Fix a small leak on your toilet water’s supply valve by tightening the shutoff valve. Place a wrench around the valve’s packing nut and give it a one–eighth.

Leaky faucets are usually caused by worn rubber washers, which give out over time due to valve seat friction. Replace the washers to fix your leak.

Plumbing maintenance should be performed every 18 months to two years, or whenever an issue arises with your bathroom’s plumbing.
