With a screwdriver and this step-by-step know-how, you can save water at home by fixing one of the most common toilet problems: an unbalanced water level in the water tank.
The level of water in the toilet tank should be a half an inch or less below the overflow tube.
The following is an excerpt from If I Had a Hammer by Andrea Ridout (HarperCollins Publishers, 2008). No matter your DIY needs and no matter whether you’re a DIY novice or expert, home improvement guru Andrea Ridout has ideas, advice and expertise to share with you in her book. This excerpt is from Chapter 3, “Beautiful Bathroom Boosts.”
Of all the plumbing repairs around the house, fixing the commode is the one that typically gets done most quickly. If you’re like me, you’ll agree that having a quiet, nonleaking commode is important enough to learn how to take care of problems when they first rear their ugly heads.
The toilet is the most common household water waster. A badly leaking toilet can waste nearly 80,000 gallons of water a year. While repairing a leaky toilet is a major water conservation project, it is actually a very simple plumbing project. This diagram and the following instructions can help you understand the inner workings of your toilet and make adjustments as needed. For more troubleshooting with your toilet, visit Professor Flush.
One of the most common toilet problems is excess overflow. This often happens because the water level in the tank is not balanced correctly. The water level should be a half inch or less below the overflow tube. When the water level in the tank rises above the overflow tube, the water will run into the toilet bowl constantly. When the level is too low, the toilet may not flush fully. Luckily, both problems are easily fixed with a screwdriver and a little know-how.
1. Determine the flushing mechanism. Most toilets have one of three different types of flushing mechanisms: a float arm, a float cup or a metered fill valve. A float arm looks like a balloon on the end of a metal rod, the rod part being the “arm.” Usually, the float is made of black rubber, but it can be made of other materials as well. A float cup has the float part wrapped around the refill pipe rather than on the end of a metal arm. A metered fill valve is found on older commodes and does not use a float to control the water level in the tank.
2. Adjust the float arm, the float cup or the metered fill valve.
3. Adjust the water level. Check the level of water in the tank, which should be a half an inch or less below the overflow tube (see diagram). Adjust the water level up or down accordingly, and flush to check that the level is balanced and roughly half an inch below the top of the overflow rube. Repeat until you get it right.
Even though I have made many repairs to plumbing fittings, I limit myself to repairs outside the walls. To repair joints, valves or drains inside the wall, I call a plumber to do the plumbing part and then make the wall repairs myself.
Many good plumbers will make every effort to save your walls, but sometimes a little destruction is needed to access the problem. In such cases, drywall repair is preferable to tile repair, because removing tile can require a whole new shopping experience. Sometimes, it’s best to access the problem from the other side of a tile wall, even if it destroys the wall in a bedroom or closet. You may even consider making the drywall opening into an access panel for later repairs, especially if it’s in a closet, under the countertop or inside a cabinet. In many homes, a tile wall backs up to an exterior brick wall, leaving no easy access. Some deck sub faucets and whirlpools don’t have access panels because they were built before recent code changes required them.
