Contact us today, we'd love to make you a satisfied customer too.

"Great to work with. They were efficient and knowledgeable. They took care of the rebate for our heat pump. Only thing lacking was responsiveness to email/phone communication after the install was done. Heat pump system is working great."

"Everyone that we dealt with couldn?t have been nicer. We had a tub to shower conversion which was completed in one day. Matt, the installer, laid a tarp down from the door to our bathroom to protect the floors. He asked for our input when he was installing the shelves and grab bars. After he finished cleaning everything up he explained how to used the new shower head and what to use to clean the surface. The next day we texted him with a question and he immediately answered. We couldn?t be happier with the job done and the professionalism of the company."

"The salesman was knowledgeable, professional and explained everything about the shower install well. I gave him a deposit of $3200. I did not hear from anyone so after 3 days I called but no one returned my call. Called back again a week later to cancel the order. Left a long message stating I did not want to cancel the order but was concerned because no one returned my calls. Finally, received a call from a regional manager. He connected me to a local manager who set up an install date a week later. The installers were polite and professional. Gave me some helpful advise. Job was completed in less than a day. The shower door came a week later. I have had the shower for over a month. It is beautiful. I love it. Quality work. I would highly recommend Premier Home Pros."

Plumbing Heating Companies questions, answered by experts

While you don’t have to run out and immediately buy a new toilet at the first sign of a clog, if the toilet keeps clogging because it’s a low-flow or poorly designed model, a new toilet may be the way to go. If your toilet keeps clogging, you can try using less toilet paper, adjusting the fill valve, checking the toilet vent pipe on the roof, and using a toilet auger to make sure nothing is stuck in the pipe or trap.

Yes. There are a variety of standard pipe sizes used in plumbing. The main supply line connecting your home to the street is either 3/4 or 1 inch in diameter. Supply lines are 3/4 inch in diameter. Individual components are 1/2 inch in diameter. Meanwhile, your main drainpipe is often 4 inches wide. Most shower and bathtub drains are 2 inches in diameter, most toilet drains are 3 inches in diameter, and most sink drainpipes are 1 1/4 or 1 ½ inches in diameter.

Freeze-proof faucets can still benefit from insulation, and they will need covers if you live somewhere with extremely cold winter temperatures. These faucets work with a design that keeps excess water in the pipes inside the home to minimize the risk of freezing, plus a downward slope for any water flowing through the pipes to keep moving. But keeping a cover on all faucets, even freeze-proof fixtures, is the best way to avoid frozen and burst pipes.

White vinegar or baking soda can remove the crusty white deposits that minerals leave behind. A paper towel soaked in vinegar and wrapped around your faucet can effectively dissolve scale, but can be corrosive to some materials like brushed nickel if left on too long. For materials that can’t withstand vinegar, a paste of baking soda and water applied with a toothbrush can gently scrub away scale deposits.

No, you can’t drain your sump pump into your home’s sewer system. In fact, it’s against the law in many places because dumping extra water into a municipal water system can disrupt or overwhelm the treatment process. And for similar reasons, you shouldn’t discharge a sump pump into your septic system, either.
