I woke this morning talking in a dream about asking someone if they wanted to pay $10,000 for a plumber...? This afternoon i am googling reverse osmosis water filters for the home water? I happy to spend money for a really good water filter to fit under the sink...what do you recommend anyone, do i need one for kitchen and bathroom....I have a filter on my shower head of copper but that is only a baby filter...I mean the mother of all filters?
