Hi guys I seem to have an uneven flow of water from one handle to the next, when I let the water flow from the right side it does not flow like a shower, it seems to flow like a running tap, the left side flows like a shower and seems fine, this is affecting my grind as each side doesnt seem to have the same pressure flow, I have backflushed both sides many times with chemicals and doesnt seem to have much effect. Any advice would be greatly appreciated.
