Learning how to pool vacuum to waste might seem a little tricky at first. You might worry about making a mistake or not doing it right. But really, it’s a simple process once you know the steps.
We’ll walk you through it easily so you can get your pool sparkling clean. Let’s see how to get this done without any fuss.
Why Vacuum To Waste?
You might be wondering when and why you would ever need to vacuum your pool water directly out to the waste line. It’s not something you do every time you clean your pool, but it’s a very important tool to have in your pool maintenance toolkit. Think of it as a special move for specific pool problems.
Dealing With Heavy Debris
The most common reason to vacuum to waste is when you have a large amount of debris in your pool. This could be a big leaf storm after a windy day, or perhaps your pool cover wasn’t on tight and a lot of dirt got in. When you have this much gunk, your pool filter can get clogged up very quickly.
If you try to vacuum it normally, all that dirt just goes through your filter and then back into your clean pool water. This is not what you want!
Vacuuming to waste bypasses your filter. This means all the heavy debris gets sent straight out of your pool system and away. It’s like taking out the trash directly instead of putting it in a smaller bin first.
This saves your filter from being overloaded and makes cleaning much more efficient.
After Algae Blooms
Another key situation where you’ll want to know how to pool vacuum to waste is after an algae bloom. Algae can make your pool water cloudy and green. Even after you’ve treated the algae with chemicals, there will be dead algae particles floating around.
These dead particles are very fine and can clog your filter fast. Vacuuming to waste lets you remove these dead algae cells without clogging up your filter. This helps get your pool water clear again much faster.
Lowering Water Level Quickly
Sometimes, you might need to lower your pool’s water level. Maybe you’re doing repairs, or perhaps the rain has overfilled your pool. Vacuuming to waste is a fast way to drain water from your pool.
It’s much quicker than just letting it evaporate, especially if you need to lower the water significantly.
Understanding Your Pool’s Plumbing
Before you can vacuum to waste, you need to know a bit about how your pool’s plumbing works. Most pools have a system called a multiport valve. This valve is usually attached to your pool pump and filter.
It controls where the water goes.
The multiport valve has different settings. These settings are typically labeled on the handle of the valve. Common settings include:
- Filter
- Backwash
- Rinse
- Waste
- Recirculate
- Closed
When you set the valve to “Waste,” you’re telling the water to go directly from the skimmer or main drain, through the pump, and then out the waste line. This bypasses the filter entirely.
The Filter Pump
Your pool’s filter pump is the heart of your circulation system. It pulls water from the pool and pushes it through the rest of the system. When you vacuum, your vacuum head connects to the skimmer or a dedicated vacuum port.
The pump then pulls the water and debris through the vacuum hose.
The Multiport Valve Settings
Let’s look closer at the settings on your multiport valve. Each one has a specific job:
- Filter: This is the normal setting for everyday use. Water goes from the skimmer to the pump, then through the filter, and back into the pool.
- Backwash: This setting reverses the water flow through the filter to clean it. You’ll see dirty water going out the waste line when you backwash.
- Rinse: After backwashing, you use the rinse setting for a short time to settle the filter media and send any remaining dirty water out the waste line.
- Waste: This is the setting we’re focusing on. Water goes from the pool, through the pump, and directly out to waste.
- Recirculate: This setting bypasses the filter but circulates water. It’s sometimes used to distribute chemicals quickly without filtering.
- Closed: This setting shuts off all water flow. You only use this when you’re performing maintenance on the pump or filter.
Always make sure your pump is off before you move the lever on the multiport valve. Moving it while the pump is running can damage the valve and the pump.
Steps For How To Pool Vacuum To Waste
Now that you understand the “why” and the “how” of your equipment, let’s get to the actual steps. Following these steps will make the process smooth and effective.
Step 1 Gather Your Supplies
Before you start, make sure you have everything you need:
- A good quality pool vacuum head
- A telescoping pole for the vacuum head
- A strong, long vacuum hose
- Your pool’s multiport valve handle
- A way to monitor your pool’s water level if you’re draining a lot
Step 2 Prepare The Vacuum Hose
This is a crucial step that many people miss. You need to get all the air out of your vacuum hose before connecting it to your skimmer.
Here’s how to do it:
- Lay the vacuum hose out on the pool deck or ground.
- Find one end of the hose.
- Submerge that end of the hose into the pool water. Let water start filling it naturally.
- Once water starts coming out the other end, you know it’s filling up.
- Continue to let water fill the hose until it is completely full of water and no air bubbles are coming out of the end you are holding.
This process removes air, which is important because air can get sucked into your pump and cause it to lose prime. Losing prime means the pump can’t push water and can be damaged if run dry.
Step 3 Connect The Vacuum Hose
Once your hose is full of water, connect the free end to your pool’s skimmer. Most skimmers have a designated port or an opening where the hose can be securely placed. Make sure it’s a good fit so it doesn’t get pulled out during vacuuming.
If your pool has a main drain and you want to use that, you might need a vacuum plate to cover the drain and create a suction point for your hose. However, most people use the skimmer.
Step 4 Set The Multiport Valve To Waste
This is the key step for vacuuming to waste. Remember to turn OFF your pool pump first.
Go to your multiport valve. Find the handle. Push the handle down to unlock it and then move it slowly to the setting labeled “Waste.” Once it’s in place, let the handle lock into position.
Ensure the valve is fully in the Waste position. If it’s not set right, you won’t be vacuuming to waste, and you could end up sending debris through your filter or causing other issues.
Step 5 Turn On The Pool Pump
With the multiport valve set to Waste and the vacuum hose connected, you can now turn your pool pump back on. You should see water being drawn through the skimmer and into the vacuum hose. The pump will be pushing this water out of your pool system through the waste line.
Step 6 Begin Vacuuming
Now, take your vacuum head and pole and carefully lower it into the pool. Move the vacuum head slowly across the pool floor. Treat it like you’re vacuuming your carpet.
Work in long, overlapping strokes.
Move slowly enough to pick up all the debris, but not so slowly that you disturb the water too much. The goal is to gently pull the debris into the hose. You’ll see the water and debris being sucked up the hose and out of the pool.
Keep an eye on your pool’s water level as you vacuum. If you’re draining a lot of water, you might need to turn off the pump periodically and add fresh water to prevent the skimmer from sucking air. This is especially important if you’re not trying to lower the water level significantly.
Step 7 Monitor And Continue
Continue vacuuming until you’ve cleaned the entire pool floor. Watch the water coming out of your waste line (if you can see it) or just feel the suction at the skimmer. You’ll know you’re done when you’re not picking up much debris anymore.
Periodically, you might want to check your filter pressure gauge (if you have one). However, since you’re bypassing the filter, the pressure won’t be an indicator of filter cleanliness in this mode.
Step 8 Turn Off The Pump and Reset The Valve
Once you’ve finished vacuuming, it’s time to turn everything back to normal.
- Turn OFF your pool pump.
- Move the multiport valve handle back to the “Filter” setting.
- Turn your pool pump back ON.
Now your pool is circulating water normally through the filter again. You’ve successfully learned how to pool vacuum to waste.
Step 9 Check Water Level and Add Water If Needed
After vacuuming to waste, your pool’s water level may have dropped. Check the water level. If it’s too low (below your skimmer opening), you’ll need to add fresh water to bring it back to the normal operating level.
This is usually halfway up the skimmer opening.
Important Considerations and Tips
Knowing how to pool vacuum to waste is great, but here are some extra tips to make it even better:
- Hose Length: Make sure your vacuum hose is long enough to reach all parts of your pool, including the deep end and any steps.
- Pump Strain: Vacuuming to waste can put a bit more strain on your pump if you’re sucking up a lot of large debris. Keep an eye on your pump for any unusual noises.
- Water Loss: Be mindful of how much water you’re losing. If you’re not trying to drain the pool, you may need to add water as you go or right after.
- Filter Cleaning: After vacuuming to waste, it’s often a good idea to give your filter a good backwash to ensure it’s clean for normal operation. This removes any fine debris that might have gotten past the initial bypass.
- When Not To Use: Avoid vacuuming to waste for routine cleaning of small amounts of dirt or leaves. Use your normal filter setting for that to conserve water and keep your pool circulating correctly.
Frequently Asked Questions
Question: How long does it take to vacuum to waste?
Answer: The time it takes varies greatly depending on the amount of debris you need to remove and the size of your pool. For heavy debris, it could take an hour or more. For minor algae cleanup, it might be quicker.
Question: Can I damage my pool pump by vacuuming to waste?
Answer: Yes, you can if you’re not careful. If the skimmer sucks air because the water level gets too low, the pump can lose prime and run dry, which can damage it. Always ensure the skimmer stays submerged.
Question: How much water will I lose vacuuming to waste?
Answer: You will lose as much water as you vacuum. If you vacuum for 30 minutes and your pump moves 50 gallons per minute, you’ll lose about 1,500 gallons of water.
Question: What if my pool filter has a different type of valve?
Answer: Most in-ground pools use a multiport valve. If you have an above-ground pool with a cartridge filter, it might not have a “waste” setting. You may need to manually drain it or disconnect hoses, which is less convenient.
Question: Should I vacuum to waste after adding pool chemicals?
Answer: Generally, no. You want your chemicals to circulate through the filter and the entire pool to work effectively. Only vacuum to waste for specific issues like heavy debris or algae that you want to remove directly.
Final Thoughts
Learning how to pool vacuum to waste is a smart skill for any pool owner. It helps you tackle big messes like heavy debris or algae blooms without overloading your filter. By following the simple steps of preparing your hose, setting your multiport valve correctly, and vacuuming slowly, you can effectively remove unwanted gunk from your pool.
This method saves your filter and gets your water clear faster. Remember to always turn off your pump before changing valve settings and to check your water level afterward. You’ve got this!
