Why Do You Need The Best Outdoor Sump Pump?

An outdoor sump pump will be required if the soil drains poorly or the water table is near the soil surface. When it comes to small yards, dry wells are frequently ineffective because they can’t hold enough water from the runoff.

On the other hand, a dry well that sits a little farther away from the house and utilizes a sump pump would be a better option.

In either situation, dry wells alone cannot put water into the ground safely and quickly enough to make room for the next downpour. Therefore you need to buy the best outdoor sump pump.

How Does An Outdoor Sump Pump Work?

Installing an external sump pump to your drainage system is an excellent finish to your drain system. You begin by installing perimeter drain pipes, a French drain, or other yard drainage solutions. Once they are in position, you connect your drainage system to your sump pump in the backyard.

A submersible pump is buried in the soil of a sump pit and pumps water out when the water level rises. A discharge line expels water due to the pump pushing it up and out. The pump is powered by electricity and may require a backup battery in an emergency. 

The amount of water and setup will determine whether you drain it into a storm sewer or a safer portion of your yard.

How To Install The Best Outdoor Sump Pump?

Most outdoor sump pumps drain into the road or attach to the sewer line. I have put together step-by-step instructions to help install your basin and in-ground sump pump and set up the appropriate drainage lines!

1. Find the low spot

Begin by finding the low spot in the yard where groundwater is pooling. This is where you will want to install your exterior sump pump basin.

2. Find the sewer line

Next, locate the sewer line to install the check valve and discharge pipe.

3. Dig a basin pit

Dig and establish a basin; set it below the water table.

4. Run electrical connections

After you dig the pit and set the basin in position, install the electrical connection and battery backup.

5. Install the sump pump

Next, install the sump pump at the base of the basin.

6. Attach the drainage

Attach the drain lines and check the valve after the pump is positioned.

7. Test system

Once everything is in a place full of a few buckets of water, check the pump system to simulate a rainstorm and ensure everything is in working order before the next heavy rain.

These steps will help you install the best outdoor sump pump easily.

Five Ways To Prevent Outdoor Sump Pump Freezing

Your sump pump may freeze if the temperature drops below freezing. Outdoor pumps can be tricky, but frozen water may cause significant issues! It is critical to take measures to safeguard your pump for cold weather. 

Here are some suggestions for preventing permanent pump damage and drainage issues: 

1. Cover the basin

It is simple to keep your pump from freezing or being damaged by covering the basin with a sheet. Even a light sheet can make a big difference if you have a basin cover. This method is not difficult to implement. Clearing the snow and ice off every few hours might be difficult if you have a basin cover.

2. Drain standing water

In cold weather, your shallow pit’s standing water can freeze, jeopardizing your pump. Extract as much standing water as possible before winter to reduce the risk. Your pump should take care of most of the work, but you can always empty the basin or use a shop vacuum on your dry well if you’d like.

3. Bring the pump inside

If you anticipate a winter storm, move your sprinkler system’s pump into your garage to keep it safe from ice damage and water. Even if the weather is below freezing, water near the surface freezes all the time, so you don’t have to stress about draining your yard. Keep the unit indoors to protect it from ice damage and prevent water leakage into the electrical system.

4. Remove ice

Keep ice away from the pump to ensure your pump is warm. You can use a little shovel or your hands to clear ice and snow from the pump basin. Remember, if your pump gets too cold, it will not function once the snow melts!

5. Check the drains

Your pump won’t be able to push water if your drains and sewer lines are frozen shut. Pour hot water down the drains to ensure they are not frozen shut. If the pipe cracks or floods because of a frozen drain, remove the ice manually before it’s too late.

Can sump pump be installed outside?
