Hi,

I just install a Grundfos CM3-5PC and the water pressure is very strong, I have 4 bathroom. My wife is complaining that the pressure is too strong.

Now I may have a problem as I have Water Heater tank installed for every bathroom, the Groundfos is install to supply pressure to all including all the water heater tank. So now even the hot water comes shooting out. Just imagine if I turn the Shower Mixer lever all the way to the left only hot water comes shooting out. I could be cook now I am looking for Shower mixer that can limit the flow of hot water like limiting the lever from turning all the way to the left. Any suggestion ?

Hai WeiKee,

I have a single lever shower mixer wall mounted type. Pulling the level up will turn on the water flow. Middle position I believe will be 50% hot 50% cold but if I mistakenly turn all the way to the left 100% hot water will come out. I want a mixer that can limit the max amount of hot water to comes out because right now both the hot and cold water have the same pressure.

Any model that can regulate or limit the amount of hot water out.

Hi Weikee,

Yes I know we can regulate how hot and cold we want by just adjusting the lever up and down left and right. But what I want to to LIMIT in case of we sometime forget or the wife or friend or kids turn the lever all the way to the left and 100% hot water shoots out.

The model I install now is Rubine RT-SP022CR Bath Shower Mixer and I actually wrote to rubine.com.my customer services. And their reply is that they do not bring in model that can regulate limit the amount of hot water. There are model that are thermostatic and would works if both side has the same pressure and would be able to regulate the amount of hot water mix. And I also google and found that there are Mixer that can adjust the max angle the level can turn to the left to prevent 100% hot water.

My problem is that the hot water also same pressure and volume and accident is just a turn of the level to the left. A pressure reducing valve on the hot water side would be my last solution.
