We recently bought a house that has a UV water filtration system and a water softener system. We are new to this system and I have done a lot of research and am unable to find a manual or how to for caring for the water softener system. I'm pretty convinced it needs salt cubes added. I did speak to a company that recently replaced a drain line but couldn't tell me the model (?) or anything other than the water should be anywhere from 8-10 inches deep. From what I can see that's about right, but there is very little salt in the tank. I did break up the bridge that had formed but I am leary of adding salt because I know basically nothing. She did tell me that there is a filtraiton system than could help with the egg smell, only $1900! Hopefully someone on this forum can help me out. So far it has been the most informative site I've been too! Thank you!
