Give me a Strong Shower!

Why would I want to switch from a low pressure to a mains pressure hot water system?

The most common complaint people who have a low pressure system make is that their pressure is poor at the tap.  They want to luxuriate under a decent spray for their morning shower, not shiver under a dribble.  Another problem some experience is difficulty controlling water temperature with mixers.

 

What’s the difference between a low pressure and a mains pressure hot water system?

It used to be that all houses had low pressure hot water systems. The cold water from the street “main” usually went into each house’s supply tank, most commonly in the ceiling.  The water was then gravity-fed down to the hot water cylinder.  Alternative to a supply-tank set-up, a pressure-reducing valve was installed.  These systems were designed to reduce the water pressure because the hot water cylinders couldn’t withstand the high pressure of the water coming from the mains pipes.  More recently, hot water cylinders that could withstand the pressure from the mains were developed.  Water could be fed  into them straight from the mains pipes with a pressure-limiting valve, instead of via a supply tank or through an old-style pressure-reducing valve.

 

What does switching from a low pressure to a mains pressure hot water system involve?

The supply tank is disconnected or the pressure-reducing valve removed.  New pipework is then installed to carry cold water from the mains pipe to the new hot water cylinder.  A number of valves are also installed.  The pressure-limiting valve controls the pressure of the water as, ironically, it can also cause problems if it’s too high.  (You may be interested in our post Get Your Water Pressure Checked!Craig would be happy to come and look at what would be required to make the change at your home and provide you with an obligation-free quote at no cost.
