Salt-Free Water Conditioner System Sales, Installation, & Maintenance, Diamond Bar, CA

A great alternative to salt-based, self-regenerating water softeners is a salt-free water conditioning system. Salt-free water conditioners are not only better for the environment, but they are also highly effective at producing better-tasting, softer water. They’re also compact, easy to maintain (only requiring a quick swap of the cartridge once every 6-12 months), and affordable (typically, 50-80% less than salt-based systems). Plus, for some Inland Valley residents, they may be the only water softening option since many cities have begun banning salt-based water softeners. Call us today for a free consultation. We are a factory authorized dealer for nuvoH2O, and are also qualified to install reverse osmosis water filtering systems in Diamond Bar homes and businesses.

Drain Cleaning/Snaking, Hydro Jetting, & RootX Chemical Treatment, Diamond Bar, CA

Signs of an obstructed drain include slow draining sinks or faucets, poorly flushing toilets, odors coming up from your drains, and sewage backups. In kitchens, a clogged drain can result from grease and soap buildup, food, paper towels, and other obstructions. In bathrooms, we’ve removed feminine hygiene products, flushable wipes, rags, sponges, toys, cell phones, and even keys. And in sewer lines, it is usually tree roots. For small obstructions, snaking is usually sufficient. For pipes that have extensive gunk build up, hydro jetting is the best option. In other cases, a camera inspection will help us determine what exactly is causing the stoppage and where is the problem located. If it looks like there is a problem with tree roots, we can treat the drain with RootX to remove tree roots and prevent further intrusion. Contact us today for drain cleaning, hydro jetting or RootX treatments in Diamond Bar.

Sink and Faucet Repair, Sales, Installation & Replacement, Diamond Bar, CA

Steve’s Five Star Service offers Diamond Bar’s best value in faucet and sink sales, installation, replacement, and repairs. Common repairs include removing clogs, fixing leaks, and re-caulking. If the sink or faucet damage is irreparable, we can replace them using the same product or one very similar within a very short timeframe--usually within the same day. We also do new sink and faucet installations and replacements if you are looking to upgrade your bathroom or kitchen in Diamond Bar.

Polite And Considerate

Steve's Plumbing was recommended by a friend who had a great experience with them. We called them out because we had slab leak on the back patio. They came out promptly, had the leak detector guy find the exact location of the leak, and did the repairs the next day. Martin Brody was the technician who handled the repairs. He quoted us a fair price, showed up on time, finished the job as promised and cleaned up everything. And he was polite and considerate. We plan to have them out again in a few months for another plumbing job.

Martin has been to my home twice. Each time he arrives with a smile, yet professional. He does great work. Replace vanity and toilet. Gave me a fair price. I will continue to use Martin as my fix it plumber. Thank you for your quality work.

Slab Leak Detection, Diamond Bar, CA

Water line leaks can occur nearly anywhere. When they occur behind a wall, above the ceiling, in an attic, or around a property’s exterior, the signs of a leak are hard to miss, making the source of the leak fairly obvious. However, when the leak is under an asphalt or concrete slab, then the first sign of a leak will be an extremely high water bill. When this happens, it helps to use slab leak detection technology to pinpoint the source of the leak. By knowing exactly where the pipe has cracked, we can help you determine the best way to fix the pipe. We can either tear up the concrete, repair/replace the pipe, and then refill and patch the hole, or we can reroute the water line, which is generally less invasive. If you think you have a water leak under your home or business, call Diamond Bar’s experts in slab leak detection, Steve’s Five Star Service.
