1. Don’t block water supply valves or sewer cleanouts.

If you have a plumbing emergency, the last thing you want to do is fight with 100 under-the-sink cleaners, artificial plants, furniture, waste-baskets and other household items to access various water valves as water spews into your home.

2. Don’t close a tap too tightly.

When you close taps tightly, seals wear down faster. Be gentle with your plumbing fixtures to prevent the most common household leaks.

3. Don’t cut into walls, ceilings or floors blindly.

You may be surprised to find out how many pipes are in the walls, ceilings and floors of your home. Don’t ever cut into something in your home without knowing what’s behind there. Aside from rupturing pipes, you could also be getting the shock of your life.

4. Don’t attempt a do it yourself plumbing fix on a Sunday or holiday.

When easy plumbing fixes take a turn for the worse, having a plumber out after normal business hours can cost you more than your little project was budgeted for.

5. Don’t pour hot water into your toilet.

Toilet bowls are usually very cold. A drastic change in temperature can crack the bowl.

6. Don’t store things near your water heater.

Most people know enough not to store things near a furnace, but your water heater gives off an immense amount of heat as well. Be careful not to store anything too close to your water heater to prevent fires.

7. Don’t pour fats, coffee grinds or cooking oils into your drains.

These waste materials can build up in your pipes, or in sewer pipes, causing blockages, backups, and sewer overflows. A little mindfulness can save you a lot of money over the life of your home.
