How Long Do Sump Pumps Last?

How long do sump pumps last? This is a question that many homeowners ask themselves. In this article, we will answer your question and give tips on extending the life of the sump pump.

Sump pumps are an important part of the hot tub system. These devices take water collected in the sump basin and send it to a place where it can be filtered, processed, or treated before being put back into the hot tub. 

But how long should you expect your hot tub sump pump to last? This article will go over the common signs that tell you it is time to replace your device.

How long should my hot tub sump pump last?

The first question when it comes to when do you need a new hot tub sump pump in your home is how old it is. 

No matter what brand of sump pump you have, an annual inspection should be conducted by a certified technician who has experience with your specific model to make sure that everything works as it should. With this in mind, if you are unsure about when your hot tub sump pump was installed or replaced – do not hesitate to ask your contractor or plumber.

If the sump pump is older than ten years, it may be time for you to consider replacing it with a new one. The age of the hot tub sump pump is not the only thing that matters though – also pay attention to whether there have been any signs of malfunctioning in the past. 

Signs you need to replace your hot tub sump pump

There are a few things you should take into account when deciding whether or not your sump pump needs replacement. 

The sump pump is running constantly

One of the most important signs that you need to replace your sump pump is if it’s running constantly. If it’s staying on longer than usual, this could be a sign that there is too much water in the hot tub, and your old system can’t keep up with removing all of the excesses from inside.

The sump pump is making loud noises

If the sump pump is making loud noises, it is a red flag that you should probably replace the sump pump soon. The sound of water rushing through the pipes will get louder and more frequent if there is too much pressure on your current system or if debris has built up in the impeller causing it to seize up.

The sump pump is clogging

The hot tub sump pump is clogging with dirt and particles through time. These things may damage the pump, which is why it should be cleaned frequently. The sump pump itself has a battery that works for several years but if there are some malfunctions in its work you have to call an expert immediately because these problems can cause great damages to your hot tub.

The sump pump is cycling erratically

If you notice that your sump pump is cycling erratically, the first thing to check is the switches. The switch should be clean and dry — if not, then it may need to be replaced or cleaned. If this does not solve the problem of an erratic cycle, the next step would be checking if there is a blockage in the discharge line. If there is no blockage, then it may be time to replace the sump pump itself.


A sump pump is a useful tool in the hot tub, but it is also one that you must take care of regularly. Although sump pumps are generally durable and can last for many years, they do come with an expiration date. 

A sump pump can last anywhere from five to ten years, depending on how often the hot tub is used and what type of environment that it lives in.

Signs you need to replace your hot tub sump pump include:

  • When the pump does not turn on automatically when it is supposed to;
  • When there are water leaks in any part of the hot tub system;
  • If you hear loud grinding sounds coming from your sump pump. 

If you notice these signs, then it may be time to replace the device.


🤔 What is the best type of sump pump?

There are two types of pumps – submersible and external. Both have their benefits depending on your situation. An external system can move more water but requires electricity whereas an internal system does not need any electricity.

🔍 How long do sump pumps last?

The lifespan of a sump pump depends on the climate. In general, they will last between five and ten years.

👀 What are the signs that it is time to replace my sump pump?

You need to replace your sump pump if:

– It’s making noises;
– The float switch sticks or frequently gets stuck in one position;
– It isn’t draining water properly.

💧 Do I have to drain the hot tub to replace the pump?

You should not drain the hot tub to replace a sump pump. However, if you have an external system then it will be necessary because water is unable to flow into that type of system.
