I bought 3 Delta 75055RB sopa lotion dispensers. After some time of usage (around 3 months), 2 of the dispensers stop working and cannot dispense soap lotion, no matter how hard or how many times they are pressed. What could be the cause? Do I need to replace any accessories, or do I need to buy a whole new set?
The Delta 75055RB is said to be with a lifetime warranty. Can I get it repaired under this warranty?
