Jumping into a major plumbing project without the right know-how can result in personal injury, major property damage and tens of thousands of dollars in repairs. If you run across any of the following problems, it’s time to call a plumber.

The cause of dribbling sinks and showers isn’t always easy to pinpoint. Pipe obstructions, city supply issues, and poor pipe design can all play a part in low-pressure fixtures. A plumbing professional will be able to recognize the source of your problem and provide an appropriate solution. Attempting to DIY a low-pressure problem can damage your home and sewer lines, as well as result in a continued low flow.

No hot water is usually the result of a failed water heater. Water heater defects can stem from a variety of issues, ranging from total breakdowns to minor component defects. Regardless of the source of your water heater’s failure, it’s a good idea to hire a plumber or technician to handle the job. Water heaters operate using electrical and gas systems. Mistakes in working with these devices can result in personal injury and damage to your home.

Severe, regular backups are common signs of a blocked sewer line. These clogs are normally caused by tree roots, sediment buildup or non-flushable items affecting your sewer line. Attempting to clear your blockage by using chemicals or rodding machines can damage your sewer lines and cost you thousands to repair. A pro will have the experience and skill necessary to identify the source of your problem and provide a safe solution. This is especially important in the case of a broken or punctured sewer line. Attempting a DIY repair on a broken sewer line can expose your home and property to raw sewage, as well as incur thousands of dollars in damage to your neighborhood’s sewer lines.

Burst pipes usually occur in the wintertime when frozen water in the line expands and causes the pipe to break. Cracked pipes can cause major flooding and incur thousands of dollars in water damage. Additionally, affected pipes can be difficult to locate. Damage can occur in your yard, below your foundation or behind your walls. A plumber will be able to pinpoint the source of your leak and begin the water abatement process immediately. Searching for the source of your leak, even after you’ve turned off your main, will give water additional time to seep into vulnerable parts of your home. A professional plumber will also be able to recommend repairs in the case of damaged flooring, drywall or foundation.

Installing major appliances or fixtures will require the expertise of a plumber. Attempting an involved plumbing project without the proper knowledge and experience can result in expensive repairs, and sometimes entire re-installations. It’s especially important to enlist the help of a plumber during remodels and renovations. Many large overhauls include updated room layouts. In bathrooms and kitchens, this means moving appliances and fixtures. Relocating items like sinks and dishwashers will require moving supply lines and the necessary drains. Attempting these updates on your own can result in a ruined renovation and extremely expensive repairs.
