It can be tricky when your pool cleaner starts spraying water everywhere it shouldn’t. Many pool owners, especially those new to maintaining their pool, find this a common puzzle. You might wonder why it’s happening or feel a bit frustrated.
Don’t worry, this is something many people deal with. We’ll walk through simple steps to fix this issue and get your pool clean again without the mess. Let’s find out how to stop pool cleaner from spraying effectively.
Why Your Pool Cleaner Sprays Unwanted Water
Seeing water spray out from your automatic pool cleaner can be confusing. It’s not supposed to be a sprinkler, after all! This often happens because of a few common issues.
The main goal of your pool cleaner is to suck up debris, not to shoot water out like a fountain. When it starts spraying, it means something isn’t working quite right with its intended function. This can make cleaning less effective and create a watery mess around your pool.
Understanding the Mechanism
Automatic pool cleaners work by using the water pressure from your pool’s pump. They connect to your pool’s skimmer or a dedicated vacuum line. Water is forced through the cleaner, creating suction to pick up dirt and debris from the bottom of the pool.
Some cleaners also have wheels or jets that help them move around. When these parts are not working as they should, or if there’s a blockage, the water can be redirected and sprayed outwards instead of just creating suction.
Common Causes for Pool Cleaner Spraying
There are several reasons why your pool cleaner might be spraying water. Pinpointing the exact cause is the first step to fixing it. Let’s explore the most frequent culprits behind this problem.
1. Blockages in the Cleaner or Hose
This is one of the most common reasons. If there’s something stuck inside the pool cleaner itself, like a leaf, a small stone, or even a larger piece of debris, it can block the flow of water. This blockage forces the water to find another way out, often through a jet or opening that isn’t meant for spraying.
The same applies to the hose connecting the cleaner to your pool’s system. If the hose is kinked or clogged, it can disrupt the water flow and cause spraying.
Checking for Blockages
First, turn off your pool pump. Disconnect the pool cleaner from the skimmer or vacuum line. Carefully inspect the intake area of the cleaner for any visible debris.
You might need to remove the cleaner’s head or other parts to get a better look. For the hose, try to look through it or gently flex it to see if there are any kinks or obstructions. You can also try running water through the hose to check for clogs.
2. Worn or Damaged Parts
Pool cleaners have moving parts and seals that can wear out over time. If a seal is cracked, torn, or simply old and brittle, it might not be able to contain the water pressure properly. This can lead to leaks and spraying.
Similarly, if any of the cleaner’s jets or nozzles are damaged or misaligned, they might be directing water outwards instead of propelling the cleaner or creating suction.
Inspecting for Wear and Tear
When you have the cleaner disconnected and are checking for blockages, take a close look at all the seals and plastic parts. Feel them for any signs of brittleness, cracks, or tears. Check the cleaner’s head and any attachments for damage.
If you notice any worn-out parts, they might need to be replaced. Refer to your cleaner’s manual for specific part identification.
3. Incorrect Water Pressure
The amount of water pressure going to your pool cleaner is critical. If the pressure is too high, it can force water out of places it shouldn’t go. If it’s too low, the cleaner won’t work effectively, but it can also sometimes cause unusual spraying patterns if other parts are slightly off.
The ideal pressure is usually specified in your pool cleaner’s manual.
Adjusting Water Pressure
Your pool pump has a setting that controls the water flow. You can often adjust this by changing the valve settings on your skimmer or main drain lines. If your pump has variable speed settings, you can adjust the speed.
The goal is to find the sweet spot where the cleaner works efficiently without excessive force. Your pool cleaner’s manual will often suggest a range for optimal water pressure.
4. Issues with the Weir Door (for Skimmer Cleaners)
If your pool cleaner connects to the skimmer, the weir door is an important part. This is the flap that sits in front of the skimmer opening. It’s designed to help regulate the flow of water into the skimmer and keep debris from escaping.
If the weir door is missing, broken, or stuck open, it can affect the suction and sometimes lead to water spraying back out of the skimmer and affecting the cleaner’s performance.
Checking the Weir Door
Make sure your skimmer has a functioning weir door. It should be able to move freely but also create a seal when needed. If it’s damaged, it should be replaced.
Sometimes, adjusting the weir door to a slightly closed position can help improve suction and reduce backflow.
5. The Pool Cleaner Model Itself
Some pool cleaner models are more prone to spraying than others, depending on their design. For example, older models or those with specific jetting systems might have a natural tendency to expel some water. It’s important to consult your pool cleaner’s manual to understand its normal operation and any specific characteristics.
Consulting Your Manual
Your pool cleaner’s manual is your best friend when troubleshooting. It will detail how the cleaner is supposed to work, common issues, and how to fix them. It’s worth rereading the sections on setup, operation, and troubleshooting to see if you’ve missed anything.
Step-by-Step Guide: How To Stop Pool Cleaner From Spraying
Now that we’ve looked at the common reasons, let’s put together a clear plan to address the spraying issue. Following these steps will help you get your pool cleaner back to working properly and stop it from spraying water everywhere.
Step 1: Safety First – Turn Off the Pump
Before you touch anything related to your pool cleaner or its connections, always turn off your pool pump. This is crucial for safety and to prevent damage to the cleaner or your pool’s equipment. Locate your pool’s circuit breaker and switch off the power to the pump.
Step 2: Disconnect the Pool Cleaner
Gently disconnect the pool cleaner from the skimmer or the dedicated vacuum line. If it’s a hose-style cleaner, you’ll need to pull the hose out of the water and detach it from the skimmer. If it’s a robotic cleaner, it will usually just need to be lifted out of the pool.
Step 3: Inspect the Hose and Connections
Examine the entire length of the hose for any kinks, twists, or visible damage. Try to look through the hose to spot any blockages. If you find a kink, try to straighten it out.
If you suspect a blockage, you might need to disconnect sections of the hose (if it’s modular) or try to flush it with water from a garden hose. Check the fittings where the hose connects to the cleaner and to the skimmer for any cracks or debris.
Step 4: Clean the Pool Cleaner Head
Now, focus on the pool cleaner itself. Turn it over and inspect the intake areas. Carefully remove any leaves, twigs, or other debris that might be lodged there.
Some pool cleaners have removable parts, like a debris canister or filter bag, that need to be emptied and cleaned regularly. Make sure these are thoroughly cleaned.
Step 5: Check Internal Components
Depending on your cleaner model, you might need to open it up a bit more. Look for any parts that seem loose, broken, or worn. Pay close attention to any rubber seals or gaskets.
If they look old, cracked, or brittle, they are prime suspects for causing leaks and spraying. Refer to your manual for instructions on how to access and inspect these internal parts.
Step 6: Assess Water Pressure and Skimmer
Once you’ve checked the cleaner and hose, consider the water pressure. If you suspect it’s too high, you can try adjusting the valves on your skimmer or main drain to reduce the flow. Ensure the weir door on your skimmer is functioning correctly.
If it’s stuck or broken, it needs attention.
Step 7: Reassemble and Test
After you’ve cleaned out any blockages and checked for worn parts, reassemble the pool cleaner. Connect it back to the skimmer or vacuum line. Turn on the pool pump and observe the cleaner’s operation.
See if the spraying has stopped. You may need to make minor adjustments to the water flow or cleaner positioning.
Troubleshooting Specific Cleaner Types
Different types of pool cleaners operate in slightly different ways, which can affect why they spray.
Suction-Side Cleaners
These are the most common type. They attach to your skimmer. Spraying from these often means a blockage in the hose, the cleaner head, or a problem with the skimmer’s weir door affecting suction.
The hose can also get a hole in it, causing water to spray out.
Pressure-Side Cleaners
These cleaners use a return jet to create pressure that powers them. Spraying from these could indicate issues with the pressure hose, a damaged return jet on the cleaner itself, or problems with the specific valve that regulates water flow to the cleaner.
Robotic Cleaners
Robotic cleaners are self-contained and don’t rely on your pool’s pump pressure. If a robotic cleaner is spraying water unexpectedly, it’s usually a sign that the internal filter bags or compartments are not sealing correctly, or there’s a crack in the body of the cleaner itself. Their motors and internal water pathways are more complex.
Maintenance Tips to Prevent Spraying
Preventing problems is always easier than fixing them. Regular maintenance can help ensure your pool cleaner works smoothly and doesn’t start spraying.
- Regularly check the pool cleaner for debris.
- Clean out the filter bag or canister after each use.
- Inspect the hose for kinks or holes periodically.
- Check seals and moving parts for wear and tear.
- Ensure water pressure is within the recommended range.
- Store the cleaner properly when not in use to protect it from the elements.
