"John was Great!!! Our first appointment had to be cancelled due to unforeseen circumstances, but John communicated the issue immediately which was much appreciated, and set new appointment. When John came arrived on time (A+) Professional and listened to my idea/suggestion (A+) Did the job in less than the estimated time (A+) Cleaned and REPAIRED the wall area which I didn't expect (A+) Price was 1/3 of what others wanted to charge. Definitely, recommend NorCal Water Treatment to others, and will be rehiring for future plumbing projects/issues. I'm real BIG on customer service/professionalism and John is "The Man!""

"Oak called 2nd but came next day/ UN-prepared to do either repair or water test (requested on phone) or even replace with ready new ADA toilet that the lying receptionist booker said they have “some in stock and if not he will show a catalog of choices”. Guy came punctually with Nzo tools or appliances Or knowledge of what I asked for as an “URGENT repair/replace”. See ABC review same call. Not quite as bad as them doing same since we also still have broken HVAC too, both said they would fix ( I bought gasket already, they could have put in) or replace if they brought new toilet. Problem is not in water pipes except they need testing for lead - both said they would do this too - when I asked oak re taking a sample, how long sitting in pipes? He wiped off his soda water bottle and asked “which pipes?” !!"

"Wow! After a few "no-show" plumbers, I found a gem amidst the storm - literally! My sewer ejection pump stopped working and Ramiro was my hero! We were able to coordinate over the phone with me describing my situation and sending a few pictures. Ruben showed up this morning and was probably one of the nicest, kindest, more competent people I have had work on my house ever. He was able to restore my pump to working order and replace the parts needed. Ruben was very communicative and precise in his diagnosis and repair. He left after a few hours with my pump back up and running - the pump was cleaned out and the alarm float replaced. I am so relieved and more importantly, happy to know whom to call if one of my 4 pumps is in need of some TLC at any time. You would be lucky if you needed help with your pumps to have Quality Pump Service be able to help you!"

"Very professional. Resolved our issue in a timely manner. Only complaint is that a part was replaced without talking to me about it ahead of time. It wasn’t a cheap part. After the work was done and I was given an explanation I would have most likely done the work. But I would have liked the option to make that call."

Water Softeners questions, answered by experts

A lower-end water softener would cost around $900, not including installation. Each home has different requirements, water hardness, and number of inhabitants, so there’s a huge range in pricing—$600 to over $6,000. The average water softener repair bill is around $500, meaning it’s a much better option to repair any issues and only replace your softener if absolutely necessary. 

Yes. Hard water is what causes scale buildup, and a whole-house filter provides numerous benefits beyond water softening. Any water that enters your home will go through the filter, which cleans up all water that you will use for cooking, bathing, and drinking. A whole-house water filter also blocks harmful particles like heavy metals.

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.

Yes. To get soft water, you can install a water softening system, which will replace the calcium and magnesium ions in the water with sodium or potassium ions. Water softeners cost anywhere from $200 to $6,000, depending on the size and complexity of the system. You can either install a water softener for the whole house or just at your shower heads. If you’re sensitive to sodium or potassium, you can install a salt-free water conditioner.

No, hard water isn’t dangerous. The added calcium in hard water can contribute to good bone health. However, it can also cause dry skin and hair. If you have dry skin or hair, consider using a water-softening system to help minimize the minerals in your water. Plus, these systems can also add some sodium to your diet.
