Keeping a pool clean requires more than just skimming the surface. One essential maintenance task is vacuuming, which helps remove debris settled on the pool floor and walls. However, many pool owners and even some professionals wonder: when vacuuming, should you set the valve to the filter position or the waste position? Each setting has its purpose and consequences, so knowing when to use each can protect your pool system and maintain crystal-clear water. This article explores the differences and guides you to make the best choice.
What Happens When You Vacuum in the Filter Position?
The filter position is the standard setting on most pool multiport valves. When you vacuum with the valve set to filter, water and debris are drawn from the pool and sent through the pump and filter before returning to the pool.
This process is effective for routine cleaning of small amounts of dirt, leaves, or fine particles.
The advantage of vacuuming in filter mode is that your filter traps the debris, preventing it from returning to the pool. This keeps the water clear and reduces the workload on other parts of your pool system. However, this method also means that all debris passes through the filter, which can clog it faster if the debris load is heavy.
Vacuuming in the filter position is best suited for regular maintenance cleaning when the pool water is generally clean, and only minor debris is present. It keeps your pool looking good without wasting water.
When to Vacuum in the Waste Position
Vacuuming in the waste position means the water you vacuum out bypasses the filter entirely and is discharged directly out of the pool system, usually through a waste line or drain. This setting sends all debris and water straight out of the system.
The primary reason to vacuum in the waste position is when you have a large amount of debris, such as after a storm, heavy leaf fall, or a pool renovation. When you vacuum in this mode, you avoid overloading your filter with debris that can quickly clog or damage it.
Vacuuming in waste mode also helps lower the pool water level if it is too high. Since water is being removed with the debris, it can be an effective way to control water levels without using a separate pump or hose.
The downside is that vacuuming in waste mode discards pool water, which means you will need to top off the pool afterward. Despite this, it is often the safest choice for heavy debris removal and protecting your filter system.
How to Decide Which Setting to Use
The decision to vacuum in filter or waste depends mainly on the amount and type of debris, the condition of your filter, and your goals for water conservation.
-
Light Debris and Routine Cleaning: Vacuum in the filter position. This keeps the water in circulation and ensures debris is trapped inside the filter for easy removal during backwashing.
-
Heavy Debris or Dirty Pool: Use the waste position. Sending heavy debris directly out prevents filter clogging and reduces the frequency of backwashing.
-
High Water Levels: If the pool water is above the optimal level, vacuuming in waste mode can help lower it while cleaning.
-
Filter Condition: If your filter is older or prone to clogging quickly, vacuuming in waste mode when heavy debris is present can prolong its life.
How Vacuuming Affects Your Pool System
Vacuuming is more than just cleaning the pool surface; it impacts your entire pool circulation and filtration system. Vacuuming debris through the filter can cause the filter to become dirty and reduce water flow, leading to increased pressure and less effective filtration.
Conversely, vacuuming in waste mode can put additional strain on your water supply as it requires replenishing lost water. It is also important to ensure your waste line or drainage system can handle the water volume being discharged without causing problems.
Properly managing your vacuuming method helps maintain pump efficiency, filter health, and overall water quality. This can reduce the workload on your pool equipment, extending its life and improving the swimmer experience.
Tips for Effective Vacuuming
No matter which valve position you choose, effective vacuuming requires some basic steps:
-
Check Your Equipment: Ensure your vacuum head, hose, and pole are in good condition and free from cracks or leaks.
-
Prime the Pump: Remove air from the vacuum hose before starting to avoid loss of suction.
-
Vacuum Slowly: Move the vacuum head slowly across the pool floor to allow debris to be properly sucked up.
-
Backwash Your Filter: After vacuuming in the filter position, backwash your filter to remove trapped debris and restore flow.
-
Monitor Pressure Gauges: Keep an eye on your filter’s pressure gauge. High pressure means the filter is dirty and needs backwashing or cleaning.
When to Consult Pool Companies
If you’re unsure about vacuuming procedures or if your pool equipment isn’t performing as expected, consulting professional pool companies can provide valuable assistance. Pool experts can help you determine the best maintenance practices tailored to your pool’s size, equipment type, and environment.
Many pool companies offer regular maintenance services, including vacuuming with the correct valve settings, filter cleaning, and system checks. Relying on professionals can help you avoid costly repairs and keep your pool in peak condition all year round.
Vacuuming your pool is a critical part of maintenance, but the choice between filter and waste position makes a significant difference in efficiency and equipment health. Vacuum in the filter position for light debris and regular cleaning, and switch to waste when dealing with heavy debris or high water levels.
Balancing these approaches will help you keep your pool clean, protect your filtration system, and maintain optimal water quality. If ever in doubt, professional pool companies are a great resource to ensure your pool care routine is effective and hassle-free.
Choosing the right vacuuming position is a simple step that can save time, protect your equipment, and provide a better swimming environment for you and your family.
