Downspout Drainage

Downspout piping in the St. Louis Metropolitan area is extremely important. We’ve all experienced the wild swings in weather that can happen hourly… one minute you’re sitting by your pool relaxing and the next minute you’re vacuuming water from your flooded basement.

In the Midwest, unlike other parts of the country, having your rainwater downspouts connected to underground PVC piping is a critical, must-have feature. Similar to a solid roof or functioning gutters, gutter downspout drainage solutions must be given the attention required to ensure you have a long-term, always functioning solution. This helps protect your home from flooding, potential damage to your foundation, erosion issues, landscaping damage, and much more.

Read below to learn about the common issues we experience with traditional downspout piping on a daily basis, and why they occur. As you read, you will discover our downspout drainage options and what our company can do to provide you with a permanent solution for controlling your roof water.

Causes of Downspout Water Issues

Downspout Water Runoff

Standard downspout drain pipes run onto a splash block and basically dump water down the homes foundation. This leads to water running down the foundation to the footing which commonly jeopardizes the integrity of the foundation over time causing potential settling, basement flooding, etc.

Corrugated Piping

The black corrugated piping and pop up gutter drains that people buy from box stores is a major problem. It clogs, collapses, and fails over a short time after installation. It’s a bandaid fix, not a long-term solution.

Improper Sloping

Downspout piping has to be installed at the proper slope. If not, water will not discharge efficiently and will likely run backwards and run down the homes foundation.

Under Sized Pipes

Many property owners and contractors under estimate the size of the pipes needed to pipe water away from a home or building, especially the size requirements to handle a flash flood rain event. We commonly see a home that has 3 – 5 downspouts running in 4″ corrugated piping that’s all TEE’d together, and they wonder why it’s not working…

Pipe Maintenance

Just like gutters, underground downspout drains accumulate leaves and debris over time. Downspout piping must be flushed a couple times a year to make sure they’re clean when you need them most.

Construction Without Focus On Drainage

It’s common that property owners have remodeling and construction upgrades done on their property. More common than not, downspout piping and drainage is not a focus until water damage occurs, long after the construction project is completed.

How We Solve Downspout Piping Issues

PVC Underground Piping

Schedule 35 Sewer & Drain Pipe is the best PVC gutter pipe for downspout piping projects. It’s smooth walled on the inside, typically self cleans, holds up to freeze thaw, and is overall the best choice for drainage.

Correct Pipe Sizes

We analyze the roofs square footage and watershed during worst case scenario rain events. We then size downspout drainage system pipes accordingly.

Cleanout Connections

Cleanout connections are standard on all of our downspout connections. This give our clients access to the pipes and protects their investment for decades.

Proper Levels

We use a transit to shoot the grades to make sure we have proper slopes on all of our piping installations. Our work is guaranteed, so we can guarantee our clients it’ll be done right the first time.

Pipe Discharge

Our standard downspout piping configurations discharge at the correct location to minimize erosion and maximize efficiency all while self cleaning.

Compaction & Restoration

When our downspout drainage ideas are installed and complete, pipe runs are compacted. Additionally, any disturbed area are restored to pre-project condition (often times better).

Cleanout Connections

On all of the downspouts we pipe, we install PVC downspout adapters with cleanout connections. This provides our clients the peace of mind that their storm water system can easily be accessed to perform downspout cleaning and check functionality. If you install PVC gutter downspout drain piping without cleanout connections, your only option to access the piping is to cut out a section of piping or to dismantle the downspout from the connection. Cleanouts are an absolute must on downspout extension drainage systems.

PVC Downspout Piping

We install the best storm drain piping for our clients gutter downspout drainage projects, installed with the best installation practices.

Drain lines are all heavy duty schedule 35 sewer and drain pipe with glued connections. All turns and inflow connections are done utilizing 22’s, 45’s and WYE connectors.

Intricate Piping Installation

The skills of our downspout piping crews are unmatched. We can install pipes through the tightest of areas, many times several pipes in one trench. Going around utilities, through 100-year-old delicate tree roots, etc. is not a problem.

No obstacle is a “project stopper” for our crews.

Discharge Efficiency

Daylight the end of the pipes.

Years ago we used pop up emitters at the end of our discharge lines, and yes they look pretty (for drainage) and are hidden in the grass.

Problem: pop up drain emitters restrict water flow and also trap leaves and other debris in the pop-up elbow.

For the past 15+ years we have simply been daylighting the pipe at the end to allow water to free flow out of the end along with any debris in the pipe (this is absolutely the most efficient way for a piping system to operate).

Decorative Discharge

We have decorative options to make the discharge point(s) look like a landscaping feature and we can even camouflage the exit pipes with boulders so they are not visible, but still maintain full water flow.
