Commonly Asked Plumbing Questions and Answers

What should the temperature of my water heater be set at?
The factory setting for your water heater is typically 120°F. If you have an older model, you can set the thermostat at medium. Gas models usually have a dial on the front of the gas valve. Electric models have thermostats that are behind the two panels on the side of the tank. The temperature can be adjusted to meet your needs. Keep in mind that hot water also helps in minimizing the growth of bacteria.
Caution: Turn off the electricity to the water heater before performing any personal maintenance. Exposed wires behind the panels may result in extreme shock
Why is a rumbling sound coming from the water heater?
Rumbling sounds can be an indication of sediment built up on the bottom of the water heater. Water trapped in this sediment can begin to boil. The sediment does not allow the heat to transfer to the water in the tank. You can drain a few gallons of water from the bottom of the water heater tank by attaching a drain hose to the valve at the bottom of the tank. Allow it to drain for about five minutes. Most newer models have a feature that prohibits the buildup of sediment in the tank. If your heater is an older model, it may be cost-effective to replace the water heater. Contact Mr. Dan’s Plumbing if you determine your water heater needs to be serviced or replaced. 
Caution: Discharge the water into a floor drain, laundry tub or bathtub. Hot water will kill your grass and will also crack a toilet bowl if discharged into the toilet. Turn off power to water heater prior to draining.
What happens when roots get inside the drain lines?
Roots from shrubs and trees will completely fill a pipe with multiple hairlike root masses at each point of entry. Root masses become clogged with toilet tissue, grease and other debris flowing from your home, resulting in reduced flow, slow running drains and in most cases a complete blockage. Once roots have entered the pipe, they continue to grow and expand. This increased pressure often breaks the pipe and may result in total collapse, which requires repair or replacement. Clay tile pipe is easily penetrated and damaged by tree roots. Concrete pipe and PVC pipe may allow root intrusion, but at a slower rate than clay pipe. PVC pipe has fewer joints and the tightly fitted joints are less likely to leak. Call a Mr. Dan’s Plumbing to unclog or repair your drain.
What is the buildup around my shower head and faucet?
​To remove these mineral deposits from the showerhead, take off the shower head or remove the face plate and soak it in vinegar overnight. In the morning use an old toothbrush to gently scrub off the deposits. Mr. Dan’s Plumbing professionals can explain to you all about the water softening and conditioning options available to you.
How do I eliminate the foul odor coming from my garbage disposal?
To eliminate odors, place ice cubes and lemon peels or orange peels in the disposal, and run for 30 seconds. Finally, run cold water for about 30 seconds with a little dish detergent to rinse all the debris away.
What is the recommendation for replacing a fixture in my home?
We recommend that you choose a fixture made by one of the major manufacturers. If cracks are present in the tank of a toilet or bowl of a sink, this can affect the operation of the fixture. Improper mounting and deteriorating seals can affect the operation as well. Many of the new toilets conform to new standards that require they use no more than 1.6 gallons per flush. If you are replacing an older model, this may take getting used to.
What could be the cause of my high water bills?
Check to see if a toilet is leaking. Check to see if water is overflowing into the overflow pipe. This pipe is in the middle of the tank which has a small tube connected to it. If water is running into the overflow pipe, adjust the fill valve to stop the flow approximately one inch below the top of the overflow tube. Periodic maintenance by our plumbing professionals will ensure proper operation.
The plumbing in my house makes groaning and knocking noises.
​You could have lost your “air cushion.” Turn the water supply off at the main valve. Turn on all the faucets in and around your home. Then turn on the main valve again, and then shut off each faucet. This should take care of the problem. If this doesn’t work, please call our plumbing professionals.
My kitchen drains are partially clogged because the sink drains slowly. What should I do?
First, use a plunger. Second, you can remove the trap and remove any debris. There is also the third option, calling one of Mr. Dan’s Plumbing drain techs to run an auger and remove the debris.

Caution: Liquid drain openers are dangerous to your health and the health of the environment. They can burn your skin and ruin your fixtures.
I have a major water leak! What should I do?
It happens. Water pipes burst, sometimes violently, and water begins spewing all over the wall and floor. Don’t panic! Look beneath the fixture for the water shutoff valves. There is a cold water shutoff valve and a hot water shutoff valve. Turn the handles clockwise until the water stops pouring out of the water supply line. Sometimes water shutoff valves freeze up from lack of use. Don’t force it all at once or it could break and cause bigger plumbing problems. If the valve spins freely and won’t turn the inner seat, tighten the set screw on the face and try again. For a main water line leak, turn off the water to your home by turning the cutoff handle for your main incoming water line vertical to the water pipe. If your home is not equipped with a personal main line cutoff, you can cut it off by the street. Once your water is cut off, call Mr. Dan’s Plumbing.
