"Adam is by far the best plumber I’ve had do work in my home. We have done a number of remodeling and repairs throughout the year and he’s the best. Here’s why: very knowledgeable about plumbing issues; found the best solutions for our project and he studied the best way to install and did excellent work. We had a Halo 5 water softener and filter system and on demand hot water recirculating system installed. We now have great tasting water out of the tap, no more greasy feel in the shower and no more waiting for hot water and waste of water waiting for it to get hot. Both systems work great."

"He was prompt and very polite. He did a good job, was fast and cleaned up after himself. He did several jobs for us in about a half a day. We really appreciated his help. He repaired holes in the wall of the water heater closet that had been cut out because of a leak. He repaired the sink drain and the faucet. He also took out two raised flowerbeds in the front yard and repaired a third one. He rebuilt one box. He also hauled away all the old wood."

Plumbing FAQs, answered by experts

A back pressure valve is a control valve used on production vessels, such as separators, treaters, and free water knockouts. The valve holds pressure until a set point is reached, and then releases upstream pressure to reset. Back pressure valves are not safety mechanisms. Instead, they are regulators designed to keep the fluid, gas, or liquid mixture in a system at a certain pressure level to prevent bursts and other incidents.

Meanwhile, a backflow preventer is a safety mechanism that kicks in when the pressure has already failed and contaminated water flows in the reverse direction. Most backflow preventers consist of two one-way valves, or check valves assembled together. This design only allows water to pass through in one direction but not the other.

Besides opting for a professional inspection, there are some other telltale signs that a pipe in your home is ready to go. Keep an eye out for signs of leaks and spot-check exposed areas of piping. Musty smells, spots on your walls, and dripping sounds are signs an unseen pipe has a leak, for example. You can also check the tubing for stains, flaking, and discoloration, all of which are signs of corrosion.

You can use PEX pipe underground, and it will hold up well in underground insulations. Keep in mind that PEX tubing is not rated for outdoor use and that insulation is necessary in regions that experience cold winters. When using it underground, you should also bury PEX piping at least 12 inches below the frost line.

The lifespan of bathroom pipes is between 20 and 100 years. This is a wide range, so to narrow it down, it helps to know which type of material your pipes are made from. Copper and cast iron have the longest lifespan—between 50 and 100 years—while other materials, such as galvanized steel and brass, last for 50 years or less.

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.
