Its lifespan matches that of the swimming pool. This is due to the high-tech, engineered, flexible tubing which is impervious to chemicals and mineral build-up. InDekSolar© tubing is freeze resistant and elastic and flexible enough to withstand extreme pressure inside the concrete. Since 1982, our first InDekSolar© system has been providing trouble-free service to its owners. No repairs have been made to date. We guarantee the InDekSolar© Tubing, inside the concrete deck for your solar Pool Heating System, with a full 20-year warranty.
