Hi

Just keeping you guys informed of our latest test results.

We tested the claims of suppliers of water saving shower and tap nozzles with regard to reduced water use and hence reduced energy used to heat water.

Our test and its results are posted here:

We hope you find them useful and interesting. If you have any suggestions regarding possible future articles please let us know.

Heh - the right nozzle is a blessing. We have very bad water pressure in the one bathroom, and installing one of these has made the shower usable.
 
I have been using these nozzles for ages. Not the RST, as I found the spray too narrow, but another brand that I bought from Builder's Warehouse. This one has a nice wide angle of spray. Works like a bomb...

We also got poor pressure in ours.

What brand did you use?

El cheepo Builders Warehouse - no bloody idea! :p
Takes 30mins at least (no exaggeration) to run a bath in that bathroom, and the shower with taps on low has a lot of force.
 
Quote from the report:

Some personal observations:

* The RST shower nozzle definitely uses far less water. This was immediately evident in the time taken for hot water to reach the shower from the geyser.


I don't believe that the time taken for hot water to reach the shower from the geyser could be shorter than before as the flow is lower and therefore it should take longer to get rid of cold water in the pipes.:confused:

As I read the quote, it can mean either longer or shorter. I this case longer is meant.

Sorry of this was unclear. I takes about twice as long for hot water to reach the shower now after turning on the tap.

Do you know what the model or price was?
 
The price was around R120-00 each, but I will have to come back to you on the make. I comes equiped with a shut-off valve, so one can close the water while soaping in (or shaving). Works forme.
 
Thanks alanB for this thread, now I also got a decent shower!! :)

I have bought the shower head AQUAtrend DX5123CR, which has 8 different settings, from Builders Warehouse which they have on a special at the moment for R79.99.

It definitely reduces the flow which is evident as my shower drainage could not evacuate the water of the previous shower head fast enough, now it's no problem.

The only problem now is that I don't want to leave the shower.:D

One observation about shower heads which have a tap to close it of completely is that they might potentially be dangerous on systems where the cold supply is not on the same regulator as the geyser and the local water pressure is high. Normally the geyser supply is regulated at 400 kPa and suppose you have 800 kPa municipal supply pressure you might unknowingly put the geyser under that higher pressure as the cold and hot water outlets are now directly connected. A one way valve in the hot outlet to the shower or the reconnection of the cold supply so that it is through the same regulator as the geyser would solve the problem.
This situation will occur mostly in older installations where only the geyser supply is regulated. The old Latco valve type installation is one example and the old gravitation type geyser also come to mind.

Pardon for taking so long to reply. The low flow shower head I bought form Builders Warehouse is simply called "Solid Brass Shower head" Model HC-513. Comes in a kiff cloth pouch. R129-95.
 
any pricings available for these "Aerated Water Nozzles" that they talk about in the article?
