[SIR Philbutt]

You say you have a plumber

Why can he not fix the problem is it because of the price he has given you?

Is the boiler a combi or not

Oil or gas?

Plumber suggests replacing the tap due to the restrictive bore.

We don't want to o this as its exactly the tap we want.

Combi couldn't keep up with a pump. The two are not comparable, so we have to have a hot water tank to feed said pump. As said this is on the landing.

Its gas.

Absolute NO No  in my book  . . .  .you should never  use a pump on a combi boiler

PM   sent  Chris

totally agree with this - If it's a combi you do not need a tank or a pump everythis should run from the combi at mains pressure

... obvious really, tbh. The whole system upgrade has been designed around the pump improving the shower. It was then improved further by increasing the pumps use to include all non mains fed taps. Good pressure, but bit noisy.

But with a combi and the header tank main cold looped to the header tank out would give mains cold to all taps with mains hot from the boiler. No need for any tanks or pumps. Do not understand why the config but obviously not there to see

I'm a plumber and I'm confused to opps lol!!!
Combi has to run on a min amount of pressure for cold mains so as it can be used for hot water,now some combi boilers can use a tank for supply to the heating instead of a filling loop at the boiler.
The hot water as your saying should be cylinder,storage tank in loft,min head required from highest hot water tap is approx 1meter,and any other taps on the hot water that are lower will have slightly higher pressure,mono block taps are not designed for use with a pump due to small bore of pipe,either 8,10,12 or 15 mm.
Also is there a non return valve fitted on the hot and a double check valve on the cold mains to tap?
Pump may not switch on due to distance from tap to pump as it needs to sense pressure being demanded,why not fit another pump with independent supply to kitchen tap instead

[Shackeng]

I didn't see if this is a combi or not. If so I agree that a pump should not be used.

[MR MISTER]

Just buy another fickin tap, tight arse.

Sorry, but nowhere did I say its a combi, it simply wouldn't work.

I'd like to activate the pump at touch of a button.

She won't let me change the tap. Prepared to spend money to change the system in order to keep it.

What are you for? Exactly? Useless bloody scouser

Is this when you didn't say it 

[Big_Al]

I'm butting out on this one now  . .  .  all too confusing for me

That's right, it couldn't. Can't. Won't. Wouldn't. Not possible. Won't work. If a pump is fitted, a combi couldn't keep up. 

Therefor it can't possibly be a combi

Well I read it the other way that could be read - confused even more so as a dragon would say "I'm out as well"

[martin42]

Can we start fresh,what hot water system i.e cylinder,elson tank,? where pump is situated,and where is cold storage tank

[chrisgixer]

Sorry but we're all saying a  combi can't work with a pump, which I said it had a pump, yet we're all asking if its a combi?

I thought Michele2.6 was taking the wee.


Anyway, this tap?

[martin42]

Are you using a shower pump?

Take it apart, clean out any crap.

Check the flexible connections for kinks. If possible fit solid copper tails - more hygienic & less resistance to flow.

Check the whole system, especially around the pump, for airlocks and kinked pipes.
