Aquanomic

Leisure Sinks’ range of Aquanomic taps have been developed to cater for the demand of flow restricted kitchen taps, in accordance with the Code for Sustainable Homes. Our range consists of four tap models, with a mix of monobloc designs for single tap hole sinks and pillar taps to suit sinks with two tap holes. The taps include a factory fitted flow restrictor within the spout, this ensures no extra work for the installer as with retro-fit solutions. The flow of the tap is limited to 3.8 litres per minute, per tap, and a non-return valve is fitted as standard (with the exception of the Pillar Tap).

What is the code?

In 2006 the Government announced a 10-year plan, which set a target for “All new homes from 2016 onwards must be built to zero carbon standards”. 

The Code for Sustainable Homes was launched in 2007. It stated from May 2008 all new homes built are required to have “a code rating” (The rating is from 1-6 with 1 being the worst rating and 6 being the highest) the ratings are based upon standards set in the “code”. Homes with higher ratings will be more energy and water efficient, which leads to producing fewer carbon emissions and are better for the environment. For the homeowner it will mean less waste being created with a home having lower running costs.

Water usage is one of the nine categories used to measure each homes efficiency and rating. The code aims to “reduce the consumption of potable water through the use of water efficient fittings, appliances and water recycling systems”.  This includes products such as laundry appliances, dishwashing, showers and baths.

Within the water usage section of the code is a “water usage calculator” this works out the amount of water used in the home by the house builder adding all the flow rates of all the appliances & fittings for that particular home. Based upon the guidance notes produced for the code and feedback from research with customers we have developed a range of Aquanomic taps to meet expectations.

Installation Guidance

The Aquanomic taps have been developed to save water (in line with Part G of the UK Building Regulations), therefore the following points should be adhered to so that the tap will work to its optimum level:

  • It is essential that the water system is thoroughly flushed through the supply pipes in order to remove any remaining solder, swarf or impurities from the system. It is recommended to carry out this procedure as it may cause problems or damage to the workings ofthe tap and invalidate the warranty.
  • The water pressure should not exceed 4 bar / 58 PSI, as high pressure could damage the filter in the tap or cause spluttering.
  • The water temperature should not exceed 70oc / 158oF as high temperatures could damage the filter.
  • Ensure that the spout retainer collar (if applicable) is firmly tightened after installing the tap.

The Aquanomic water saving taps function differently to non-water saving taps, therefore it is advised to be aware of the following factors when choosing any water saving product:

  • -The hot water will take longer to flush through any cooled water in the supply pipe  to the tap exit from the heater. A lower flow rate will take longer to heat any  plumbing between the heater and the tap so piping distance should be kept as  short as possible.
  • -Some instantaneous water heaters or pumped hot water systems will require a  minimum flow to initiate the hot water system. When the tap is in a 50/50 mixed  position the hot water flow could be approximately 1.5 litres per minute and  compatibility should be checked accordingly.
  • -Large capacity sink bowls will take longer to fill than a non water saving tap.
  • -The flow limiters used in Aquanomic taps are produced to a high degree of  accuracy. Dirt and debris can affect their correct function so it is important to  flush the system before the taps installation and periodically clean the flow limiter  to maintain maximum performance.
  • -Pressures lower than the above or imbalanced hot and cold pressures may produce  flow rates different from the example above.

 

This advice is in line with recognised best practice plumbing guidelines. By choosing an Aquanomic tap it is helping to preserve the environment, and saving money on water and energy bills.
