Pipemasters Specialise in making your water hot

Piping hot water, good pressure, economic use of energy and most of all a great shower. We know when it comes to hot water there are far more options available than the old hot water cylinder that was so inefficient you could dry out the whole family’s laundry- electric, gas and heat pumps, technology has given us options- take a look at what might best suite your house.

Electric Hot Water

Converting to mains pressure from low pressure electric, using a combination of electric and solar, maybe a mains pressure wet back- We know the in’s and outs of electric hot water. There are so many options these days depending what you want to spend. Electric is a simple way of heating hot water and your hot water cylinder does not need to be inside if your really struggling for space.

Gas Hot Water

Gas, Both natural and LPG are available in the bay depending on where you live. Gas can be a excellent and efficient method of heating your water. There is no running out of hot water because the kids took too long in the shower. Gas can also be combined with a storage tank and solar to create even more efficiency. Pipe Masters can Certify this gas work and help you to get the most out of your investment.

Heat pump (Air to water)

Air to Water heat pumps developed in Europe converting the same reliable technology used in refrigerators to extract heat from the air and transfer it into the water, this is quite common practice by our north hemispherian neighbors and now New Zealanders are cottoning on. These units can operate down to -7°C and reduce energy use by up to 65% compared to a conventional electric storage hot water system. Pipe masters can offer well priced air to water options for your household.


Check if you have low or mains pressure hot water based on the types of valves you have feeding you hot water cylinder. What is commonly referred to as the ajax valve means you have a low pressure system.



You probably have a low pressure hot water cylinder. This can be identified by what is commonly refereed to as the ‘Ajax’ valve, having a copper pipe sticking out of your roof or the obvious ‘low pressure’ label on your cylinder.

Within the low pressure range, you may still have really good cold water pressure- This is known as an ‘unequal pressure’ hot water system.

If your looking to install tap ware on this system, ensure its suitable for the pressure type, buying the wrong tap may leak to a dribble.


You have a pressure limiting valve releasing water through the valve. You need to either adjust the valve by turning the bottom screw to wind back the pressure, replace the washer inside or replace the valve and reset it. The last of which is the best option if the valve is quite old.

This problem is worth getting looked at- not only is it a waste of water but this is water that has been heated up, so you have already spent money on it.


First port of call is to check the switch in the hot water cupboard has not being inadvertently been switched off, secondly the circuit breaker on your switch board is not tripped (normally labeled hot water). If both of these things are all good you have one of a couple of options.

Either a) the thermostat or element (or both) has failed and will require replacement or b) the ripple control has tripped. The ripple control is a circuit normally on the main circuit board that is able to be switched on and off by the power board to manage peak energy flows, Sometimes these fail and your utility power supplier will come and replace it. Normally an electrician can bypass this to get you up and running.
