I just found out that water faucet I am using to fill my spa actually goes through my water softener first . I have 3 outside water faucets and the plumber told me only one is not connected to the water softener . What impact does this softened water have on my hot tub water since it has salt in it? Am I ok to use or should I drain and only fill from the faucet that is not connected. I have a pool too but we have a swg so I would think it would hurt the pool
