Run Gutter Drain Underground

Screw a drain cover over the end of the tubing as it approaches daylight to keep critters out.

Run gutter drain underground.

My plan was to use 4 pvc pipe with fittings to make a y shape away from the house. I settled on this design because i wanted as few angles as possible so that any speed the flowing water picked up would not be slowed down by making a 90 degree corner. Use this downspout extension to divert water away from the foundation or connect to drainage pipe and catch basin to control drainage. This greater volume of water creates a huge load on the sump pump which will run almost continuously in heavy rains shortening its life and increasing the risk of failure.

The process to install underground gutter drainage to move water away from the foundation of a home also known as a french drain. Water flows downhill so you have to have some amount of slope so the water will run somewhere. It s standard to have them run into underground drainage pipes that carry the water away from the house. Debris flowing down the downspout drain leaves from gutters can block floor drains or even the main building sewer line leading to sewage backups into the structure.

When the water from the downspout flows into the drain tile system it multiplies several times over the volume of water the drain tile was designed to handle. Blockages in the under floor drain combined with high volumes of roof runoff water entering the system send the entire roof runoff into the building basement or crawl space. This flexible downspout extension easily bends and holds its shape and can be extended from 25 55 in. A gutter s purpose is to move water from a roof to the desired location but usually this is right by the foundation of a home.

Featuring durable plastic construction this extension can be buried bent or connected to additional sections. Something that can be very damaging to the foundation of a home is exterior water. To prevent erosion make a rock bed around the end of the tube. It looks ugly and when the tube falls off the basement floor gets wet.

Where the tube passes by the downspout from the gutter we installed a y fitting and drained the roof water from the gutter system directly into the main drainage line. However if the underground piping doesn t hook up to a drainage or storm sewer system you could be increasing your chances of basement problems because the water is not getting directed away from the house. A solution is to direct the water into an underground discharge out to the lawn and eliminate the visible pipe or splash block.
