The intake line can be safely installed directly from the intake filter in the tank to the RAINMASTER Eco control unit with the HORIZON 1/2" intake hose, made from high quality EPDM rubber. This means no additional joins or pipe sealing is necessary, which in turn limits the chance of intake pressure problems at the control unit side. The HORIZON intake hose is resistant to the impact of harsh weather conditions and contamination, including degradation by UV light and ozone. It is highly flexible, twist-free, bend-proof and pressure resistant due to its reinforced inner core. It is suitable for use with INTEWA MD-100 and MD-150 wall bushes.
