New installation and bathroom-sink-repairNew bathroom sink installation and bathroom-sink-repair are the same because you just take out the old and put in the new sink. Just be sure to shut off the bathroom sink shut off valves. We will already have the plumbing all set up and waiting for the sink just like the other bathroom fixtures. Most bathroom sinks fit into specially made cabinets, but some are freestanding. Connecting the plumbing is quite easy. All it entails is to connect the drain line to the septic line and it needs hot and cold-water hook-ups. Most sinks have the p-traps installed immediately under them and it fits into the cabinet, but some freestanding sinks have the p-trap built into the walls or floors so you can’t see them. Usually toilets, showers, and bathtubs already have the p-trap installed because it’s part of the rough work, but for bath and kitchen sinks, the p-trap will most likely need to be installed after the walls have been finished and the cabinets have been made.
The above illustrations show how the p-trap assembly is connected to the septic line. The sink will next need to be put into a cabinet. The one-piece sink and counter top is very popular these days.
As we can see from the pictures above, the drain connects with the tailpiece. The tailpiece is held onto the sink with the underside locknut. The tailpiece extension then goes into the p-trap. Next we need to make the hot and cold-water connections. We’ll have to first secure the faucet to the sink by screwing on the locknuts on each water intake. In the picture below we can see the faucet with both intake valves. This will fit through the holes in the sink. After we tighten down the lock washers, we will put on each water line.
You will need two supply tubes. These tubes come in different lengths and they come in plastic or metal. They have fasteners at each end so they can screw onto the sink intakes and the plumbing waterlines as shown above.
That's about it for new sink installation and bathroom-sink-repair for modern homes. It's important to say once again that bathroom components can be very expensive or very cheap. The idea is to get good quality at a good price. If you shop at specialty shops where they sell extravagant products your housebuilding project will be over budget as most of them are.
