Before thinking about any work an investigation should take place to see if there are any issues that could be causing the low pressure. If the system is free of faults you could try raising the water tank but this wont make much difference unless you can raise it a considerable amount, 1m = 0.1bar. If you need to increase pressure for a shower the only way really is to install either a pump, power shower, electric shower or Combi boiler. If you already have a Combi and the pressure/flow rate is low, you could fit a home boost pump or maybe think about an accumulator.

In terms of pressure ensure your stopcock is fully open. If this is OK you may need to increase your incoming main pipe size directly from the meter, however this would really only affect flow rate of water being delivered unless your existing mains pipe was partially blocked. In short pressure cannot be increased without a pump, your water supplier by law only needs to provide you with a minimum of 1 bar incoming mains pressure, the only thing you can increase is your water flow rate by increasing pipe sizes, removing any small bore pipes and restrictions.

Water pressure is determined by the difference between height of the source and the height of the outlet. That is why in a setup where water is supplied from a cold water storage tank in the loft, pressure seems better downstairs than up. Pressure rises by .1 of a bar for every meter of height. So to raise the water pressure by 1 bar, it would be necessary to raise the height of the cistern by 10 metres!

Firstly there is a difference between Pressure and flow My advice is call a professional. Removal of flow restrictors may have an adverse affect on the item it was installed In most cases customers want increased flow not increased pressure . Water regulation do allow mains pump howler they also must not exceed 12ltrs per min If in doubt get advice from a professional.

To increase the pressure without a pump I would start by removing any flow regulators (these are normally inside tap connectors etc) and replacing/adjusting any pressure regulator that is on the system. Changing ball valves on the system from the common standard ones to the full bore valve. Changing any micro bore flexi hoses to ones with a larger bore or a hard pipe fitting if possible. If it is just the Hot water that has the low pressure then installing an unvented hot water cylinder can increase the pressure for the house.

Increasing water pressure without a pump can sometimes be achieved by simply removing and ripping any restrictions on the pipe affected I.e hard piping flexi hoses that feed taps and fitting full bore isolation valves. It's also worth checking the stopcock is fully open and in operation.
