Dear, good afternoon! I am Diego and this is my first question in the forum. I describe more or less the situation, I live in a ph with 2 houses. In the main one there are 2 bi-layer plastic tanks I think connected in series. From there it feeds the main house and then our Dolmenit tank (300L) which is geographically with lower altitude above my house. So far there is no drama. The problem is that I want to disable the tank (for health reasons, the commercialization and use of these tanks is prohibited due to the abscess) but I have the following dilemma. Pipe that feeds my 1 "tank Pipe that goes down to my house (measures 42.2 mm outside) so I read it would be 1 "and 1/4 but they don't give me the calculations. It is plastic and terracotta color, like the ones commonly used here. (Not thermofusion) I want to disassemble and connect the 1 "pipe directly to the one I mentioned but I would not know what happens, connection or whatever it is called I need. Thanks atheist!

Hi. for this you need the pipe, a double union and the necessary reductions to join both diameters. It is not a complicated task. In a hardware store you can find everything you need. It is called polypropylene thread. Regards

Your terracotta pipe is PPN can be suitable for fusion ... get reduction to 1 "and you can join the 2 with a quick coupling of 1" .... put double Union and others if you do not have much knowledge. You will deny.
