4040 Ro System With 1200l Water Tank and Shut Off Valve.. Auto shut-off valve converter with 220V, you can plug in in a normal socket. The system hasn't been used since March. I did change all the filters and resin in January 2023. The membrane is very good, before the resin the water come at 008, with the doubble vessel I normally change the resin every 6 to 8 month.
Keep in mind that the system filled the tank every day monday to friday, suppling water to two vans, one with a 650l tank and one with a 350l tank. Any question please contact me.
