Installing a sump pump and waterproofing system is the least disruptive and most effective way to keep a basement dry – and keep it dry all the time!

The following are steps our basement waterproofing technicians take when installing a sump pump system in your home. At Complete Basement Systems, our certified basement waterproofers can install a complete sump pump system in just one visit to your home!

Placing the Sump Pump Liner

First, a sump pump pit is excavated for the liner and pump to be placed in. This protects your sump pump from the mud and debris around the pump pit.

It’s important that the sump pit is large enough, but not too large. When placed in a small pit, a sump pump can pump water out faster than it can fill the liner, causing them to turn on and off quickly and burn out sooner. Sump pits that are too large tend to go too deeply into the ground, pumping out water far below your home, causing unnecessary work and electricity usage.

Sump pumps are most effective at removing water from under your basement floor when located in the lowest spot of the floor. Your certified waterproofing specialist will determine where that spot is by using a laser level. If the sump cannot be located in the low spot, a PVC feed line should be run through the floor from the low spot to the sump pump location.

Installing a Perimeter Drain System

When installing a reliable sump pump system, it’s a good idea to install a perimeter French drain system, like BasementGutter™.

First, the floor around the edge of the basement is jack hammered, and a layer of clean stone is set down. A perimeter drain is installed on top of the stone, and is back-filled with more clean stone.

The purpose of this drain is to collect water from the basement wall-floor joint, the basement walls and from under the basement floor, and direct it to the installed sump pump.

Our patented BasementGutter™ Basement Drainage System includes a wall flange that extends slightly up the basement wall to collect water that may leak from the walls. If you have one of our basement wall products installed, the wall covering will be tucked behind the flange to direct moisture from the walls into your drain.

If your home has concrete block walls, weep holes will be drilled in the blocks at the very bottom to relieve the water and the pressure from the walls.

The Sump Pump Installation

A special outlet connects the perimeter drain to the sump pump system and clean gravel is back-filled around the sump pump liner.

This gravel helps to keep your sump pump system as clean as possible, discouraging silt and sediment from entering the liner.

An airtight sump pump lid including rubber grommets around all pipes and wires, keeps odors and humidity from rising out of the sump pit, while also preventing items and debris from falling in from the basement floor. Having an airtight, secure lid on your liner is also excellent in preventing animals and children from attempting to play in the water!

If you have a secondary pump installed in the pit, an additional discharge line will be installed. This prevents the pipes from being overwhelmed and also ensures the pumps won’t pump back and forth between each other. Discharge lines should NEVER be tied together on the inside of your home!

Restore the Floor

To complete the sump pump installation, the floor is restored flush for a clean, attractive look.

The system we use does not leave a gap around the perimeter of the basement floor which can collect dust, debris, and other items that can clog your waterproofing system. This helps ensure better drainage and a more reliable system. Our system also provides a clean, neat, and professional basement repair.

Outside, an anti-freeze device called FreezeGuard™ is usually installed. The discharge line is buried underground, while the installer is careful to remove sections of the lawn in whole pieces before making the trench for the pipe. This helps to ensure the least disruption to your landscaping throughout the installation. A special outlet is installed flush with the ground and is safe for lawn mower or lawn tractor traffic.

The Cleanup & Finishing Touches

Our sump pump installation crew takes extra care to leave your basement clean, neat, and clear of debris for you at the end of the installation.

Dust is cleaned from the basement floor and the discharge line outside is inspected to be sure that the water is being discharged to an appropriate location.

We remove all debris we create, and most times customers comment their basement is cleaner than before we started!

To allow for future testing or inspection, Complete Basement Systems will install several “ports” in the perimeter drain, where a hose or dehumidifier drainage line can be inserted. During annual checkups and sump pump maintenance, this helps us with testing and inspection.



Some people wonder whether sump pumps are actually necessary for their homes. After all, do you need a sump pump if you don’t live in an area prone to flooding? As a matter of fact, there are many reasons that every home should have a sump pump. 

  • Basement Waterproofing Overall

First off, it’s crucial that you pay attention to your basement waterproofing processes as a whole. Basement waterproofing is a complicated process that requires paying attention to a number of different elements of your basement. You need to make sure that you have a sump pump as part of that basement waterproofing process.

There are, of course, other elements of basement waterproofing. Whether you need to add a basement dehumidifier, an interior drain, or something else, a sump pump won’t be where your basement waterproofing stops. However, it can be a great starting point if you don’t have any basement waterproofing systems in place.

  • Interior and Unexpected Floods

You never know when you might have an interior flood in your home. Interior floods can be a huge problem because they’re essentially unavoidable. Having a pipe burst is something you can try to avoid as much as possible, but you’ll never be able to completely ensure that it never happens. This can easily lead to basement flooding.

Plus, even if you don’t live in an area that’s technically prone to flooding, there’s no telling what might happen in the future. There are all sorts of reasons that an area that’s never had flooding problems in the past is suddenly overcome by one. When you have a sump pump, you’re prepared even if something happens unexpectedly.

The concept of different sump pump systems can be confusing to someone who doesn’t know how sump pumps work. What are the different sump pump systems you might be able to get through Complete Basement Systems?

  • Basement Sump Pump Systems

For the most reliable experience, you’re going to want to opt for the SafeDri Triple Sump Pump System. You’ll typically be using the main sump pump, which can pump 2,220 gallons of water every hour out of the basement. It also has a secondary pump that can discharge an additional 3,900 gallons of water per hour and a backup battery sump pump, just in case.

If you don’t think you’ll need that much power but you still want a reliable pump solution, you may want to choose the SafeDri ProX Premier Sump Pump System. It still utilizes the main sump pump but doesn’t have a secondary pump. Plus, you can also add a rechargeable battery-powered backup that can pump up to 11,500 gallons on one charge.

  • Crawl Space Sump Pump Systems

What if you’re looking to keep your crawl space clean rather than your basement? This is when you can turn to the SafeDri Pro Crawl Space Sump Pump System. This system includes the primary sump pump and an optional battery backup sump pump. The difference is that it will fit with a CrawlSeal liner, making it the perfect option for your crawl space.

When you’re choosing a sump pump for a crawl space, you’ll also need to think about crawl space encapsulation. The CrawlSeal liner is an element of crawl space encapsulation, which is its own complicated process. If you have a crawl space, talk to an expert before you install a sump pump to learn about that entire system.

Although the sump pump itself should be something you think about when it comes to installing your sump pump system, it’s not the only part of your sump pump system. Make sure you’re thinking about these other elements of your sump pump system as well.

  • Backup Sump Pump with Alarm

A backup sump pump can be incredibly helpful for your sump pump needs. That’s because you always want to be prepared for the possibility that your power will go out while your sump pump is working. If it does, you’re going to have to deal with water constantly building up in your basement unless you have a battery-powered backup that can help.

A sump pump alarm is also an important element of your sump pump because it helps you know when something might be wrong. Most of the time, a sump pump alarm will turn on if the water in your basement or crawl space reaches above a specific level. That can alert you to the fact that the sump pump might not be pumping quickly enough for some reason.

  • Other Basement Waterproofing Products

A sump pump should not be your only basement waterproofing method. Although it can be an effective method of getting water out of the basement, you also want to make sure you’re making it as difficult as possible for water to get into the basement in the first place. That means relying on other basement waterproofing products as your line of first defense.

Basement waterproofing is complicated. As you’ve already seen, a proper basement waterproofing system should need more than just a sump pump. The important thing to remember is that every element of your basement waterproofing system needs to be of the highest quality possible if you want it to be effective.

The process of installing a sump pump in your basement is often complicated and can be confusing. That’s exactly why it’s so important to consider the different ways that you might be able to install a sump pump in your basement. 

  • DIY Option

Installing a sump pump in your basement isn’t usually something you can do yourself. It’s true that there are a variety of DIY options around your home, and for the most part, DIY options can be a great way to save some money and time. The thing is, DIY fixes aren’t perfect for every area of the home, and the basement is a good place to stay mostly hands-off.

In the case of a sump pump, you’re going to be dealing with technical and expert-level elements that make this difficult to maintain. Installing a basement sump pump requires textbook knowledge and hands-on experience. Allow an expert to do it from the beginning so you don’t have to spend extra money in the future.

  • Installation From an Expert

This is exactly why you instead need to trust an expert. An expert will help you install your sump pump properly. Plus, some locations may offer warranties on their work, which means if you ever have an issue with your basement or crawl space sump pump, you can come back to the company that installed it and ask for help.

Upgrading Your Basement

Once your basement is protected from water seepage, it’s a great idea to take advantage of the cleaner, drier, more attractive area as storage or living space.

If you don’t already have one installed, be sure to ask about our battery backup sump pumps, as well as our basement wall coverings, ENERGY STAR® rated dehumidifier, waterproof basement flooring, and other basement products that can add energy efficiency, beauty, and comfort to your home.

Complete Basement Systems also provides crawl space sealing and encapsulation!
