Hot water from bath tap only takes ages to come through

[comeonthetowen]

Hi there,

Hot water fine everywhere else, but takes several if not 5 mins or so to arrive. Once started, fine.

Tried hose from cold tap to remove potential airlock. no joy.

Any help much appreciated

thanks

5 minutes is verging on unbelievable

1) Do you have a hot water cylinder, or a combi? Is it higher or lower than the bathroom? How much?

2) How far is it from the bath tap?

3) When you run the bath tap into a bucket, and time it, how many litres per minute does it deliver?
4) Do you mean it delivers cold water before it goes hot, or do you mean nothing comes out of the tap?

Thanks

Two bed terrace house.

hot water cylinder (gledhill combination no 2 46 x 18 22/20) in airing cupboard in bathroom @10ft away from bath tap.

Boiler downstairs in kitchen - a glow worm space saver.

Its on a shelf approx 2ft higher than bath tap.

Once its running, both hot and cold fine. Not quickest but will fill bath in @10 mins if full on.

Cold water tap on fine.

Hot water tap turn on to full nothing. Zilch. If turn it back, may get a trickle but generally, nothing at all. Timed it today was two mins exactly.

Live in hard water area and have probs with shower above it (single cold water feed cycling).

Has this always happened? What sort of tap? Is the cold water mains pressure into the bath, or gravity fed?

tap looks old fashioned style - it a Swalding Excelsior. Maybe need new washer?

Been over over a year and yes!

Cold water mains pressure or Gravity fed? No idea. How do I tell?

There is a tank in roof, programmer in kitchen and stat in hallway. Does that help?

Since it worked fine up to a year ago, a new washer would seem to be the first obvious thing to try.

(I was asking about the cold water spply in case this was creating a bit of back pressure within the mixer tap assembly and preventing flow)

Thanks all for help so far.
