"Exchanged messages with Mike to describe work needed, replace an outdoor faucet and shutoff value (previous faucet was leaking). He gave an estimate, reviewed work to be done. Replaced outdoor spigot with a frost-proof spigot, put on new value. Quick test and validation. Professional, efficient and happy with work done! Thank you Mike !"

"The plumber showed up on time, was pleasant and because it was snowing he took the time to cover his shoes. We had a leak in our shower/tub combo that 2 other professionals were unable to fix. He spent about an hour and a half located the problem and it hasn't leaked since."

Plumbing questions, answered by experts

DIY is not recommended for commercial settings due to safety and code compliance. Hire licensed professionals.

Flushing the toilet only to realize it’s clogged can cause anxiety. To avoid a clogged toilet, use less toilet paper. If you notice that the toilet is flushing and refilling slower than usual, you can use a plunger to clear clogs in the S-trap. If that doesn’t work, call a plumber to check your system and possibly clear the drain lines.

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.

In most cases, it’s better to repair a toilet than to replace it. Fixing issues like low water levels, running water, and flushing problems is less expensive than buying a new unit. Start thinking about replacement if the toilet is cracked, using excessive amounts of water, or is over 15 years old. Newer models are more water-efficient and clog less often than older models.

If you notice smells or clogs, you’ll know something’s wrong with your shower drain P-trap or the plumbing. Most of the time, smells and clogs are due to a clogged P-trap. However, in some instances, you may smell sewage. If this happens, open your windows and contact a plumber to help. They can do a plumbing inspection and let you know if anything needs to be repaired or replaced. Common culprits are a dry drain, cracks in the plumbing, or a clogged vent.
