"I tried to replace our old Moen faucets myself, but was unable to remove the old ones. Rudy responded quickly after I first called him and he came to see what I needed. Initially, he was unable to remove the old faucets due to the type of faucets we had and limited space under the sinks. He came later with his assistant, but they were unable to install standard faucets with mounting nuts from below the sink given the limited space. It took a couple of weeks to find a faucet with bracket and screws instead. Once Rudy found these, he and his assistant came and installed them in about an hour-and-a-half. The new (Delta) faucets were more expensive than the ones I had originally bought at Home Depot, but were of better quality."

"I have used Reiko plumbing many times in the past.  I was very satisfied with all aspects of their work. The labor charge was $75/hour. 
In the last month they offered to change my garbage disposal for $778.42.  There would not breakdown the cost of labor and replacement parts.  I went to Home Depot and brought a top of the line InSinkErator for $223.00.  I replaced the garbage disposal unit myself in 30 minutes.
I think it unprofessional to not divulge the cost of the replacement parts and their labor costs are unjustified.

"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.

Wells and Pumps FAQs, answered by experts

If you have a self-cleaning washing machine but you’re still seeing lint, your water pump filter might be clogged. To clean it, you should unscrew the drain hose, then remove the water pump filter. From there, you can inspect it and clean it with warm water before replacing it. Check to be sure your washing machine is functioning by running a short cycle. 

Having a well means that a household’s water supply, including water that comes through faucets, showerheads, and appliances, is supplied through a private source rather than from a city. The well pulls fresh water from an underground water supply, such as an aquifer, and the well pump pushes the water from the well to your household.

How do you set your well’s pressure tank? All you need to do is first drain the tank of water and find the pressure switch. Remove the switch cover and adjust the switch with a wrench—clockwise to increase water pressure, and counter-clockwise to reduce it. Each complete turn of the nut on the switch should equal 2.5 psi. Once this is done, replace the switch cover. All that’s left is to adjust the pressure of the tank itself using an air compressor and a tire gauge to support the new setting.

Yes, professionals can upgrade your well pump system, enhancing its efficiency and reliability. They evaluate current systems to recommend suitable upgrades, ensuring proper installation that optimizes water access and meets household demands.

No, a larger well pressure tank will not increase or improve water pressure on its own. The pressure control on the well pump is what determines the water pressure in your home. However, a larger tank does offer other benefits. It can hold more water, allowing you to run it for longer before the pump needs to turn on. Because the pump cycles on and off less frequently, there is less stress and wear on the well system. This can lead to a longer lifespan for the pump and tank, and you may experience fewer pump-related issues that could affect your water pressure in the long run.

If you want to increase your water pressure, you can try one of the following solutions:

• Adjust the tank’s pressure settings to a higher PSI (pounds per square inch).

• Replace your current pump with one that has a higher flow rate (GPM).

• Install a water pressure booster pump in your plumbing system.

• For pressure fluctuations, consider replacing your current setup with a constant pressure system.
