How to install Water Softener Rheem DIY

DIY. I'm not a professional plumber but I installed my Water Softener Reheem 42K for 6 people which works perfectly. The house builder has already instalation plumbed. I tested water haednies before installation it was hard water between 125-250ppm and after installing whole house filtration and water softener it was soft water around 25ppm. I will be glad if this video helps someone. thank you
