insulating water pump

[kherbert]

hi
i recently installed (well my plumber did) new mixer taps for our kitchen but the hot water pressure from them is awful, i have been reading other posts trying to get some info but am not sure what are my options to increase the water pressure .
The cold from the water mains is great so it is only the hot water that is weak.
The taps are 1/4 turn taps and so i am going to try monobloc taps as well, as this was suggested might help. but i was told that the only way to really increase the water pressure is to link the kitchen hot tap to the water pump, which is a stuart turnere pump. the noise tho is preey bad and i was wondering is it possible to insulate this type of pump to reduce the noise, or dso i have any other option left to me?

thanks

Is the hot water supplied from a cold tank in the loft (so low pressure) but the cold from the mains (so high pressure)?

What country were the taps made in (this is not a joke).

hi
the hot water comes from the tank in the loft, yes (as far as i know) and the cold is mains fed

the taps are 'Franke', but may have been madein switzerland ( according to my kitchen fitter)

Most countries have high-pressure water, so their taps are not as big inside as British (and I presume Irish) ones, so will not give good flow from low pressure.

yes, i heard that alright, do you know if it is possible to insulate the water pump? its inthe utility room and so quite noisy.....

thasnk for all you replies...

The pump should be mounted on a paving slab with a layer of 15 mm rubber on top to minimize vibration leading to noise. Donot bolt down the pump unless mnftr advises so.

thanks it is currently mounted on a piece of wood attached to a stud wall- it only has rubber feet on it,
can it be boxed in and insulated do you know?

They can overheat if you do that. Is it on proper special flexible rubber pipes? No noise should transmit down the pipes.

 

[kherbert]

no i dont think so, it has little rubber feet and then it is sitting on a piece of plywood. the pipes are also attached to piece of wood and then attached to a stud wall, so i think that isnt helping the noise
where can i get the rubber pipes?

Someone else suggested lagging the pipes...?

pipes are also attached to piece of wood and then attached to a stud wall,

About the worst thing you could do!

Try your local plumbers merchant for the right sort of pipes.
They usually come with the pumps, eg as shown here

(I hesistate to recommend them but I have seen ordinary tap connector flexible pipes put on a shower pump. They've been there about 17 years and not leaked yet...!)

I place the pump with its rubber feet resting on a paving slab but I also put the slab on a foam bed is available or a few carpet tiles if not.

sorry, there are flexi pipes attached to the pump alright and then they in turn are attached to copper pipes that are fixed to the stud wall, i will ask plumber to maybe move the pump to the floor and then put a piece of foam bed or carpeton it..many thanks for all the replies....

Does anyone know if you can get a silencer for this pump?

Demon Tweeks do a 4 inch stainless one with DTM end pipes it is quite expensive but it looks the mutts bits.
