Hi,
I would like to share my experience on purchasing a water pump (Grundfos).I am renovating my bathroom along the way there was a need to install a water pump to boost the pressure for my rain shower.I looked for information regarding water pumps and learned that Grundfos was the best available.So I went around to a few of dealers to see the pump and understand the mechanism etc.However,the sales person in all the shops I went to kept on saying "Don't ask why (Grundfos);just buy!!!) and I was not given the proper explanation.So I surfed the net and found out thru this forum all the details and questions regarding the pump that have been lingering in my mind.I contacted Zean who gave me a very detailed explanation on the workings of the pump as well as the installation.He even had a demo unit which actually said it all.I was very pleased to deal with him as he was confident and sure with the product.Therefore,I would like to advise all those who wish to purchase a domestic water pump..."Go see Zean and he'll tell you why (Grundfos)".I am now a proud owner/user of Grundfos CH 2-50 PC.Thank you Zean!!!
