Can You Run Pool Pump If Water is below Skimmer

Yes, you can run your pool pump if the water is below the skimmer. Pool pumps are designed to move water from one place to another and will generally work even when the level of water in a swimming pool or spa is lower than normal. It is important to note that running your pump with very low levels of water could cause damage to it due to lack of lubrication and increased pressure on internal components.

Additionally, having low levels of water could also lead to cavitation which occurs when air bubbles form inside the motor as a result of insufficient liquid present for cooling purposes. Therefore, it is recommended that you should always check the manufacturer’s instructions before operating a pool pump with low levels of water and take necessary steps such as adding more make up water if required.

  • Check the water level in your pool: Before attempting to run your pool pump, you must make sure that the water is at least above the skimmer
  • If it is not, add additional water from a garden hose until it reaches this level
  • Turn on the power to the pump: Locate and turn on any breakers or switches associated with your pool pump motor so that it has electricity running through it
  • Place priming plug in its correct position: Unscrew and remove the priming plug located near your skimmer basket to ensure proper suction of air-free water when starting up for operation
  • Fill up shaft seal chamber with clean water: With a bucket of fresh clean water, fill up both sides of shaft seal chamber which you should find inside your filter housing where all piping comes together before entering into circulation loop system around swimming pool area/equipment pad area (if applicable)
  • 5 Run Motor – Start Up Pool Pump : Finally, press down firmly on switch or button found either on top panel part of electric motor control box itself or beside equipment pad depending on type/model used by yourself as homeowner; keep an eye out for pressure gauge needle movement towards right side once power gets turned back ON followed by sound change coming out from inside electric motors themselves if everything works properly & proceeds according to plan!

How to run pool pump if water is below skimmer- step by step

Let’s drive you into the process.

Step 1: Assess the Water Level

The first step in running your pool pump when the water is below the skimmer is to assess the water level. Grab a yardstick or a similar measuring tool to determine the current water level in your pool. 

The skimmer, which is responsible for collecting debris and sending it to the filter, should ideally have the water level halfway up its opening. 

This ensures that the skimmer can function properly and maintain efficient filtration. Take the measurement and note the current water level for reference.

Step 2: Add Water to the Pool

If the water level is below the optimal halfway point of the skimmer opening, it’s essential to add water to the pool before running the pump. To accomplish this, you’ll need a garden hose and a water source. 

Connect the garden hose to the water source, such as an outdoor faucet, and place the other end into the pool. Turn on the water source and allow the hose to fill the pool gradually. 

Keep a close eye on the water level, aiming to raise it to the halfway point of the skimmer opening. 

The time required to fill the pool will depend on various factors, such as the size of the pool and the water pressure, but it’s important to ensure the water level reaches the desired level.

Step 3: Prime the Pool Pump

To ensure optimal performance, it’s crucial to prime the pool pump before running it. Priming involves removing any air trapped in the pump and creating a steady flow of water. 

Locate the pump’s lid, typically found on top of the pump housing. Unscrew the lid and pour water into the pump until it fills the chamber completely. 

This water helps eliminate any air and provides a smooth operation. The amount of water required for priming may vary depending on the pump’s size and design, but a good rule of thumb is to fill the pump chamber to its capacity. 

This step ensures that the pump is ready to efficiently circulate water.

Step 4: Close the Skimmer Valve

Given that the water level is below the skimmer, it’s necessary to close the skimmer valve. The skimmer valve controls the water flow from the skimmer to the pump. 

Locate the valve, typically situated near the pool equipment, and turn it to the “Closed” position. By doing this, you prevent air from entering the pump and ensure a proper water flow. 

The skimmer valve closure should be a simple twist or turn motion to shift it into the closed position. With the skimmer valve closed, the pump will draw water solely from the main drain instead of the skimmer.

Step 5: Open the Main Drain Valve

With the skimmer valve closed, it’s time to open the main drain valve. The main drain serves as an alternate water intake located at the bottom of the pool. 

Locate the valve, usually near the skimmer valve, and turn it to the “Open” position. This action allows the pool pump to draw water from the main drain instead of the skimmer. 

By using the main drain as the water source, you ensure that the pump continues to circulate water, even with a low water level in the skimmer. 

Opening the main drain valve should be a straightforward movement, typically achieved by rotating the valve handle to the open position.

Step 6: Turn On the Pump

Now that you have prepared the pump and adjusted the valves, it’s time to turn on the pool pump. Locate the pump’s power switch or control panel, which is usually near the pool equipment. 

Activate the pump by flipping the switch or pressing the designated button on the control panel. Once the pump is running, you should notice water flowing through the pump and into the filter system. 

The pump’s motor will generate the necessary force to circulate the water through the filtration system, aiding in debris removal and maintaining water clarity.

Step 7: Monitor the Water Flow

While the pump is running, it’s important to keep a close eye on the water flow to ensure everything is functioning correctly. 

Observe the water as it enters the pump and passes through the filter system. You should notice a steady flow of water, indicating that the pump is operating efficiently. Additionally, check the pressure gauge on the filter system. 

The gauge measures the pressure inside the filter tank and should display a consistent and normal pressure range. If the pressure is too low or too high, consult your pool’s user manual or contact a professional for assistance. 

Regular monitoring of the water flow and pressure helps to identify any potential issues and ensures proper pump operation.

How to Drain a Pool Using the Pool Pump

To drain a pool using the pool pump, start by shutting off the power to the pump. Then, attach a garden hose to your skimmer and run it out of the area you are draining your pool into. Next, open up all of the valves that allow water out of the filter system and turn on your pool pump.

As soon as water begins flowing through your garden hose, you can be sure that your pool is draining properly. Make sure to keep an eye on levels while draining so they don’t get too low or become unbalanced!

How Long Can You Run a Pool Pump on Recirculate

A pool pump can be run on recirculate for as long as you need, with no set limit. However, it is important to monitor water quality and ensure that circulation levels are adequate. If running a pump on recirculate for extended periods of time, it’s advisable to check the filter regularly and clean or replace if necessary in order to avoid any potential problems.

Pool Main Drain Valve Open Or Closed

When it comes to pool maintenance, knowing whether or not the main drain valve should be open or closed is an important factor. Generally speaking, when you are cleaning your pool and doing any type of maintenance work such as vacuuming or brushing, the main drain valve should be left open. This ensures that debris collected from inside the pool is able to escape through the drain line and does not accumulate in the filter system.

On the other hand, when swimming in your pool for recreation purposes, make sure to close off this valve before getting into the water as it can create a suction hazard if left open while swimmers are present.

Running Pool on Main Drain Only

Running a pool on the main drain only is an effective way to maintain your pool’s filtration system. This method allows for more efficient circulation of water, resulting in cleaner water and better overall hygiene. Additionally, running a pool on the main drain only reduces wear and tear on your filter system by eliminating the need for backwashing or other manual cleaning tasks.

Finally, this approach can save you energy costs as it reduces unnecessary filtering that would otherwise take place with multiple drains open at once.

How to Drain Inground Pool

Draining an inground pool is a necessary step every few years in order to ensure the longevity of your pool. To drain your pool, you’ll need to turn off all power sources connected to the pump and filter. Then locate and remove the plug from the bottom of the skimmer box or suction line, which will allow gravity to pull out most of water from your pool.

After removing as much water as possible this way, you may need additional pumps or hoses to finish draining it completely. Finally, once all of the water has been removed, be sure to refill with fresh clean water before turning on any electricity source back on!
