The system was installed properly and in a timely manner. The installer was friendly and polite and did nice work.
After the installer left I found little things that bugged me. He left metal shards in the sink and on the counter top from where he drilled the hole in the sink to fit the top. I also had to clean under the sink where the metal fillings were left.
I also noticed that the installer ran the plastic hose from the holding reservoir to the filters through the counter weight for my main sink tap shower nozzle. So now when I pull the nozzle from the holder, the plastic line for the filtration system moves and pulled with it. Also, of I choose to change the main tap I either have to remove and disconnect the filter hose or cut and destroy the main tap to remove it.
