"The tech was professional and arrived on time.  The general routine cleaning went fine.  However, the troubleshooting did not resolve the issue. He did notice the unit leaning a bit and straightened it out, but a couple of months later during another hot spell the unit was leaking again.  I called them and they sent the field manager who cut and replaced a very crooked condensate line and it appeared all was resolved.  Fast forward 10 months of rare usage: after 3 days in a hot spell - the leak reappeared.  I shut off the a/c and waited for a good 5 months before calling a different plumber who blasted out the main condensate and the secondary line, and tested it by running a gallon of water through the line.  I don't believe the line was sufficiently cleared if at all, the first two visits with Carini. This seems like a pretty routine issue with condensate lines so I'm disappointed that it would have been either overlooked or insufficiently cleared out.

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.
Using a snake we can go through the cleanouts on the side of the house.
With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

Water Softeners FAQs, answered by experts

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.

While not everyone can detect taste differences in high-calcium water, water that has a slightly metallic taste probably has too much calcium.

You can install a water softener system by turning off the water supply, draining the water, and then connecting your device to the waterline. Next, you’ll fill your tank with the recommended amount of salt or brine (whichever your unit calls for; be sure to read the instructions). Turn the water supply on and check for leaks. You can opt to let your water run for a few minutes, then test it using strips. 

The process of inspecting your water softener system is similar.

Whether you need a license or permit for water softener installation depends on your location. Some municipalities require the installer to hold a plumbing license, while others may only require a permit and an inspection. In some cases, both a permit and a licensed installer are necessary, and some areas have no requirements at all. Often, only certified plumbers and electricians are allowed to pull the necessary permits. To find out the specific regulations in your area, you can contact your local building department. Alternatively, a local water softener installer or plumber will be familiar with the requirements and can typically pull the permits for you. Regardless of local laws, it is always recommended to hire a licensed professional to ensure the system is sized and installed correctly. You can use tools like Angi’s state licensing tool to verify an installer's license status.

There are several things that can shorten the life of a water softener. Homes with very hard water may have to replace the unit sooner because the water softener works harder to filter out the hard minerals. High water usage and infrequent maintenance can also put more strain on a water softener.
