Do you inform yourself about the construction of the water connection and the waste connection? Where to go if you understand something else, but this is a Spanish village for you? Can anyone advise you how to do it with the sewer as best and quality as possible? The best way to do this is to contact a professional company in the field of water connections and other installation activities. If you are interested, order and sign the work contract.
Not a company as a company
Experienced employees of a reputable company will soon start to participate in your order. That is, if you have properly tapped it and used to get references, read reviews, or collect information about their previous construction activities. In a positive case, you can also use their other offers-in addition to drains usually also the work of heating and gas.
