Components used in mains
pressure water storage systems |

Watts Industries is one of the
largest valve manufactures in the world it is no surprise
that Watts UK is superbly placed to understand and flow with
the constantly changing needs of the marketplace.
A key part of Watts UK's business is the supply of valves
to Original Equipment Manufactures (OEM's). Watts UK specialises
in the supply of polymer check valves to the domestic and
commercial shower industry, air elimination and safety valves
to the boiler industry. |
| |
| The Watts Group world-wide
is the leader in the supply of back-flow prevention devices
and this is reflected in the range of these products offered
by Watts UK. The recent move to Water Regulations in the UK
demands that a large range of back-flow prevention devices be
available. |
| |
| |
 |
|
Watts UK can not only supply any device required but also
advise on its use installation and testing requirements. Grant Phipps ,
former Managing Director of Watts UK limited discusses some of the critical
components used in the design and manufacture of mains pressure water storage
systems. |

Water
pressure reducing valves
Where a new water main has
been laid to service a new development such as a new Hospital
or commercial estate, water pressures could rise to above
10 bar, this may cause damage to older existing installations
due to the stress caused by increased water pressure on pipework
and joints. |

Temperature
and pressure relief valves
Most consumers take for granted
their hot water supply and rarely think about their water
heaters once they have been installed. Where water heaters
are concerned, "out of sight" is usually "out
of mind." and to date, many are unaware of the need to
have their water heaters regularly maintained to prevent water
heater explosions. |

Thermostatic
mixing valves
Every year, thousands of people suffer
serious Thermal Shock or Scalding injuries in their bathtubs,
sinks and showers. Often, injuries in the shower are caused
by slips and falls in reaction to a sudden increase or decrease
in water temperature. |

Discharges
from un-vented cylinders
The 1986 Model Water Bye-laws stipulate that unvented storage
water heaters should incorporate a means of accommodating
expansion, and a factory-fitted temperature relief valve.
This requirement has not changed with the new Water Regulations.
Paul Rivett, Technical Director, Heatrae Sadia Heating Limited
discusses the issues. |

Titanium
immersion heaters
The variations in modern water supply
mean that careful thought should be given to the selection
of immersion heaters, especially when replacing failed units.
The standard immersion heater uses a copper sheath but nickel
alloy sheathed immersion heaters are the traditional alternative
for aggressive conditions. |

The
cylinder thermostat
The cylinder thermostat is the first
level of safety and is usually set to operate at around 60
- 65 degrees C. |
