Water on Patio or Pool Deck Instructions (Medium Capacity)

Step 3 of 3: Water on Patio or Pool Deck (Medium): Installation Instructions

Prior to installation, have your local utility companies locate and mark the location of existing utilities.

Layout your drainage system and mark the location of trenches and individual parts to be installed with marking paint before digging. Carefully remove grass or plants that are located where the trench will be dug so they can be replanted after installation. Trenches should be dug such that they slope a minimum of 1% away from your house. Place all excavated dirt on a tarp so that it can be used later to backfill.

To speed up installation, a trenching machine can be used to dig all trenches, especially in areas with particularly hard soil. NDS drainage products have been designed to be installed in any soil type. Due to the variety of pipe types and sizes, double check that all pipe connection points are the correct size. Please follow all installation directions included with the individual parts of your drainage system. To create watertight connections between products, apply a bead of waterproof silicone or glue to both parts and connect.

This system requires that the elevation of the Pop-Up Emitter be lower than the elevation of where stormwater enters the drainage system or the system will not drain.

- Dig trench for drain pipe, Micro Channel Drain, and Flo-Well.
- Dry fit (no glue) the entire drainage system from the Micro Channel Drain to the pop-up emitter.
- The Flo-Well should be installed at least 10’ away from any existing structure.
- Measure and cut all pipe to necessary lengths.
- After completing each step, glue parts together.
TIP: If installing the drain in an existing concrete area, a wet concrete saw will be required to cut the concrete prior to installation.
- Compact the soil where the Micro Channel Drain will be installed to prevent settling.
- The Micro Channel Drain should be installed a minimum of 1/8” below the finished grade of the surrounding surface.
- Connect the required number of Micro Channel Sections together using Micro Channel Drain Couplers.
- Place Micro Channel Drain End Caps at the end of the runs as needed.
- Install the Micro Channel Drain Bottom Outlet where the channel will be drained and connect the 1-1/2” schedule 40 elbow.
- If you require the drain pipe to be lower, connect a 1-1/2” schedule 40 coupler to the bottom drain outlet.
- Glue and connect elbows as needed.
- Continue drain pipe in the direction of where the Flo-Well will be installed.
- Run drain pipe from the Micro Channel Drain to the Flo-Well.
- Knock out the appropriate holes in the side panels of the Flo-Well where the drain pipe will be installed.
- Assemble the Flo-Well using the interlocking side panels.
- Slide the drain pipe through the holes in the Flo-Well side panels.
TIP: Lay the Flo-Well panels on bricks or other hard surfaces and use a hammer to knock out the holes in the side panels.
- Knock out the center hole of the Flo-Well lid.
- Place the lid on the Flo-Well side panels then place the Flo-Well Surface Inlet onto the Flo-Well lid.
- Connect the drain pipe exiting the Flo-Well to an elbow with a weep hole. The elbow should be installed with the weep hole on the horizontal side of the elbow.
- Slide the Pop-up Emitter onto the elbow. An additional length of pipe can be used to bring Pop-up emitter to the surface.
- The Pop-Up Emitter fits on the “bell” or “hub” end of the pipe or a pipe coupler.
TIP: To avoid damaging your Pop-Up Emitter with your lawn mower, raise the cutting level of the blades or avoid passing the mower over the Pop-Up Emitter.
- Cover the Micro Channel Drain grate with tape and cement or grout the channel in place.
- Remove tape after concrete or grout is dry.
- Back fill trenches and replace any grass or plants that were removed.
TIP: DO NOT BACKFILL WITH SOIL WITH HIGH CLAY CONTENT.
Water must be able to easily pass through the backfilled soil.
