Accumulator or cold water tank+pump

[sasha0120]

Hi

I own a flat on the third floor of a building. There is an issue with the building water supply due to which there is not enough water pressure and volume reaching our flat. At peak times of the day there is no water coming in the taps. Thames Water will not do anything about it because they guarantee supply of 1 bar at the building entrance and that is it. The building does not want to provide for a pump or tank to resolve the issue. Thus, I am left with trying to find a solution for my flat. I have a brand new megaflo boiler and have been recommended 2 options: 1) Install an accumulator that will provide a burst of 20-30min of water for a shower during peak times when the water supply is most impacted or 2) Install a cold water tank and a pump (or a pumped tank?) that will provide enough water supply. We have 2 bathrooms and showers in the flat. Option 1 is quoted at £1.5-£2.5k and Option 2 is significantly higher at £3-£4k. I do have the space in terms of cupboards for an accumulator or cold water tank. Attached pics of our current megaflo configuration. I would really appreciate some advice. Our new megaflo boiler cost us £3k last Decemeber so we dont want to spend on Option 2. However, I want to make sure that Option 1 works before committing to it. Any advice/help is much appreciated!

Has the mains water pipe up to your flat been investigated?

Has the pressure at the incomer been checked at peak times?

Are there other flats on the same level, if so do they have issues?

Is the incoming pipe to the building adequate for the number of properties?

Does a single pipe rise through the building and split to each flat or does each flat have it's own pipe from the point of entry of the main service?

I assume whoever fitted the new Megaflo did not investigate, otherwise they wouldn't have recommended the Megaflo?

Hi Snowhead, thanks for your reply.

THe answer to all your questions is that the water coming into the building is not adequate but TW is not going to do anything about it. The pipe carrying the water up is just 16mm wide so not adequate by any stretch. However, the only other flat in the third floor has a tank inside the flat and is not affected. The other flats complain of reduced water pressure but obviously we are at the worst end of the spectrum being at the highest floor. THe Megaflo was installed 7 years ago and hasnt been a problem until a few months ago. To be clear, the water supply is the issue so even the kitchen tap connected to the mains is affected. I am looking to find a solution to my flat so that I can be independent of the building and TW issues. I was proposed two solutions indicated above so looking for the pros and cons of the above. Thanks!

Agree but I would add the extra tank as well to give you around 800l of stored water enough for around an hour at 15lpm output with nothing coming in

Thanks for your input. Do you know if the pump will work alright with the megaflo and not interfere with its operation?

Thanks for your prompt reply! The description for the dabs systems says that it doesnt require any additional pump or tank? Do you still think we need a tank? Its for a rented property with a max occupancy of 4.
