Jay installed the water system in my house,after that what a big change we felt the water we were using before. Drinking water has no more smell , no more hard water stains in bath tub, sinks , I have so many water fountains in my house all of them were blocked with the hard water stains and i had to buy them all . After Jay installed water softner all the problems are gone. We are really satisfied and i would like to suggest all my friends and family to instell too.
