3" x 339' RioFlex Pressure Vinyl Mainline Hose by SAB

SAB started the RioFlex Project in 2015, with the aim of creating a manifold pipe, designed for drip irrigation systems, which had to be resistant, easy to use and completely recyclable.

UV Protection makes it tough and malleable!  See the link for brochure and video above.

DRIP DESIGN GUIDE by Jon at Berry Hill Irrigation

• RioFlex is fully made of polyethylene, a well-known material, renowned for its virtues and on which SAB has already a long experience.
• We have used four different types of PE on RioFlex, to obtain a pipe with features apparently in contrast among themselves.
•  
• Rioflex has been conceived to be strong and tough, yet light and flexible. Polyethylene has a low roughness rate, to reduce pressure loss and has a very low sensitivity to thermal expansion.
• RioFlex can be supplied with pre-installed connectors at a required spacing, to make the installation and the dismantling at the end of the irrigation season much faster.
•  
• Using RioFlex is really easy. Instructions and recommendations for the installation are supplied with the pipe.
• It is going to pay you back with a long-lasting life, after which it can be recycled along with the drip tape.

Step 1:  Add up your total row feet of drip tape in each field. Figure GPM (gallons per minute) in each field by total feet x flow rate of tape.

Step 2:  Pick  Sub-main Pipe size by your flow going through.  1 1/2” up to 17 gpm 2” up to 35 gpm 3” up to 75 gpm  4” up to 160 gpm.  We usually use flattube (Oval Hose) 

Step 3:  Choose a manifold that fits your fields layout and carries enough water for that field.  Manifold B is most desired because of even pressure over submain.

Step 4:  Chose Main Line that will carry gpm for each field that you would like to water at one time.  1 1/2” 30 gpm,  2” 50 gpm 3” 110 gpm 4” 190 gpm.  We usually use Layflat.

Step 5: Chose Media Filters that will allow enough flow for all fields that you would like to water at one time and handle pressure.             Fiberglass Filters are the most popular and handle up to 50 psi. 

Step 6: Choose a Fertilizer injector. For pond systems, we recommend a Mazzei Injector.  For Homeowners and Gardens (large or small), the EZ Flo is an excellent choice.

Step 7: Pick a pump that will deliver enough water  and leave you with enough pressure to make the injector, filters and loss in the pipes.   Please call for assistance. 

Step 8:  Decide on your fittings you would like to use: 400B fitting or 420-BV-06-LS that has valve on each row.   Add up total number of rows and order one fitting for each and a punch.

Step 9:  Order fittings to go around obstructions and to mend pipe as needed.  Tape couplings, goof plugs, clamps, Insert fittings

Step 10:  Call us with your order or come by and pick up.
