"We had a stoppage in our patio drainage system near where several pipes meet. It wasn't clear exactly what the best avenue of attack would be. I suggested one opening which I thought was the straightest shot to the problem, but there was another the tech wanted to try first. That one seemed to lead to a T that couldn't be passed. The tech then used my original suggestion and that turned out to do the trick after some struggle with the blockage. There is usually an additional charge for going down more than one drain hole, but since success came with my original suggestion there was no additional charge which I thought was fair. In any event problem solved quickly and for the agreed upon price.
BTW, concerning the price, there is a rate sheet on their web page that lays it all out which I appreciate. There are 3 tiers: regular, overtime and double time which correspond to regular hours, off hours/weekends, and late hours/sunday/holidays. I had the work done on a Saturday morning so the indicated rate was overtime. However, there was a moment of confusion at the point of final payment when the office claimed it should be double time since it was Thanksgiving weekend. The rate sheet, original over the phone conversation and the quote from the tech on arrival all were for the overtime not the double time rate. To their credit, this was honored without too much fuss. The take away here is make sure you know which rate you are expected to pay especially when you are booking on or near a holiday. For example, is the Saturday of Easter weekend double time? It might be.
Anyway, great experience. I recommend The Drain Co.

"Our experience with the Drain Guys went very well. As with all service providers, the previous jobs they're scheduled for sometimes delays their next job which is what happened with us. But, once Eddie was on the job, he took care of the problem and us very well.

"The Friday before Thanksgiving we discovered large puddles in our laundry room and hallway. My dad, ever the handyman, tried to find the leak but grew distraught when he realized the water was coming from inside the walls and not our washing machine. That night, not wanting to chance my dad trying to fix it or worse, a friend of a friend, I became a member of Angie's list and looked for a reputable plumber nearby open on the weekends.
I called Saturday morning and they arrived same day Saturday afternoon (I told them it wasn't a major leak). They looked everywhere for the leak, moved our washer and dryer, opened up the wall, etc. They were able to isolate it to the hot water and advised us to leave the hot water off at night when the water pressure increased. Sunday they charge double, so we opted to continue on Monday. On Moday, first thing in the morning 8AM  they brought in a specialist with the fancy audio leak detection device seen on their website, which was kinda neat. A manager came by and told us there were a few other issues, but it turned out we just needed a new water heater (ours was over 10 years old, installed by my father and not up to code) and a pressure regulator. We were quoted a bit over 5k for everything, which was around how much we thought it was going to be, so that worked out. They came back on Tuesday at 8 AM and worked all day and restored hot water by 6. Thanksgiving was saved~! Hurray~! 
Service was excellent, everything was up to code. They taped down crate paper on the floors of the places they worked in, replaced the drywall, bolted everything into place, moved a bunch of heavy stuff without help--everything looked great when it was done. We're all pretty impressed and would use Richco again in the future.

This was a special order faucet from Delta purchased about 10 years ago.  I did not locate a model number and therefore, I need to replace the faucet.  Haven't had the money to replace it yet so I haven't called them back to do the work.  I may just have a new one installed by Lowe's since that is where I will purchase the new one.  Assume they will have the appropriate tool.
This provider was very prompt and responsive.  The original person couldn't come, so they called and explained and then sent someone else.
However, I was a bit dismayed that the plumber showed up without a tool that would take apart the faucet.  It was special order, but it's a standard Delta that is fairly commong these days.

FAQs for septic system installation and replacement projects in Los Angeles, CA

Most septic system replacements require several days to complete, not including permitting and preparation time. The process begins with site assessment and testing, followed by excavation, component installation, and final inspection. Weather conditions, property accessibility, and inspection schedules can all affect your project timeline. Your contractor can provide a more specific estimate based on your property's unique characteristics.

Standard homeowners' insurance policies don't cover septic system replacement due to age or normal deterioration. Coverage may apply if damage results from specific covered events, but routine maintenance and eventual replacement are generally considered homeowner responsibilities. Review your policy details or speak with your insurance agent to understand your specific coverage limitations.

Look for multiple indicators such as slow-draining fixtures, unusual gurgling sounds in plumbing, sewage odors inside or outside your home, or wet spots in your yard. Unusually lush grass over the drain field area, frequent backups, or recurring repair needs might signal system failure. Addressing these warning signs promptly can prevent property damage and health hazards.

DIY septic installation is not recommended and may violate local regulations. Professional installation ensures compliance with health codes, proper design for your specific site conditions, and appropriate safety measures. The specialized equipment, technical knowledge, and permitting requirements make this a job best left to licensed professionals who can guarantee the system's safety and effectiveness.

With proper maintenance, including regular pumping, a drain field lasts 20 years. Various factors influence system longevity, including household size, water usage patterns, and soil conditions. Regular professional inspections can help determine when replacement becomes necessary. If your system requires increasingly frequent repairs, replacement might be more economical than continuing to address individual problems.
