Arrow Plumbing has kept up with those demands with additional training needed to be current with those changes.

"Effectively paid $2200 per hour to fix 3 gas leaks in the line. Re-swabbed 2 couplings with glue and replaced 1 elbow coupling. Decide for yourself if that is expensive or not before calling."

Water Softeners questions, answered by experts

Because it’s been through the water cycle, evaporating and becoming slightly acidic thanks to dissolved carbon dioxide in the atmosphere, rainwater tends to be naturally soft compared to groundwater, which has just been in contact with limestone. However, the natural hardness level of water always depends on where you are and other factors.

Yes, a water softener can remove scale deposits. According to the U.S. Department of Energy, after you add a water softener to your home, “gradually the softer water will dissolve limescale scale deposits and remove the problem entirely.” Installing a water softener—or water descaler—will also help prevent new scale deposits from forming.

There are many possibilities for why your shower’s water pressure is low. It might be a simple-to-fix issue like the water valves being partially turned off, a dirty showerhead or hose, leaks in the plumbing, or an old showerhead. However, low water pressure in the shower could also indicate a larger issue with your home’s plumbing system.

Some shower water softeners are effective, but this isn’t always the case. Most shower filters only filter out chlorine, not hard minerals like calcium. Other shower filters can't handle the demand in homes with very hard water. It's also important to change the filters on your shower filters. Failure to regularly swap out old filters will make the filter ineffective over time. 

Water softener installation costs vary, but on average, homeowners will pay between $200 and $6,000. Due to their location, complexity, type of unit, and water demands, water softeners have a very wide price range. That being said, the average installation cost for most homes is around $1,500.
