Here is what you need to know about buying a new sump pump. This is a quick guide, that should provide you with all the information needed to make an educated decision.
Always replace the check valve when replacing the sump pump. An old check valve can cause a new pump to wear out very quickly. There are 3 main factors to consider.
Material- This is BY FAR the most important factor to consider. This determines a sump pumps longevity, cooling ability, and durability. Thermo-plastic is the worst in just about every way. Cast iron is the most durable, but has a tendency to overheat and can rust out after about 10 years or so. We think baffled aluminum is by far the best. The baffles, or cooling fins, provide the pump with extra durability and increase its surface area and ability to cool. Unlike cast iron, aluminum will never rust. If you don’t want to go with a baffled aluminum sump pump, cast iron is a great choice!
Warranty- Most companies either provide a 1 year or 3 year warranty. It worries me when a company will only warranty their product for 1 year, because a quality sump pump should last 10+ years.
Horsepower- In almost every situation a 1/3 horsepower sump pump should be more than enough. In some cases a pump with more horsepower or improved cooling is required.
It might be tempting to buy a cheap plastic pump. However, in the long run it’s usually cheaper to buy a quality sump pump, especially when you factor in the cost of your time.
Brand & Price- There are tons of great brands out there! As long as you buy a reputable brand from a reputable supplier, you really do not have to worry about overpaying.
