There are several reasons why you may want to disassemble a pool pump – you may want to repair it, clean it, or just replace a particular component. But regardless of your reason, the main concern is how you do it.
It’s important that you do it the right way so that nothing is at risk, including yourself and those around you.
Before you start taking it down, you need to drain the pool. You can remove the water by using draining hoses or a pool water draining pump. These pumps are readily available for rent at your local pool distributor. If you are using a pump to drain the water, ensure you monitor the entire process to prevent equipment malfunction and flooding.
Also, you cannot start the dismantling process without knowing the type of pump you are working with.
3 Common Types of Pool Pumps
Pool pumps are not universally similar, there are different to suit the needs and preferences of different pool owners from different places.
In the U.S., they are categorized into different groups according to their operational speeds. There are three main types of pool pumps – single speed pool pumps, two-speed pool pumps, and variable speed pool pumps.
1. Single-Speed Pool Pumps
Single speed pool pumps are pool pumps that operate using a single motor. These pool pumps have a fixed operational speed of 3,450 RPMs (revolutions per minute).
These are the most popular pool pumps on the market today because of their affordability. However, single speed pool pumps perform poorly on energy efficiency. It’s recommended that you shut them down when not in use to save on energy bills.
2. Two-Speed Pool Pumps
What distinguishes two-speed pool pumps from single speed pool pumps are the two motors in two-speed pumps and the fact that their operational speeds can be regulated. These pool pumps can operate at speeds as high as 3,450 RPMs or as low as 1,725 RPMs.
They are usually used in small swimming pools and spas.
3. Variable Speed Pool Pumps
With variable speed pool pumps, users are able to select their preferred operational speed. Variable speed pool pumps are the most energy efficient pool pumps available on the market.
They are also affordable compared to two-speed pool pumps, making them quite popular with home pool owners.
How to Take Apart a Pool Pump
- First things first, turn off all the power that goes to the pump’s motor. Make sure you turn it off at the circuit breaker that’s located in the timer box.
- Next, relieve the pressure that may have built up in the pool pump by opening the relief valve. Some water should spray out and the pressure gauge should read zero.
- Now, extract the pumping unit from its housing. You’ll have to remove four bolts (some pumps have six) that bind the unit to the housing and lid. Pull the unit apart from the housing.
- Once the unit is out, you should be able to see the diffuser and its gasket at the end of the unit. The diffuser amplifies the impeller’s pull and creates a vacuum to maximize the power.
- Carefully pull off the diffuser from the unit. It should easily snap off and expose the most of the drive train – the motor, impeller, and impeller ring. You can dislodge these parts to completely take apart the pump.
The motor is the driving force of the pump. It creates the force that pumps and circulates the pool water.
The impeller is the two discs that sandwich the fan blades on the drive train. It transforms the motor’s spinning shaft into a pulling pumping force. The impeller ring acts as an extension of the impeller’s tip creates a safety barrier between the diffuser and the impeller.
How to Drain and Store a Pool Pump
If you don’t need to disassemble your pump, there are proper ways to drain and store your pump for the winter season.
- Draining: Carefully remove the strainer lid and drain plugs and turn on the pool pump briefly to get rid of all the water in the impeller. Don’t leave it turned on for long as this may burn the seals. After that, blow out the plumbing lines and replace the strainer cover and plugs.
- Storing: When storing your pump and other pool cleaning equipment, find a cool and dry place in your storage area. An airtight storage bin is a good option. Moreover, store it on a low shelf to limit the risk of falling.
With proper draining and storage, you can be sure that your pump will maintain its efficiency for the next swimming season.
