Hi, Have a Baxi Mega Flow and had a plumber round to change the top up immersion. Since then we have plenty of hot water and always good pressure which is great but the cold water is now really inconsistent.
In the morning when I turn the shower on the mixer taps in the bath start at a really good rate but then the whole flow drops off to a trickle before coming back again to a reasonable flow...or at least good enough to shower.
The cold water taps in the bathroom and kitchen vary between a reasonable but low pressure flow to very low pressure barely over a trickle..whilst the hot water is always strong. Any advice much appreciated.
