"I was on the fence in replacing my water heater. I decided to get some quotes from plumbers. I came across Reliable Plumbing. I read their customer reviews, which were highly favorable. Then I spoke to Jerry. Which was like talking to an old friend. Jerry's honesty and professionalism won me over. Paul the plumber came 2 days later, did a great job. Paul was professional. Pollite and explained everything to me. I was extremely happy with the price, the service and the honesty. I will be using Reliable Plumbing going forward"

"I can't find the words to adequately state just how satisfied we were with this significant job. From start to finish John and his crew, Paul and Mike, were absolutely fantastic. They listened to all our concerns and went above and beyond what was called for. During the installation an exterior water pipe was hit that was unknown to us as well as John. John stopped the installation and fixed the broken pipe that was now leaking in the basement. This clearly was not his fault or his responsibility and I was more than pleased to not have to call a plumber! Obviously damage to landscape with this type of work is to be expected, however when all was complete it was clear that John minimized the upheaval to our yard. I would HIGHLY recommend John to anyone in need of a new cesspool system. My only regret is that John's buisness is limited to cesspools as he is the type of individual and buisnessman I would love to use for all of my home repairs!

Plumbing FAQs, answered by experts

Whether you hire a plumber to replace an outdoor spigot depends on how handy and confident you are with your DIY capabilities. Local plumbers will be familiar with your area’s plumbing codes, and while replacing a spigot looks simple, it can be a deceptively complex task. Ultimately, hiring a professional will ensure you get the job done right the first time and avoid any problems down the road.

If you have to hold the toilet handle (also called the toilet lever) down to flush, you probably have a chain problem. A chain that cannot fully lift the flapper will close too early and not clear the toilet bowl. Try adjusting the chain length so there’s about ½ inch of slack.   

When outside temperatures drop below 32 degrees Fahrenheit, your pipes are at risk of freezing. To prevent this, set your thermostat to no lower than 55 degrees. For added safety, especially when you are away from home, maintaining a temperature between 55 and 60 degrees will provide enough warmth to keep pipes from freezing and help you avoid expensive water damage from burst pipes.

You can tell if a pipe is leaking behind your wall if you see bubbling, warping, water stains, mildew, or mold on the ceiling, flooring, or walls. Musty smells can also indicate a leaky pipe. Finding a leaky pipe in a wall can be challenging, so work with a pro to pinpoint the leak’s exact location.

You can find out what type of shower valve you have by checking the manufacturer’s name and the valve’s serial number or model number. That information should be located on the back of the shower trim. You can use the name and number to do a quick online search to figure out which type of shower valve you have.
