"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 !"

Plumbing questions, answered by experts

Worn-out rubber washers or O-rings are some of the most common causes of a leaky tub faucet. These small rubber parts create watertight seals within the faucet. However, they can deteriorate over time because of mineral deposits and water pressure. If you have a cartridge-style faucet, a cracked or damaged cartridge can also be the culprit. Regular use of the handles wears down these faucet parts, and they eventually start allowing water to seep through and create a drip.

Replacing a standard toilet with an elongated one is straightforward. The two types can be installed using the same existing drainpipe and plumbing. If you have a small bathroom, make sure that an elongated toilet doesn’t violate local building codes for clearance, which is the space between fixtures and walls. 

The toilet flange anchors to the subfloor, usually with wood screws or cement screws, but most of it should sit above floor level at full height. When a flange is flush with the subfloor or below it, it can lead to the creation of leak paths.

No, a larger well pressure tank will not increase or improve water pressure on its own. The pressure control on the well pump is what determines the water pressure in your home. However, a larger tank does offer other benefits. It can hold more water, allowing you to run it for longer before the pump needs to turn on. Because the pump cycles on and off less frequently, there is less stress and wear on the well system. This can lead to a longer lifespan for the pump and tank, and you may experience fewer pump-related issues that could affect your water pressure in the long run.

If you want to increase your water pressure, you can try one of the following solutions:

• Adjust the tank’s pressure settings to a higher PSI (pounds per square inch).

• Replace your current pump with one that has a higher flow rate (GPM).

• Install a water pressure booster pump in your plumbing system.

• For pressure fluctuations, consider replacing your current setup with a constant pressure system.

You can use a stud finder or wall scanner to detect plumbing behind a wall. A stud finder can help detect metal plumbing pipes. Or, you can use a wall scanner, a special tool that many pros use to detect pipes when water is running. Make sure a faucet is on nearby to get the water flowing before you fire up the wall scanner.
