Tap water pipe diameter is 4 but Delta valve inlet diameter is 20MM which is four minutes also said that four points is 15.5MM 1 in the end is the former or the latter right? 2 if the diameter asymmetry is not to add to the deflection member? 3 triangle valve and tap water pipe is connected is not to add raw materials, raw materials with how to add 4 good (circle) and then to add without gasket is better?
All screw connection must be filled with raw materials (or, from Bai Houqi, et al. Screw connection on the washer.

Caliber of water supply triangle valve:Any use of points, inch (inch) of the pipe, joints, valves are refers to the tube diameter, 4 points equal to 12.7MM., some stores use 15 means, refers to the pipe diameter, now production plant has been implemented outside the table diameter
