Poor bathroom performance can come from the incoming supply, the boiler or cylinder arrangement, restrictive pipework, partially closed valves, blocked shower components or the type of shower fitted. The first step is to determine whether the problem affects every outlet or only one fixture.
If all cold taps are weak, the incoming supply may be relevant. If cold flow is good but hot flow is poor, the hot-water system needs attention. On a combi system, available mains flow strongly affects shower and bath performance.
Doherty works on both boilers and bathroom installations in Glasgow, which is useful when poor shower performance crosses the boundary between bathroom fittings and the hot-water system. The cause should be identified before buying a new shower or larger boiler.
