Buying Guide for the Best Sump Pump for Crawl Space

When choosing a sump pump for your crawl space, there are several factors you need to keep in mind. Here are some of the most important things to look for:

1. Pump Type

Sump pumps come in two types: submersible and pedestal. Both types of pumps have their advantages and disadvantages. Submersible pumps are more durable and can last longer, but they can be more difficult to install. On the other hand, pedestal pumps are easier to install but may not be long-lasting.

2. Horsepower

The horsepower (HP) is a measure of the pump’s power. The higher the horsepower, the more powerful the pump will be. However, a more powerful pump will also be more expensive to purchase and operate.

3. Gallons per Minute (GPM)

The GPM measures how much water the pump can move in a minute. A higher GPM means that the pump can carry more water, which is vital if you have a lot of water to remove.

4. Lift Capacity

The lift capacity measures how high the pump can lift the water. A higher lift capacity means that the pump can remove water from deeper depths.

5. Durability

You want to make sure that your sump pump is durable enough to handle heavy-duty jobs. When shopping for a pump, look for pumps made from quality materials, like stainless steel or cast iron.

By considering these key factors when choosing the best sump pump for the crawl space, you can make an informed decision and find the right pump for your needs. Then, with the right sump pump in place, you can rest easy, knowing that your crawl space is safe from water damage.

How To Install a Sump Pump in Your Crawl Space

Installing a sump pump in your crawl space is a relatively easy process. Here are the steps you need to follow:

Find the right location

Choose the right location for your sump pump. The location should be close to an outlet and far enough away from any walls or obstacles.

Dig the Pit

Once you have chosen your sump pump’s location, dig a deep enough hole to fit the pump and leaving room for gravel at the bottom.

Install the Basin

The basin of your sump pump should easily fit into the hole. If you are having trouble doing it, try adjusting the depth of the hole or using a different size basin.

Install your Pump and Connections

Once your sump pump is in place, the final step is connecting it to the power outlet and any hoses that will connect to it.

Install Drainage Lines

If you do not have drainage lines already in your crawl space, now is the time to install them. These can be simple plastic tubes or PVC piping that will direct water from your sump pump into a safe location outside of your home.

Test the Pump

Once your sump pump is installed, test it to ensure that it is working properly. You should test it at least once a month to ensure reliable use.
