"Tried to rush three days of work into two days, didn't work. Still waiting for someone to return and seal the discharge pipes. Felt like they sent labor ready guys to do the job, I expected at least the foreman to be seasoned. Nevertheless the young men worked hard within their skill set. If you are thinking of outdoor gutter drains just get a landscaper to do it. Overall looking at the quality of the work, for the price I would of got the same service from a less expensive company."

"It was great. We just haven't done anything at all with it. The responsiveness of the guy was very good. I think it was just not quite what we were looking for. It wasn't that their price was really high. I think it was just the price that we decided. Instead of just redoing the whole thing. we decided to do a fraction of it. The quote was about $5000. Their professionalism is great. We just need the plumbing redone and then that little section re-tiled. I don't think they would do just a little bit. With ReBath, they do the whole system."

"Very professional. Jeromy wore a mask. He was polite and cleaned up the area after the install. I have a Choice Home Warranty and called them for the plumbing repairs. All i had to pay was a contractor service fee. In the future if i need a plumber i will ask for the Company OSP Plumbing in the Henderson/ Las Vegas Nevada area and ask for Jeromy."

Plumbing FAQs, answered by experts

Draining is the process of removing sediment buildup that has accumulated at the bottom of your hot water heater’s tank. Flushing is a more elaborate process that involves running fresh water through the tank to clean the inside thoroughly. You should at least drain your hot water heater once per year and flush it every other year—better yet, alternate between draining and flushing every six months.

When outside temperatures drop below 32 degrees Fahrenheit, your pipes are at risk of freezing. To prevent this, especially when you are away from home, set your thermostat to a range of 55 to 60 degrees to provide enough warmth. Maintaining this temperature can help you avoid costly water damage from burst pipes.

Knowing the signs can alert you to a clogged drain line. Clogs cause slow drainage or cause no drainage (if there’s a complete blockage). You may also notice foul odors, gurgling noises, water backing up in other appliances on the same line, or a poorly flushing toilet. If you experience any of these issues and think your line might be clogged, call a plumber.

Replacing a toilet typically takes two to four hours. Several factors can impact this timeline, including the condition of the old toilet, flange, flooring, and pipes. If a professional discovers issues like a cracked flange, damaged flooring, leaky pipes, or a broken wax ring, the installation will take longer. Additionally, some toilets, such as wall-mounted or in-wall-tank models, are more complex to install and may require cutting into and repairing drywall, which adds to the project time. Given the weight of toilets and the importance of proper placement, it is often best to hire a professional for the job.

Yes, you can water plants with water softened with potassium chloride. Potassium is a vital nutrient for plants, so using this type of water is harmless and can even be enriching. It is often a better option than water softened with sodium chloride, as too much sodium can build up in the soil and make it difficult for plants to absorb the water they need. If you notice that your plants are not tolerating the treated water, try letting it sit in a watering can for one to five days to allow the chlorine to diminish.
