"⭐⭐⭐⭐⭐ Water Heater SOS was a lifesaver! When our water heater broke down, they responded quickly, diagnosed the issue, and had it fixed the same day. The technician was professional, knowledgeable, and took the time to explain everything clearly. Pricing was fair, and the service was top-notch. I highly recommend Water Heater SOS for anyone needing fast, reliable water heater repairs!"

"Both the main and secondary condensate drains were clogged and the service technician cleared them.  He also cleaned filters and verified proper operation of all equipment.  We intend to use Carini for future annual checkups and needed service.

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.

"The original technician that was sent to do the job did his best but after a series of issues and 2 days of attempting to remedy them I concluded that he was in over his head.  In his defense, this type of sensor faucet is pretty new on the market and he had limited experience with this particular kind of installation.
I ended up contacting the company owner, Bob Muller.  He listened to my concerns and he took immediate action to resolve them by offering to finish the job himself.   Bob arrived within an hour of our conversation to do the work and within another hour he had the faucet working perfectly. He also checked the work that had been done on the toilets to make sure that everything was done correctly.  I'm a stickler for doing things right and up to code and Bob was on the same page with me.  It's not easy to find a really good plumber.  Bob has earned my future business.

"Repaired my leaking filtration system, gave it a tune-up, corrected the back-flush setting which was wasting water/money, and said I'd get another 7 years out of it. Very happy I didn't have to replace it."

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.

The main difference between a water softener and a water filter is what they remove from the water. A water softener is specifically designed to remove hard minerals, while a filter removes a wider range of contaminants above a certain size, such as bacteria and other impurities. If your primary goal is to remove minerals, a softener is the best choice. If you want to remove various contaminants for safety or taste, a filter is more suitable. Filters are also typically less expensive to install. Depending on your water supply's specific issues, you may need to install both systems for comprehensive treatment.

It depends on the type of surface. For instance, if you’re trying to get rid of hard water deposits on glass, you can spray vinegar onto the surface and wipe it off with a soft cloth or non-abrasive sponge. However, if the deposits are on granite or natural stone, it’s better to use baking soda and water rather than vinegar or other acidic cleaners.

A tankless water heater should be at least 10 feet away from a water softener, although the pros you hire for water softener installation can help you determine the correct distance. These two units need to have some distance between them to prevent hot water from the tankless water heater from flowing backward into the water softener when it runs a regeneration cycle.

If your water softener repair is fairly straightforward, like a simple filter replacement, then you can probably do it yourself with little risk. However, anything beyond a simple fix should be addressed by someone with extensive plumbing expertise to avoid costly water softener problems, like leaks. 

That said, even simple problems can be complicated to diagnose, particularly if your water softener is attached to a whole-house treatment system. So, unless you feel absolutely certain that the problem is an easy fix that you can take on yourself, it's probably best to hire a plumber to diagnose and fix the problem.
