Hi I've noticed the pressure coming out for both hot and cold water supplies upstairs (megaflow is on ground floor) has reduced a bit over time.

I thought that it could be the mains pressure that was less, so I turned the stop clock open more if that makes sense that did not help much but I noticed that the pressure in the shower upstairs and the taps is somewhat reduced than compared to in January when the system was installed.

Also if someone is using the shower upstairs, the water pressure downstairs is somewhat reduced. I don't think this is normal, is it? I'm pretty sure 6 months ago that this would not happen.

what could be causing this issue? Any ideas? Nothing serious I hope!

If as you say the pressure has dropped both on the cold taps and the hot taps, then it has to be a cold supply pressure issue. Re-Pressurizing the Megoflow will make no difference.

It is two issues

- upstairs wc taps poor flow + shower
- using two outlets at the same time yields poor pressure

Whatnwill make a difference?
Think repressuring the system like mentioned by other person is worthbtrying


I saw a youtube video where the water valve is shut off, the closest hot water tap is ran then the pressure release valve is opened for 20 mins or so
Is that repressuring the megaflow??
 
Yes there are lots of valves down there
Provide pics later
It might need cleaning

Im guessing the whole valve needs to be taken off and cleaned out?

Surely Cant be faulty just got the damn parts new 11 months ago
 
If someone is washing the dishes downstairs and I am trying to have a shower upstairs surely the pressure of the water from a megaflow is not dramatically reduced?


Im sure back in the earlier part of the year
One could use two showers and wash dishes in sink for the pressure to be pretty decent everywhere
What u all reckon?
 
Thanks for the reply guys

I tried that repressuring but as you all said didnt make much difference except perhaps downstairs pressure slightly better.


However Upstairs pressure isnt what it used to be. If i turn the shower on then the taps slow down and vice versa

Fezster and dandle thanks
Im going to get a pro in As not confident draining the system myself
 
How much should i be looking at to get this fixed?
Still have a warranty on the megaflow i might ring and ask them too

I'm not trying to be funny here or anything like that psd99, but have you read the replies to your thread ? Your problem is almost certainly the incoming mains pressure and has nothing at all to do with your Magaflow.

You need to be talking with your water company and peeps next door to you to see if the water pressure has dropped for any reason. There could be a mains leak a few hundreds yards from your house that nobody knows anything about.

It feels like the problem is somewhere between the ground floor and the first floor


Downstairs the pressure is ok so that would rule out a problem with the water coming into the property no?

Upstairs now the issue feels intermittent
Sometimes it is ok
Other times it just is so poor! Very much hit and miss.

Will ring the plumber up to discuss this. Do let us know your thoughts and feelings towards this issue
 
In no particular order:









UPDATE:

- Hot water is reasonable now both upstairs and downstairs
- Cold water is not so great everywhere.
- Worse in upstairs bathroom the shower has very poor pressure now.

must be the pressure coming in as mentioned a lot on here! I will also ring water company about this too just out of courtesy.

I haven't rang the plumber yet but I had a question about the stop clock (main water supply coming in)

I'm sure it is quite open but does it need to be fully open or just a quarter turn?
