Tips 1: Before you buy a seat, you must find out the structure of the water pipe at home, and find out whether the water pipe is PVC pipe or cast iron pipe, without returning water bay. PVC pipe and cast iron pipe that is better distinction, one can see it, is the white plastic PVC pipe, cast iron pipe is a little rust. The pipeline belt does not have a return water bay, and the specific score is two cases. The first type of pipeline is exposed, and the structure of the pipeline can be clearly distinguished. The second kind of pipe is sealed in cement, so you can only try it with an iron wire. Instead of that elbow, the wire can be poke in a lot of bends, with bent tube, the wire of length can be impeded. If you don't have a water return bend, you should use siphon, otherwise it will be easy to return. Now the new building is basically PVC pipe.
Tips 2: How to measure the pit distance, after clarifying the structure of the sewer pipe, the next step is the pit spacing of the water. Toilet generally divided into horizontal, the two kinds of discharge water, can only be installed straight horizontal toilet seat, rows may be straight or siphon selected, depends on the specific tube structure. Generally horizontal distance 180mm, the discharge distance a little more complicated, there are 200mm, 305mm, 400mm, 580mm more like. Measurement is very simple, from the middle of the drain-to-wall distance is from the pit, horizontal measurement method is the same. When you are measuring, you should consider the thickness of the tiling. The manufacturer's toilet seat is 400mm, which is basically 380mm distance. The manufacturer reserves 20mm for the tiling thickness. If you measure the distance of the toilet seat at home is 370mm, don't worry, the diameter of the down pipe is generally 110mm, the diameter of the faucet is 70mm, and the middle can be adjusted by 40mm. It can be installed completely without worry! Hang from the amount is over, we want to start the election Toilet.
