Hi, I have had an ongoing issue with a shower/bath mixer that appears to be getting worse.
The system runs of a combi boiler.
The temperatures of the bath/shower water is lukewarm at best, measured earlier as around 32 deg max and this fluctuates. The thermostatic cartridge was recently replaced due to being clogged with scale (very hard water area - the whole water system was only installed ~2 years earlier) and is configured to max heat.
The shower is concealed but I have removed the front plate and exposed the outlets. Flow rate of cold water coming out is much higher that warm (I would guess about 3-4 times as much).
I don't have an issue with other taps in the house - hot water is too hot to touch but clearly the flow rate is much lower.
I am wondering what the likely cause is with my limited plumbing experience. As stated the cartridge was recently replaced and there is a big imbalance in the flows, but shouldn't the cartridge "balance" the amount it takes in?
Is it normal for the hot water flow to be that much lower than cold water flow? Would the issue be caused by a possible blockage in the boiler (considering the hardness of the water) or could the supply pipes be blocked?
Grateful for any advice.
