It is possible that your water utility has repaired a lot of water leaks, and has uprated the mains pressure in your area. Try reducing the rising main valve feeding thro' the combi to your hot taps;- just strangle it a little. My own home town has been completely re-piped, due to foul deposits lining the pipes, + they installed header-tanks inside 2 tall hills to enhance the static pressure, should a pump fail.
