Hi, I am new to the forum. I signed up because I am volunteering in Honduras and some of the work involves plumbing. I am a DYI guy in the States but things are a bit different here and I am pretty much on my own. I need help getting connected with people who can help me figure out how it's done here! Any help is appreciated! Here it goes: I need to install a toilet and a couple of shower drains in a new construction. The drain pipes have concrete poured all the way up to the floor level with tile around them. The pipe is PVC SDR (sdr 35?) and the toilet drain is about and inch larger diameter than the flange that I have. Do I need a larger flange or can I reduce and adapt somehow to the smaller sch 40 flange? I am not opposed to doing some chiseling in the concrete which I am sure needs done but I need to know what to get at the hardware store before I go. If anyone has actually done work in Central America and could tell me how they normally do it here that would be best. They definitely don't have strict codes like in the states. Additionally the shower drains are metal and don't appear to have any way to connect to the pipe. I am guessing you just slide the lip of the drain inside the pipe and cement around them leaving enough space at the top for grout around the outside. Any input? I can try to get some pictures too.
