"there is a quick summary at the bottom if you want to skip the details. I have received service from this company twice. The first time I had a leak in a bathtub. They removed the drain with a Dremel since it was stuck, then they were about to leave to go to home depot to get plumber's putty, but I had some so they were able to get the part quickly replaced. Maybe this is a bit of a fluke, but that seems like a fairly basic thing to have when going to fix this kind of leak. Overall it was a positive interaction so I didn't think much of it. I recently bought a bidet on amazon. It arrived and I put it in. The problem was that I couldn't connect the toilet to the wall since the hose was a different size then the wall piece. The directions wanted me to remove the valve stem from the wall and replace it with their own. I called A Advanced because when it comes to plumbing, i would rather leave that to the professionals. I had called it a hose bibb because I just didn't know what it was called. someone called me back and asked me to explain in better detail what i needed done. I explained that the "hose bibb" needed to be replaced for me to connect my toilet and that I had the part to do it. from that conversation i received an estimate for $280.87. I was at work that day so couldn't be there, but my wife was there. The plumber that arrived worked for a while on the toilet, then went to home depot to find parts, then came back to the house and worked on it longer, then finally decided that it couldn't be done. We were charged $768.14 for nothing to get fixed. I called them to figure out what happened, I called near closing so they were not able to get a hold of anyone and it waited until the next week for me to talk to someone. I found out that the plumber never received the bag of parts, it was about 2 feet away in the sink. the same plumber came out and looked at it again, and went to home depot again. I was at work and managed to contact him while he was at home depot. I was told that the problem was with the thread depth and that there was no way to install this Chinese toilet without special ordering a part, and if I wanted him to keep working on it he was going to have to charge me more money. I declined. (Its not a Chinese toilet, the company that makes them is out of California.) At this point I was beyond frustrated. I left work early, drove home, went to home depot with the parts I needed to connect, and found a perfect fit within about 10 minutes of looking. I bought a Hex Bushing 3/4 in MIP x 1/2 in FIP for $7.75. I attached it to the included hose and then attached that to the valve stem. and everything worked. Home depot made it easy to find since both connectors were the same type. I just needed to find the appropriate brass adapter. the threads on the toilet hose are identical to the threads on a US water heater. I called A Advanced back and presented my evidence. I was asked what it would take to make this right. I asked for some of my money back. I can understand getting charged for the plumber going out to my house without a full understanding of what is going on. but at no point did he ever tell my wife that he was going way over the estimate. this is the exact response i got back. "I spoke with my COO and my foreman due to the amount of time we spent on the project we are unable to provide any sort of refund. I understand that is not something you want to hear but that is our decision." _____________________________________________ to summarize: - every time this company has come out to my house they have needed to go to Home Depot during the visit. - I was charged nearly 3 times the estimate with no work done and no warning that the bill was piling up. - the plumber was never able to install the toilet despite multiple trips to home depot - I installed the toilet with a $7 adapter i found at home depot in about 10 minutes. (I am not a plumber) - The company chose to not refund me anything If a plumbing company needs to go to home depot every time they do a house call, that is a company that is not prepared at best, and a scam company at worst."

"My elderly mother is partially blind and disabled. On November 1, 2021 her washing machine broke leaking water in her home. In desperation she called rotor rooter. Roto rooter came out, stopped the leak, and put dryers in and left. They returned a few days later to remove the dryers. The technician quoted my mother a cost of about $3000.00. My mother signed a contract but could not see what she was signing. After Roto rooter Reno removed the dryers they sent a bill to my mother for $9000.00. The contract she signed stated Roto rooter would remove walls, roofing, insulation, baseboard, tile etc. Roto rooter didn’t do any of those things. Roto rooter is price gauging and took advantage of an elderly disabled woman. Roto rooter technicians were in the home no more than 3 hours total. First my mother did not have capacity to enter into a contract as she couldn’t see what she was signing. 2 Roto rooters technicians told her the cost would be about $3000.00. 3 Roto rooter did not do the work in the contract. I believe Roto rooter is commuting elder abuse and fraud."

"ORGINIAL POST: DO NOT USE THIS COMPANY!!! After spending over $2,000 on pumping, inspection and camera work, I had one simple request- WAIT 30 DAYS BEFORE SUBMITTING FINDINGS TO THE COUNTY! We were trying to work the problem. I called TWICE about this and was told both times, no problem, we will wait. They submitted it this morning. Because they did not respect my wishes to wait, I now have to pay over $20,000 through the county when we had a plan in place to avoid that and get it fixed independently. Go with a company that follows instructions, not absolutely ruins your life. Thanks for the 10 year debt I will now have due to your negligence. My realtor and contractor will be referring all other agents and all clients elsewhere, and notifying them all of this unprofessional behavior. EDIT: Here's how I would have expected Serena, the office manager I spoke to today to enter the conversation: yes, you're absolutely right, we did breach agreement, how can we make it right? Here's what happened: per her: "there was a human error that was not our fault. The result would have been the same no matter what" (no it would not have and she has no way of knowing that). "I have you on record asking not to submit it at all" (I told her yes I did say that, then asked what's the extension period, and we're getting off track). "Here's the history of your septic system" again no, we're getting off track. You admitted three times in this conversation you breached our verbal contract. You say the results would have been the same no matter what, but that's absolute garbage- no way she'd know that. If you truly have nothing to hide, and know you messed up (which you admitted to) send me the phone recordings I requested not respond "we will be happy to do that upon getting subpoenaed.""

Septic Tanks questions, answered by experts

Most homeowners know there’s a septic system problem when they can smell one. However, this isn’t exactly a scientific deduction method. Consider some of the other signs: standing water or constantly damp earth in the drainage area, toilets and sinks that won’t drain or frequently back up, and loud plumbing. You really need to be on top of routine maintenance with septic systems in order to avoid such unpleasant symptoms of a septic issue. 

A septic tank should be emptied approximately once every three to five years, though this frequency will vary depending on your water usage, the size of your tank, how many people are in your home, and other factors. A maintenance plan for your septic system may be useful for professional emptying and inspection of other important parts.

While homeowners connected to a municipal sewer line still have to keep up with plumbing maintenance, the downside to a septic system is that all the maintenance falls on the homeowners. Not calling in a pro to pump the tank every few years or accidentally flushing or draining the wrong types of materials can quickly cause clogs, which can back up into drains around the home.

There are three layers of wastewater in a septic tank: scum (solid waste that floats to the top of the wastewater), liquid (the relatively clean liquid wastewater in between the two other layers), and sludge (solid waste that falls to the bottom of the wastewater). The buildup of sludge is one of the main reasons septic tanks need to be pumped. If the tank is more than 1/3 of the way full with a combination of sludge and scum, it’s time to call a pro for pumping.

It only takes a few days for a septic tank to fill with water after a pro has pumped it. This is completely normal, and the water is a vital part of your septic system’s wastewater treatment process. The water that fills your tank days after pumping is not the same as the tank being filled with waste. You shouldn’t have to pump your septic system more than once every three to five years unless you have a tank that’s too small for your home’s water output or there’s a problem with your leach field.
