Vaillant Turbomax 824E. Want to refill with water and build up the pressure. Any advice please?

- Combi Boiler Water Pressure Issues?
We recently had a combi boiler installed in our rented property. Initially the plumbers left the cold water feed from the tank in the loft so the combi boiler was only supplying the hot water. Unfortunately due to the differing pressures (i think), the cold water feed was excessive whilst using the shower the overflow pipe from the loft rained from the side of the house. The plumbers have since rectified that problem by removing the cold water tank and using the boiler to supply both the hot and cold. Unforunately the water pressure is now so low that it takes 30 mins to fill the bath. Also the shower now operates too hot and eventually (after a few mins) runs cold then hot again. Any help would be appreciated.... - Is a thermostatic mixer shower or electric better for combi boiler sytem with low pressure?
I intended to fit a thermostatic mixer shower with my new combi boiler heating system. However, the plumber has advised me that the water pressure I have is so low that the water flow would be poor and that for a more enjoyable shower an electric shower would be better. Is this correct? I have sought advice from various plumbers who all give different advice. Please help.... - Why does pressure of my combi boiler slowly keep going up to 3bar over a few days? It was ok when installed?
The bioler is Worcester 28CDI combi Fanned Flue RSF. The seals broke due to the 3bar pressure and was repaired by plumber. He said to bleed radiator to reduce pressure if it happens again, but this is a continual fault now.... - I’ve just moved into a new house with a combi boiler. What pressure should the system be at?
The pressure was low when we moved in, and we’ve upped it to ~1bar – but I’m not sure if that’s right. Nothing useful like manuals in the house, either.... - Why does my combi boiler pressure shoot up to 3bar?
I have a Baxi combi boiler (installed just over a year ago) and it has ran fine (opperating around 1.5-2bar) up until the 1 year warranty ran out (sods law!). Now when the system is off the pressure goes right down to 0bar. When I turn the heating on it goes up to 3bar. I have checked for leaks and bends/blocks in the flexi pipes (which there aren’t any) and also bled the system. When I turn the heating on (from 0bar pressure) the boiler makes cluncking sounds. Anyone have any ideas before I fork out a tonne for the plumbers? Thanks...

I’m not sure if we have the same model or not but i have a valiant combi boiler. underneath the boiler there are two things you can turn. turn them 90 degrees and the pressure gauge on the boiler should go up. once the pressure is back up turn them back 90 degrees again.
on my combi boiler there is a tap which you open to let in water and build up the pressure find one that shut open it see the pressure rise on the gauge and shut it back off..
You should have a repressure valve on one of the pipes near the boiler. It should connect with the mains, usually by a flexi hose. Turn this tap on to repressure but don’t over do it.
If you are having to top up a lot check for leaks. You’ll have no CH until the system has enough pressure. It shuts down as a safety measure.
You should have a filling loop flexible hose which coonnects from mains water to CH Flow or Return via a non return valve. connect this and turn tap on to fill your CH up to pressure normally 1.5. You may need to bleed rads of air especially farthest away and highest one.
The normal pressure is one and a half bar.
As others have said their should be a stainless steel flexible pipe with a tap at one end – this is connected to your mains pressure fresh water pipe. Turn on the tap and watch the pressure rise. Pressure drops due to badly made join in pipework, join is good enough to stop water spurting out but, not good enough to prevent water vapour (a very fine gas) from escaping. So, over time pressure drops.
If i remember correctly the Turbomax combi should have a “built-in” filling link. If you look under the boiler where the pipes connect to it you should see a silver braided hose which is quite thin. On both ends of this braided hose there should be small black things which look like little levers. Turn one of these a quarter of a turn and then turn the other one the same, you should hear a rushing sound which is the central heating filling, keep your eye on the pressure gauge on the front of the boiler and when the pressure reaches between 1 and 1.5 bar you should turn both or these little levers back to their original positions (i.e. the OFF position) Your heating system has now been filled (or topped-up). You should probably bleed the radiators after doing this. Ensure you keep an eye on the pressure gauge because as you’re releasing air this will cause the pressure to drop slightly. As long as the pressure in your heating system is between 1 and 1.5 bar when cold you should have no more problems.
If the pressure continues to drop after you’ve filled it up then it’s either gonna be a leak somewhere on your heating system or maybe a faulty expansion vessel or Pressure relief valve. If this is the case then you should contact a qualified heating/gas engineer.
Hope this has helped??
Look under the boiler there should be a hose attached between two pipe’s ? look to see if there is a tap, or screw driver union between the hose and the pipe? this is the filler valve for the boiler.You will have to also look for the pressure dial,fill the boiler to the recommended amount ,this information should also be in the user manual
use the tap on the filling loop
