How to Increase Pool Pump Pressure?
If your pool pump loses pressure (PSI), then the water will not flow through the filtration system at the rate it was designed for, and the pool water will not be filtered or cleaned as needed, resulting in a loss of electrical power and a significant loss of process pool water. The swimming pool is dirty.
The pool's pressure reading is a great monitoring tool for pool operators and can be used intuitively to keep pool pumps and filtration systems running cleanly and effectively reduce chemical and electrical costs and prevent downtime while maintaining maximum exposure. How to increase pool pump pressure? Read on to learn more.
Normal Pool Pump Pressure
The best way to determine the normal pump pressure for your filtration system is to start with:
- After cleaning the filter and basket in the pool and the pump screen.
- After adding new media and recording the system's PSI on the gauge.
- After purchasing a new filter element or sand filter.
Normal pressure for most pools varies, ranging from 5-15 psi or 10-25 PSI. Filtration system pressures depend on the type of filter, size of piping, size of discharge in the pool or pump, and other pool equipment. After running for a while, the filter will start to clog with debris, grease or hair that the filter removes.
You will see the pressure on the filter gauge rise as PSI and the flow slowly decrease as pool water returns to the pool. If your pool has a spa mode that returns pool water to different locations and different size pipes, you should see a rise in pressure. Therefore, you will need to note or document this PSI as your spa's normal starting pressure.
High pressure is considered to be 5-10 PSI higher than the pressure reading at startup or usual cleaning. For example, when you have a clean filter, you know your pool typically runs at 13 PSI. If you're running 20 PSI right now, you know the pressure is high and something's not right. As a pool operator, you are best able to judge when to backwash a sand filter or open a cartridge filter for cleaning. Both filters need to be inspected for damage every season.
Take a Sharpie and mark the cleaned operating range on the filter's gauge so you can visualize where the normal PSI should be. Check to make sure the PSI gauge is not stuck or damaged by flicking it and making sure the needle moves. If damaged, use Teflon tape on the threads to replace it.
A dirty filtration system will increase the PSI on the gauge while reducing the flow back to the pool. Typically, the manufacturer recommends that you backwash after the PSI has reached about 10 pounds above the cranking pressure.
Reducing pool pump pressure can:
- Low filtration efficiency
- Reduced water turnover
- The electrical efficiency of the pool pump motor is low
- Add work
Low Pool Pump Pressure
The pool pump is the device that returns the vacuum to the pool through the filter Low flow back into the pool.
This is easy to recognize by checking the PSI on the filter gauge daily when you first come into your pool area for testing and cleaning maintenance. If you see low pressure here, here are a few things to check:
- The easiest to check is the skimmer basket, which is likely to be clogged with leaves or other debris.
- A clogged strainer basket on the pump will cause a low-pressure reading and reduce flow - pull the strainer basket and clean out debris.
- A clogged pump impeller reduces pressure and reduces suction and reduces flow through the pool pump - Open the pump screen to access the impeller and clean debris, usually hair, that ends up trapped in the impeller, preventing it from spinning, thereby Creating a vacuum in the system. Turn the pump off and power it on. Turn the pump on and clear the blockage, check by spinning the impeller.
- A clogged filter reduces pool pump pressure and reduces return flow to the pool.
- Air leak or airlock - Water level below skimmer suction - Add more water to pool at least halfway to skimmer inlet. Check that air is not being drawn into the filter system properly at the pump inlet, pump cover (check gasket and replace), or valve hoses, loosening the pressure gauge on top of the filter allows air to be bled out of the filter system while the filter is running. Also, check dry rot, and frayed filter hoses for cracks and leaks. Replace hoses as needed to maintain a vacuum-tight system.
- Close or partially close the oil skimmer or main drain valve - Shut down the pump and reposition the valve.
- Reinstall the multi-valve - Shut off the pool filter and reinstall the valve of the filter so it is seated properly.
- Sand filter - Needs to be back washed according to the manufacturer's specifications - sometimes you may need to open the filter and check the top layer of sand to remove the scum layer and add fresh sand if needed.
- Cartridge filters - Should be taken offline, rinsed, cleaned, and soaked in TSP solution overnight.
You may have added too many water features to your pool, such as sprinklers and fountains, and the pool pump cannot handle the ever-decreasing pressure. You can turn off some of these water features and check which ones are adding too much extra demand. Add a bigger pump.
