It’s so disappointing to discover that your jets are not delivering the amount of pressure they should after a long, tiring day. But you’re not alone here – it’s pretty common with hot tubs.
Luckily, there are some tips and tricks you can apply to increase your spa jet pressure immediately and effectively. Our guide aims to help you with some indispensable information that’ll ensure a safe DIY fix.
How to Increase Spa Jet Pressure?
1. Turn off the waterfall
Turn off your waterfall control valve to escalate the water pressure coming from the jets. Ceasing the water flow from your waterfall helps the jets to collect more compulsion.
2. Open up your air control
Turn on the air valves to increase the number of bubbles you get from the jets. It’ll significantly change the flow from the jets when warm air is added to the system.
3. Turn off the jets not being used
If the spa has multiple jets and you’re not using each one of them, you can choose to turn off the additional jets.
For instance, turn off the jets down at the bottom of your seat when you need more pressure up at the top of your seat.
4. Remove & clean the jet inserts with vinegar
Sometimes the jet inserts are clogged up and maybe it’s just time to clean them. Cleaning the inserts at least 2-3 times a year is ideal.
You can simply take out the inserts from the tub and soak them in white vinegar for a while. Put the inserts back in place again once the vinegar clears away the clogs, stain, and filth.
Note: You can also use some white vinegar to clean the showerheads, faucets, and other hard-to-clean tricky components like these.
5. Single out & replace the loose jet parts
Take a closer look at the jets to single out the loose and damaged pieces.
If you notice any component or fitting within your jets that need a replacement, you may get a substitution for that piece.
The new and tight parts will increase your spa jet pressure.
6. Eradicate calcium content in the pipes
Pay attention to the pH levels in your spa water. The raised pH level can eventually cause scaling in your tub, which means the pipes in the tub will gather up calcium deposits inside, and hamper the expected water flow through your jets.
Tip: Get the “Descaler Solution” from the market, mix it with water to liquefy the tough calcium content in your tub. Use a host filter to fill up your hot tub so it’ll bring down the magnesium and calcium levels.
7. Get rid of the airlock
Inspect if the air is blocking somewhere. Bleed the pipes and valves, or activate the jets for a minute and turn it off to get rid of an airlock right away.
You’ll hear a hissing blare as the air is released from the discharge channel. You might be in trouble if the air is locked for a considerable period.
8. Replace your clogged filter
Pull out and clean your filter cartridges every few weeks. Ideally, you’d replace them once a year. They also cause the jets to slow down on rare occasions.
9. Upgrade the pump
Upgrading to a stronger pump is the ultimate resolution to increase the jet pressure when every other part is working well. The pumps get weary and less effective along with time.
For instance, you need to ensure at least 90 GPM of flow to the manifold if your hot tub has 6 jets and each one pulls 15 GPM.
How to Troubleshoot Your Hot Tub/Spa Jet Effectively?
1. Read your display
The display shows all the basic information or error codes. This is the first thing to do when you’re facing issues with the jets and water pressure.
2. Reset the spa
Turn off the breaker, wait a minute, and turn it back on. Try out the pumps again. Sometimes, your tub gets back on track after a restart.
3. Head to your spa pack
The spa pack is the control system or the brain of the hot tub. Check if the plugs are nice and tight from afar.
You should not touch anything in the spa pack before you turn the breaker off.
4. Check for blown-up fuses after the breaker is turned off
Each pump in your hot tub has a dedicated fuse. You can get a new fuse from the nearest spa store if you find them creating trouble.
Pull out the damaged fuse with needle-nose pliers and replace the new one the same way. The fuses are made of fiberglass so they should be pretty sturdy.
5. Try switching between plug wires
Put the plug for pump 1 to the socket for pump 2, and do the same with the other plug. Return back to the pump buttons and hit them “on”.
Your jets will run fine if it was only a loose plug issue.
6. Make a service call
Your hot tub is a complex machine underneath the water. You may want to have a pro come over to fix your jets if all the quick fixes have left you without a satisfying solution.
FAQs
1. Why are my hot tub jets weak?
Ans. Perhaps your pump is not function ing appropriately, or there is an airlock. You may want to loosen the airlock valve close to the pump to solve the issue.
2. How do inground spa jets work?
Ans. There are two inlets confronting and feeding each jet in the hot tub, one is for water and the other one is for air. The water mixture reaches you through the nozzle in the tub.
3. Why do my hot tub jets keep turning on?
Ans. The jets automatically operate when the water temperature falls below the point you’ve set to. If you set it to 100, the jets will run automatically as the temperature falls to 99.
4. How often should you purge your hot tub?
Ans. Purge your hot tub every 2-3 months depending on the usage and conditions. You should not let more than 3 months pass by. If you’ve just got a new unit, it’s a good idea to go for a purge before you use it.
5. Can you take jets out of the tub?
Ans. Yes, you can! You can use your hands to turn the jet nozzles aside and pull them out one by one to clean and replace them. Also, you’ll find tools available in the market to help you with this task.
6. How does air get into spa jets?
Ans. There is an inlet of air along with a water inlet for each jet of your tub. Air gets in through this inlet. Water and air get mixed and come through the nozzle to the tub.
7. How do you control a spa jet?
Ans. In some master spas, there is an outer ring on the jet to control the water flow. To increase the water pressure you can turn the outer ring clockwise and to stop the flow turn it counterclockwise.
8. Can hot tub jets get clogged?
Ans. Yes, but it is not a frequent phenomenon. A small broken piece or calcium clumps or other debris can be the cause of this blockage. Calcium or debris can be pushed through the filter and small pieces can lodge in the jets.
9. Should hot tub jets always be on?
Ans. Absolutely yes. The design of a hot tub is made keeping this fact in count that it will be on for all time. Moreover, the hot tub works better and more efficiently if it’s on 24/7.
