My tankless water heater was discharging water randomly. I had no idea what the issue was. But Sergio came by ASAP and helped diagnosed what could be the issue. It was determined that my water pressure regulator was broken and the water pressure was 140 psi. He replaced it with a new one the same day within an hour, and lowered the pressure to 50 psi, and no more water is discharging from my water heater anymore.Read review on Google

HOME & BUSINESS / SERVICE GUIDE
Residential Plumbing For Your Home
Supply pipes, drains, fixtures, and hot-water equipment affect one another. A symptom in one room can originate elsewhere, so we begin with what changed and inspect the relevant part of the system before recommending work. When you call from Altadena, tell us what’s affected and when you first noticed it.
Residential Plumbing Customer Reviews
I called Sergio with Best Quality plumbing at 2 PM he asked for pictures of the piping / ball valve leaking. He gave me a fair price, was at my house on 20 min and fixed the issue using Brass Ball Valve. I am an engineer and can tell you his work was really good and his charge was very reasonable. I will certainly recommend him. After, the first experience I called Sergio again for replacement of our main line. His price was 10% lower than other two I had called. I had a plumbing engineer write the specifications and showed to to Sergio and his response “ no problem “. He and his crew dug one clean out 3’ deep, removed the turf 58.5’ away dug 8’ used the best commercially available piping and fitting and finished in less than 2 days. Checked the turf, and saw a few kinks, called Sergio and Carlis showed up on Labor Day, fixed it to perfection. I can’t ask for better job done professionally. Thank you Sergio and the team. I would certainly recommend youRead review on Google
Best in Santa Clarita. Sergio was very responsive and came out quick multiple times when we had plumbing issues. He fixed the leaks and was able to change out the parts. Good pricingRead review on Google
LOCAL NOTES / ALTADENA
Residential Plumbing In Altadena:
What’s Local.
Public facts about Altadena that affect residential plumbing — each one links to its official source.
Age Of Local Homes
The median home in Altadena was built in 1946, according to the US Census. In homes of this age, original supply and drain piping may be near the end of its service life, so we check the pipe material before recommending a repair or a repipe.

Altadena gets its water from one of several local water companies — Lincoln Avenue Water Company, Rubio Cañon Land & Water Association, Las Flores Water Company or Kinneloa Irrigation District. Its latest water quality report shows Rubio Cañon groundwater averaged 380 mg/L and Lincoln Avenue groundwater 220 ppm as calcium carbonate in the latest reports — very hard on the USGS scale.

LA County Public Works states that sewer laterals are entirely owned by the private property owner they serve, including the section under the public right of way (County Code 20.24.080).

In the Eaton Fire area, existing septic systems can be reused under conditions, but a property within 200 feet of a public sewer must connect when it expands or when its septic system fails.

Common Plumbing Problems At Home
Choose the closest issue to organize the details. You do not need to know which plumbing service to request.
Locate The First Visible Clue.
Tell us where water appears, whether it is spreading, and which fixtures were recently used. A stain may not sit directly below a concealed source.
Keep away from wet areas near electrical equipment and call if water is active.
List The Affected Fixtures.
Note whether one sink is slow or several fixtures change together. A wider pattern can point to a shared line rather than one fixture.
If wastewater is returning, stop using affected plumbing and call.
Describe The Use Pattern.
Tell us whether hot water runs short, changes temperature, or leaks near the heater. Mention which fixtures run at once without opening equipment.
Do not adjust gas or electrical controls.
Define The Fixtures And Timing.
Share the rooms, fixtures, and project sequence involved. Existing valves, supply, and drain connections can affect what the work includes.
A project estimate can begin with the scope and a few photos of accessible areas.
