If your toilet runs continuously, the flapper is likely worn. Turn off water, flush to empty tank, remove old flapper, and install a new one. Cost is low, water savings high.
If a door sticks, check the hinges. Tighten loose screws or insert shims. If the door is warped, plane the edge slightly to fit the frame.
Turn off all water fixtures. Check the water meter; if it moves, you have a leak. Common culprits are toilet flappers and faucet washers. Replace them to save water.
Apply silicone caulk around tubs and sinks to prevent water damage. Remove old caulk, clean the area, apply new caulk, and smooth with a wet finger.
For clogged drains, use a flange plunger on toilets and a cup plunger on sinks. Ensure a tight seal, push down gently, then pull up sharply. Repeat 5-10 times to create pressure waves that dislodge blockages.
For small holes, clean the area, apply spackling paste with a putty knife, let dry, and sand smooth. For larger holes, cut a square, insert a backing piece, and cover with a patch.
