I am having difficulty with my kitchen hot tap water speed

[joolzhaines]

Hi,

I am having difficulty with my kitchen hot tap water speed, just recently I replaced an old leaking tap with a new one and ever since doing this the water from the hot tap is very slow, while replacing the tap I turned off the cold water via the main stopcock and turned the boiler off, I was told by one person that I may have an air bubble in the pipe and that I should try and flush out using the cold water pressure is this correct as I can do this?


I could try and get another tap to test but I cant see why the tape would be at fault as the cold is working fine.


The system is an open vented hot water tank in the airing cupboard and water tank in the loft,
the boiler is in the kitched next to the sink.

Thanks
Julian

What was the minimum recommended working pressure for your new tap?

 

[WaterTight]

Generally 0.1 and 0.2 bar should be ok if the tank is in the loft. 0.5 bar type taps could well cause probs. Other than that you may well have an airlock or (if you drained your tank in the loft) a blockage.

Hi,

Thanks, there are two stop cocks under the sink so I did not need to drain anything, how do I tell what bar the tap is as I dont have any documents, the tape is a combi hot and cold with a directonal hose on a sping,

Could the hot water speed be increased by a pump under the sink?

Regards
Julian

Sounds like your tap is a continental tap designed for higher pressures as kitchen taps with the pull out hose do not comply with the water regulations. You need to change it for one with a bi flow spout designed for the plumbing systems in this country.

Sounds like your tap is designed for high pressure supplies.

Pump under the sink is a bit drastic and costly plus it opens up a whole can of worms with leccy supply.
Cheaper to get a tap designed for low pressure supplies.

i agree with the other posters your taps aren't suitable for your system. on the instructions it probably said something like min 0.5bar which would be an absolute minimum imho. underneath the taps, are the connectors flexi hoses? this will cut down on flow as well.

This is often the problem when novices see a shiny new tap in the store and think it will work the same as their old one.

Most modern taps have ceramic discs and are not the original spindle and washer type. Much greater working pressure is required for these taps to function properly or they could have a shortened service life due to lack of pressure casusing the cartridge to prematurely wear. 5m head is considered the minimum for correct operation.

Either that or it's a kinked flexi!

Don't get me started on flexis again.....
