Frequently Asked Questions

When you have a plumbing repair or upgrade, Crown Plumbing Service wants you to be fully knowledgeable of the service we are providing. We have designed this page to answer a few of the questions you may have. If we can assist you in any way, please contact us at 972-346-2332.



Why does my family always run out of hot water before everyone has showered?

Lack of hot water may have 2 causes. First, the dip tube that forces incoming water to the bottom of the water heater tank so that hot water can be drawn off the top may be broken. Or secondly, if you have an electric water heater, the lower heating element may not be operating properly. This would cause only half of the water to be heating up. In any case, the true reason for your lack of hot water can only be determined by an expert. Our professionals at Crown Plumbing Service will gladly be at your service.


Why do I hear a whistle sound in my plumbing system?

The biggest reason for the whistling sound you are hearing is because of high pressure within the lines. City code requires a pressure reducing valve on service lines with over 80 P.S.I.


When I consider replacing my sewer line what should I do first?

If you are considering replacing your sewer line, your first step should be a video line inspection. By using our inspection equipment, we are able to pinpoint the affected area(s), measure the depth, and view the accessibility of your sewer line.

Will I save money if I replace my 20 year old boiler?

Absolutely! Older boilers have a tendency to be less efficient. Old boilers are likely to be between 60 and 70% as efficient as a newer model boiler. A new boiler will also help you achieve efficiency ratings of over 90% and help you see a savings of over 30%.


What can I do about the white substance around my shower heads and faucets?

The white substance is calcium build up that comes from water that is too hard. A water softener installed by Crown Plumbing Service will eliminate the buildup problem and extend the life of your fixtures.


Is Crown Plumbing Service a qualified Grundfos water circulation system installer?

Absolutely! Each one of our technicians at Crown Plumbing Service have been expertly trained to install your Grundfos Comfort System.

How does a hot water recirculation pump work?

A hot water recirculation system is a continuous loop of slow-moving warm water that constantly circulates hot water through the pipes from the hot water heater to the furthest fixture. The water is always hot in the pipes and no water is wasted during the wait. As water begins to cool in the hot water line, the recirculation pump will then move the hot water from the heater throughout the pipe back to the hot water heater, creating a continual move of water that is instantly available for use with no waste.


Do you install tankless water heaters?

Absolutely! Crown Plumbing Service is proud to utilize the product excellence of Takagi. Because a tankless water heater provides an endless supply of hot water, a tankless water heater is becoming a premier choice among homeowners throughout the area. They also take up less space and are much more energy efficient than conventional water heaters.


Why does my garbage disposal get clogged so often?

Although garbage disposers have the ability to grind up many types of food, there are some which cause clogging because they can not be liquefied enough to pass through the drain trap and into the main sewer line. Items such as chicken skins, carrots, celery, and banana peels are too stringy and fibrous for the disposer to handle. At Crown Plumbing Service, we suggest that you put these types of items into the garbage instead. Also do not fill the disposer with a lot of vegetable peels all at once. Instead, begin by turning the water on first and then feed the peels gradually. This will reduce the possibility of clogging. Be sure to run cold water (not hot) down the drain for about 15 seconds after grinding is completed, this will also aid to flush the lines and prevent clogging.
