i just bought a new cartridge for my tub, delta 1300/1400 series. I took the old one out & replaced it with the new one only thing is when the new one is placed water doesn’t come out of it at all. I took it out put the old one back in just to be sure boing was wrong with my line & the old one worked. Please help ! Tub has been leaking for months and I don’t know what to do!
