How To Replace A Pool Pump Water Seal? [Solved!]

Spread the love

There are several reasons why your pool pump might need to be replaced. The most common one is corrosion from the water striking the motor directly. A weaker motor could be caused by low water pressure, which can make the water appear choppy or turbulent.

If you are reading this, you are probably wondering how to properly replace a pool pump water seal. The process is actually quite easy, but since there are several parts that might be implicated, you need to take things one at a time. First, you will need to shut the pool down so that you can do some major cleaning. Bear in mind that if there is any chance of contamination, you will have to thoroughly clean all the surfaces and tools involved before use.

How To Replace The Motor And Bearings

Since the motor is the heart of the pump, it is the first thing to check. First, determine if the motor is a split-style or a whole-style motor. A whole-style motor has a solid shaft whereas a split-style has a hollow shaft. A whole-style motor is more reliable and will not require as frequent replacements as a split-style one.

Next, take a look at the bearings. You have two choices here: ball or roller. A ball bearing can be found in most household appliances and industrial machinery. It is made of metal, ceramic, or a combination of both. The downside to a ball bearing is that it can seize up after a while, causing major headaches and stress for anyone trying to operate the machinery.

A roller bearing is similar to a ball bearing but with a few differences. These are mostly cosmetic and do not affect the operation in any way. A roller bearing is also much quieter and smoother than a ball bearing. Since most modern pumps use roller bearings, they are much more acceptable for use in residential areas.

The best and most reliable type of bearing for a pool pump is a sealed bearing. This type of bearing is quite robust and will not require nearly as frequent replacements as most other bearings. Moreover, it is far quieter and smoother than any of its counterparts. Plus, it has a longer lifespan.

Replace The O-Ring

The next step is to replace the o-ring that goes around the shaft sealing it. These rings are made of rubber or other resilient materials and come in various sizes and shapes. The correct sized o-ring for your pump will be either.003 or.004 inch in diameter. If you do not know which one is appropriate, test it by installing the pump and checking if there is any fluid leak. If there is, then you have the smaller one, otherwise, you need the larger one.

Clean The Inside

After you have replaced the motor and the bearings, it is time to clean the entire pump. You must ensure that there is no oil or other foreign substances left inside. Use a cleaning product that is specifically made for pool pumps and follow the instructions carefully.

Additionally, it is a good idea to dry the inside of the pump with a towel before using it again. This will help prevent any future buildup of algae or other water-borne pathogens inside the pump.

Install The New Pump

After you have cleaned and dried the inside of the pump, you can finally replace it. Make sure that you install the new pump with the proper orientation or else the whole process might be in vain.

If you have done everything correctly so far, the process of replacing the pool pump water seal will be easy. All you need to do is remove the existing pump and then replace it with the new one. To prevent any accidents, take the time to read the instructions thoroughly and make sure that you do everything safely and correctly. You should also get professional help if you are not sure what parts to use or how to put them together correctly.

Use Sunscreen And Sunglasses

In case you are wondering, yes, it is recommended that you wear sunscreen and protective glasses while working around the pool. Just make sure that you remove them before going inside the pool or else you might get too sunburnt or otherwise injured. The rule of thumb is: wear sunscreen first, then the glasses, and finally the swimming suit or bikini.
