"Two service Techs, Daniel and Kevin, came by the same day i called regarding a clogged sewer line. They were very pleasant and personable which put me immediately at ease. They performed an inspection and showed me a live video feed of my sewer line, indicating where the roots were growing in that caused the clogging. 
They recommended hydrojetting due to the size of sewer, and scheduled a visit the following day.  The next day the same techs came by and cleaned out the sewer line via hydrojetting. Afterwards they did another video inspection and showed me their results. They were professional, communicative, clean, and very pleasant to deal with.

"We had 2 jobs done by Iwai. First, they did the central air for our 3 bedroom house in LA. Many of the other companies said we needed to put in additional vents but Iwai suggested putting the system in and adding the vents later if we were not satisfied with the air flow. This ended up saving us thousands. the second jod was a mini-split HVAC for our garage conversion. our general contractor gave us a ridiculous price so we called our friends at Iwai for a second opinion and they were great. The price was low and when the inspector gave us a hard time about silly details Brandon sent his team out multiple times to deal with it even though it was a relatively small job for them. Both times the work was high quality, the price was great and the professionalism was above reproach. I would recommend them without hesitation to anyone."

Wells and Pumps FAQs, answered by experts

Consider replacement if the pump is over 10 years old or has recurring, costly issues.

Here are some signs of a bad well pump that a pro should look at: 

  • If your well pump isn’t pumping water, you could have a leak or malfunctioning pump on your hands. 

  • If your water pump runs nonstop, there might be a leak or problem with the pressure tank, which can cause the pump to fail. 

  • Low water pressure can happen because of your pressure tank, low-water levels, or a wrong-sized pump. 

  • Dirt or sediment in your water can be a problem with a powerful pump, damaged pump filter, or the pump’s location.

Schedule annual inspections, monitor water pressure, and address minor issues promptly to avoid major repairs.

If your well pump gets stuck in its casing, you may be able to free it loose by gently wiggling the line or by vibrations from tapping the line with a hammer. However, if your pump is stuck in a buildup of minerals around the casing, you’ll probably have to call in a well pump contractor to get it out. They’ll likely use a muriatic acid solution—a strong, corrosive acid—to break down the minerals and free the pump loose. 

To avoid a stuck pump in the future, experts recommend a professional well cleaning once every 10 years. 

Some states and municipalities restrict well pump repair and replacement to licensed plumbers and technicians, while others don’t have requirements. However, it’s always a good idea to hire a certified plumber to repair or replace well pumps and water pumps. Certified professionals are far more likely to get the job done correctly and prevent future issues, which is especially important for ensuring access to clean water for your home.
