Last year when i had no money to hire an expert to remodel my bathroom, even though they were lots of affordable St. Louis bath remodeling expert, I opted for DIY and its was an interesting journey. Here are some things i did and I know it will be of great use to someone reading it;
1. Turn off the water supply either at the valve situated under the sink or at the main valve. Then turn faucet on to relieve any water pressure left in the lines.
2. Loosen the slip nut at the P-trap or remove the entire P-trap if necessary and catch any water left in the trap with a bucket.
3. Loosen the water supply lines with a wrench and disconnect them.
4. Use a utility knife to cut the sealant along the backsplash, then tug on the sink top so as to free it from the wall.
5. Assemble the drain and faucet on the sink before installation.
6. Apply a tiny bead of silicone adhesive to the rim of the sink opening but try not to get it on the face of the cabinet.
7. Set the sink top carefully on the vanity with the help of another person. Make sure the plumbing is lined up and also let the adhesive cure.
8. After the adhesive has cured, the drain should be reconnected and if the tail piece is too long, use a hacksaw to cut it.
9. Connect the water supply lines. If your water supply valves is old and faulty, you will need to replace them. Firstly, you have to turn off the water at the main house valve. If the pipe is a galvanized steel pipe, a pipe wrench should be used to hold the pipe and unscrew the old valve with a wrench. Clean the pipe threads and then wrap them with plumber’s tape. For installation of new valve, use a wrench to hold the pipe in place and tighten the valve.
For pipes that have soldered valves, use a propane torch to heat the junction so as to melt the solder, then remove the valve. In order to avoid burns, pliers should be used to remove the hot valve. Use a heat shield for this type of project. The next thing to do is to clean up the pipe and then attach the new valve with solder.
10. After the installation of your new valves, turn the water on and check if there are any leak. Attach the supply lines to the new valves.
11. Add a thin bead of bathroom caulk on the back edge of the sink.
12. Turn the water on again and test for any leakage. Make necessary adjustments.
