There are a lot of reasons you may have low pressure, here are a few ways to fix/ increase pressure. - open mains water stopcock fully and any isolation valves - install a pump/mains boost - Install accumulators - change the float valve diaphragm if it the toilet filling too slowly - clear any airlocks

There are lots of reasons for poor water pressure. It the system is gravity feed then you only have the head of water creating the pressure. Many systems now are fed directly from the main, such as an unvented cylinder or a combi boiler. If the incoming pressure is too low there are options such as pressure boost sets or accumulators. Both of these work very well in increasing the pressure.

Increased "water pressure" can only be achieved with a pump and most are only set to a certain amount of pressure anyway. Your water supplier only legally has to provide you with a minimum of 1 bar and that cannot be changed, this is rare but it can happen. Installing an unvented cylinder WILL NOT increase your water pressure, if your incoming mains water pressure is low, unless your incoming cold water main is 3 bar or over an unvented system will not function correctly. If you have great water pressure but you have a gravity hot water and heating system resulting in your outlets being of low pressure then our advice would be to change it to combi boiler or an unvented cylinder but only if your incoming flow rate or mains pressure reaches the manafactures recommendations. You can increase your water flow rate by upsizing pipework, removing restrictions and increasing your mains water pipe size from the meter. You can also get a mains boost pump that is set to 12pm which would cover the requirement to fit some combi boilers if your incoming flow rate was to low. There is a common misconception that pressure and flow are the same thing, this just isn't correct, there is a huge difference between the two.

For low pressure on your incoming mains cold water there are booster pumps available. Some pre checks if this is suitable for your home must be carried out and to check your existing low pressure fault is not the existing pipework or valves. BoilerOne recommend you consult a verified plumber to diagnose the problem

Firstly you can check to see if your stop cock is fully on. If so then there are a few other options: Mains booster pump’s can be fitted to low incoming water mains, or possibly a new water main can be fitted if there is a problem with the existing supply. If the hot water pressure is low you can change your system to an Unvented hot water storage cylinder to provide good pressure with high flow rates. You can boost pressures to a shower (if the shower is fed via a hot water cylinder and storage tank) by fitting a shower pump. Some mixer taps come supplied with small bore tail flexis which do not work well with low pressure hot water supply, these can be changed for larger diameter flexible hoses

You have a couple of choices to fix low water pressure or to just increase it. If just the hot water then you can install an unvented system. this will give you the same hot water pressure as the cold water throughout the house. If you have a cold water storage tank in the property, then a pump will solve this for you. If you dont have a cold water storage tank you can install a powertank to increase the pressue and flow. You must have a storage tank if you want to fit a pump, as byelaws in the UK prevent the fitting of a pump to mains water.
