The not quite suitable for the Intex pool besides Elecsa solar heating degree were me by the customer reviews here known. Have bought the bypass already in winter at a known auction house for just under half, further favorable hose connectors and reducers, hose I had plenty. In addition, our construction market has dissolved his pool range, so I could not resist for 1 Euro / piece or per roll of Teflon tape. This considerable meter Teflon tape are also needed for tightness, especially for the tee, as write other users here that are deducted. Another star I pull for the resistance to a written instruction from (only if the pool heater is a diagram), also because of the lever position of the valve, this should be a German manufacturer. If I have time to do anything else, I will concern myself intensively with the kryptsichen lever position of the 3-way stopcock, logic is nothing (just trying).
