leak, I recommend you check to see if your hot tub is under warranty. Hot tubs in warranty will have their leaks repaired by a professional for free.

However, if you are uncovered, small leaks around the jets can be fixed easily by Marlig Fix-a-Leak, as it works great.

Unfortunately, it will not work if you have worn gaskets or (especially) cracked PVC pipes.

How Do You Find A Leak In A Jacuzzi Tub?

The easiest way to find a leak in a Jacuzzi tub is to call in a professional plumber to find and fix the problem for you.

Unfortunately, plumbers are not cheap, and you might not be willing to pay their hefty charges.

When seeking to find leaks in your Jacuzzi, the first thing you can’t forget is to switch off the power supply.

If the leak is too close to the pump motor for the tub, you might risk shock or injury.

Start by checking the union fittings underneath your hot tub. Essentially, vibrations in a Jacuzzi tub can cause union seals to shake loose and leak.

You will need to crawl space under your tub and check to ensure they are tight.

Avoid using a pipe wrench to tighten union fittings by a hand.

But if they are too hard to turn using your hand, you might need to loosen the mounting bolts on the pump before adjusting the fittings, so they are properly aligned.

Also, looking for leaking pipes is another way of identifying leaks in your Jacuzzi.

Indeed, the PVC pipes are a common source of leaks in a Jacuzzi due to expansions that lead to cracks in hot and cold temperatures.

Another place to look for leaks in your Jacuzzi is on the valves. You only need to inspect them to see if they are occasionally leaking.

Can You Put Food Coloring In A Hot Tub?

Yes, You can put food coloring in a hot tub. Over the summer, you can save empty milk jugs and other plastic containers.

After filling them with water, freeze them and toss them into the hot tub like giant ice cubes.

Proceed to add food coloring to the water in your jugs, as adding little color and fun to your hot tub is a welcome idea.

One of the most enjoyable parts of your life is formed by hot tubs.

And if you need more enjoyment out of your hot tub, you can add some things to your hot tub water to enhance your pleasure and get therapeutic benefits.

Interestingly, such additions rarely affect the water chemistry and therefore cause little to no effect on your hot tub or hot tub covers.

This is because food coloring is not made of any acids.

Indeed, you will find that it’s normally made of bases or neutral additives that will not affect your hot tub water chemistry.

Food coloring can be added to your hot tub water to turn it green, yellow, red or any other imaginable color. You will find these worthy for special events.

Such events include birthday parties, wedding parties, and family get-together parties.

How Much Does It Cost To Replace A Circulator Pump?

Replacing a circulator pump will take back some $400 on the lower side. However, a decent circulator pump replacement can cost $750 or more if you consider the parts and labor.

The circulator pump will cost you between $100 and $300. But this will depend on the model your system needs.

While the consumer can easily install some circulatory pumps, some will require a professional plumber to be installed well.

These are the ones with complex designs and connections.

Although replacing a circulatory pump might seem complete once you are done, there are other costs replaced to the replacement that you need to consider.

For instance, the two variable costs you don’t want to forget are the energy used by the pump and the additional water heating required.

Still, you will also want to consider the electric bill associated with your replacement, especially if you get another pump whose specs are different.

Luckily, a correctly installed heating system will guarantee a long time with your new pump.

Why Won’t The Circulating Pump Work After Changing Water

If your circulating pump doesn’t pump water after changing water, there are several things you can suspect.

For instance, you might have a clogged filter, lost prime, airlocks and pump problems.

You might be aware that for your hot tub to thrive, it relies on air circulation that forces water to move around the system.

When your pump gets the water from the tub and pumps it through the heater, filter, and heater, it shoots it into the tub through the jets.

This is a repeat action that might be repeated several times. But we know there will be a time to drain your hot tub, just like many other owners.

When you do this, your pump might fail to pump water due to lost prime. An airlock is unfriendly to your hot tub and will cause your pump not to perform its functions.

An air-lock usually comes from the impeller’s action of driving the water in the housing back into the tub when the pump starts, creating a vacuum in the housing.

This vacuum pulls more water from your tub via the suction line. As you drain the tub, the chances are that you might also drain the pump housing.

This will cause the pump to lose its prime and get airbound.

Pump problems can also make it not work after changing the water. This is because draining the tub might have exposed problems with your pump.

But if your pump hums briefly and then shuts down, debris might be the cause. See if there is clogging on your impeller or if you have a broken impeller altogether.

However, you can’t do this until you disconnect your power supply.

Still, valves can be the culprit, as some pumps require you to close valves on your pump’s intake and outflow before you can drain the hot tub.

If you forget to do that, you can expect your pump to fail after changing the water.


Your hot tub will gurgle due to water displacement that results from clogging.
