Do plumbers need to be certified?

• <div><p>Some states mandate that anyone doing plumbing work hold a plumber’s license, and some municipalities in other states require licensing, so it depends on where you live. However, hiring a certified plumber is usually best, even if it's a higher hourly cost and the license isn’t a state requirement. Certified plumbers are more likely to have the experience necessary to get your repair done properly, meaning a lower risk of issues occurring afterward. You also have some recourse if a certified plumber makes a mistake, as you can report them to the certifying authority.</p></div>

Q: How many water shut-off valves does a house have?

• <div><p>A house has two main water shut-off valves. One water valve location is inside the house. If your home is connected to a municipal water supply, you&rsquo;ll find it on the perimeter of the house on the side that faces the street. If your home uses well water, that valve could come in from any side. The other main valve is near where your property meets the street.</p></div>

Q: Is pipefitting harder than plumbing?

• <div><p>Pipefitting is a more specialized profession, and pipefitters work with complex systems and low- and high-pressure pipes, so it can be considered harder than plumbing. Though each profession comes with its challenges, the nature of pipefitting requires working with heavier materials in fast-paced and dangerous environments, which can be more challenging than working on residential and commercial plumbing systems.</p></div>

Q: Can you replace a standard toilet with an elongated toilet?

• <div><p>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&rsquo;t violate local building codes for clearance, which is the space between fixtures and walls. </p></div>

Q: What was the brown and black gunk in my shower drain?

• <div><p>If you've discovered a rather frightening buildup of brown and black gunk below your shower cover, you're not alone. The smelly sludge is often a collection of mildew and biofilm. Biofilm comes from the breakdown of soap scum, hair, skin cells, and bacteria that collects during shower time. It's quite common in a humid space and relatively easy to clean with a gentle DIY cleaning solution such as baking soda and vinegar.</p></div>

These people are scammers. Quoted $55k to replace the pipes in the house and insurance declined. Then quoted $18k to locate leak and repair by tearing up floors and walls. Insurance approved $12k and we were on the hook for $6k. They came out to detect the areas for the leak. The day they came...

They were prompt. Informative. Did what they came to do and in a businesslike manner. The installed product looks good and while it hasn't been used a whole lot, yet, due to weather conditions being pretty nice right now, seems to work very nicely.
