When we turn on hot water tap first thing in morning, or shower, water
flows for about minute, stops or slows right down, then after few
minutes begins to flow again, but often need to turn tap/shower full on
before get hot water, then comes out at a rush. When happens with
shower the shower cable and head violently shake as water gushes out
where moments before there was a trickle. Now we find the shower is
constantly dripping. What need do...are these problems connected? Hot
water and heating through Worcester Bosch combie boiler.
