Check your toilets, make sure they are not leaking. Then check to make sure your fill valve, inside the tank, is not overflowing through the overflow pipe. The last thing you can check is your flapper. You can do this by adding a couple of drops of some food coloring to your tank water. Let it sit for about 15-20 minutes and check to see if the water in your bowl has changed color. If it has, you will need to replace your flapper.

If it is dripping from the spout, replacing the seats and springs or the ball valve could be all you need to do. If it is dripping from the supply lines underneath, a tightening of the fittings might solve the problem. If it is dripping from underneath the faucet itself, you may have to replace it. 

If you have checked your water sources the next step would be to check your meter box and make sure there is no water leak there. After that, you check your water heater to make sure the overflow pan is not holding water. If it is, then either your tank or your relief valve is leaking. Also look over your yard and see if there are any dark green spots where the grass is richer and too moist. If you find a spot like that, you may have a leak on your main water line.

The most common is a small chip or hole in your tank cover that is allowing air to pass through at a high rate of speed. This causes a whistle noise. It could also be caused by your fill valve. A simple adjustment would stop the noise.

This is a normal sound when your water heater is re-filling after having used hot water. If you hear this when you do not have any water sources running and should call a plumber.

This is usually caused by a worn-out or faulty hammer arrestor. A simple replacement of the hammer arrestor will stop the banging noise.

If you hear water running inside your walls and there is no water sources turned on, you may have a leak from one of the water pipes. 

If you are having trouble with just one sink draining, you probably have a stoppage in the immediate drain line. These can be removed by using a drain snake to clear the line. If it is further down the line, you might not be able to reach it with a regular drain snake. If the water is draining slowly, you might have what is referred to as a partial stoppage, which is allowing some water to pass through at a much slower speed. Check the pop-up to make sure there aren’t any obstructions like hair in the line. If there are no obstructions, you can try using a drain cleaner to remove the debris in the line.

If you have low water pressure where you once had good water pressure, there could be several possibilities. The first thing you should check is the supply line. You should make sure it is turned all the way on. Another reason is the aerators are clogged. Unscrew the aerator from the faucet head and clean out the sediment that may have collected by soaking it in vinegar overnight. Then with an old toothbrush, just brush out the buildup. advice.

The first thing you should check is the main water shutoff valve and make sure it is fully in the on position. The shutoff is located in your garage but can be different depending on where you live. If the main shutoff valve is completely turned on but you still don't have water, check to make sure there are no breaks in your main water line. If there are, call your plumber. If you are experiencing no water flow at only one faucet, then first check to make sure the supply line is turned on. Most likely you have one of two types of shutoff valves: a "twist turn" to open and close the valve or a "push-pull." If your supply lines are in the "on" position and you still don't have any water flow, check to make sure there is no sediment buildup in the aerator. If there is, removing the sediment should restore water flow. If you still do not have water flow, then you should call your plumber.

You can try using a handful of ice cubes along with some lemon peels in the disposal and let it run for about 30 seconds. Then squirt a little bit of liquid dish detergent into the disposal while it is still running. Let the cold water run for another 30 seconds to wash away any remaining debris.

Your plumbing system is designed to block out sewer odors by way of the P-traps that are attached to fixtures. These traps contain water, which seals out the smell but if if the water evaporates, then the odors are allowed into the home. To solve this, take a bucket full of water and pour it into each of the drains where you are experiencing an odor. If it is a shower or sink that you do not use often, you may want to make this a part of your regular cleaning routine to prevent any future odor issues.

In 1994, a law was introduced by the federal government to regulate that new toilets were to use no more than 1.6 gallons of water per flush. The first models that were introduced were cause for complaint, so the manufacturers developed new flushing technology and enlarged internal passageways, resulting in a properly functioning toilet. There is a toilet known as a power flush commode which uses a pressurized tank to produce a surge of water that enters and clears the bowl of any waste. Although they are not as quiet, they work well and are like commercial toilets.

You may have a partial stoppage somewhere in the drain line. This could also mean your septic tank is full and needs to be drained. However, if this is a common occurrence, then you might want to consider having a plumber run a sewer camera through your drain line to check for obstructions, a possible break in the line, or root growth in your drain line.
