500'- 5/8” Inch ID x .820 OD Mr. Drip Bulk Lead Free Bulk Soaker Hose offers the perfect delivery of water to plants. Made from recycled materials, 70% from recycled rubber and 30% recycled polyethylene products that are re-pelletized for use in the process. Bulk Soaker Hose means there are NO fittings on the hose. In turn, you can cut to desired lengths to create your own custom system. 5/8” Soaker Hose can be run in lengths of up to 250', but not to exceed 500' from one water supply. GPH is "approx." 224 gallons per hour, per 100' at 25 psi, depending on inlet pressure, water hardness. Shorter lengths will have an increase in GPH. Use this size if your rows need to be between 150' - 250'. We suggest using standard .820 compression fittings found here on Amazon. Compression fittings fit over the top of the soaker hose allowing more water flow than fittings that you insert into the hose. Hose should be used on flat surfaces not exceeding a 2' rise over 100'. A quality 25 psi regulator is a MUST since soaker hose is designed to work at low pressure. Always use a 200 mesh screen filter to help prevent clogging. Use a soaker hose calcium filter in areas with hard water. Tip: Always try and create a loop in your system for even flow for soaker hoses, and drip irrigation systems.
