I had a shower leak (dripping from the showerhead) got a plumber to change 2 of the internal cartridges as in the pictures below. Still leaks. It’s about a 10 year old Sterling fixture. The back is a pressure balancing valve with 2 screw stops.
The cartridges were expensive, that alone was $100 + labor ended up spending a lot of money, I’m not sure if they were ever really installed properly or if the cartridges were exact match because they were rebranded as “kohler”. Either way:
1. What are my options now? buy a new fixture and attach to existing pressure balance valve (is that possible?) — if so, do i need to cut tile??
OR
2. Change out both fixture and pressure balancing valve and redo tile?
Thanks for reading, appreciate any advice. Thank you.
