Tank full above output pipe that leads to leach field, only 30 days after partial repair.

DO NOT RECOMMEND We hired Diamond House Plumbing located in Riverside in Aug 2023 to install a leach field for our septic system, and it has never worked properly since day one. Despite multiple repair attempts, the system continues to fail, with water returning to the tank instead of reaching the leach field. When I requested proof that the system was functioning (such as a visual inspection) one of the owners Joshua Miller, refused. Instead of standing by his work, he denied responsibility and ignored our concerns. I filed a bond claim due to their failure to provide a working system, but the company falsely claimed the job was complete-even though it wasn't. The bond adjuster confirmed they were required to provide a two year warranty, yet Diamond House Plumbing failed to do so. If you are considering this company and their finance company Foundation Finance for a major plumbing job, beware. In our experience, they do not honor their obligations, avoid accountability, and refuse to provide proof ad will falsely proof of proper repairs. I would never recommend this company to anyone looking for a reliable and ethical plumbing service.

The ugly water filtration system that isn't even plugged in

We had a burst pipe in our backyard while we were out of town. Josh Owner of Diamond House plumbing came out and said, that we needed to repipe the entire inside and outside of our home. Otherwise he could fix the pipe but the next weak pipe would burst down the road. I asked how much this would cost. He quoted me $38,925.00 I asked if they had financing, because we couldn't afford to do it otherwise. He asked if we could pay 50% up front and I again said no. Without finance we could only afford to fix the one pipe. He took my information for to see if I qualified for a loan. I explained that my husband had some health issues and missed some payments because of it. Even though he was all caught up his credit suffered a good score. I said that my credit was pretty good, however my husband was the one bringing in the income. Josh placed me on a long hold and would he came back on the line he told me I had been approved for 100% of the loan with monthly payments of $570.00. The loan documents were sent to me and I signed everything. I told Josh that we were getting on a cruise ship the next day and that I would be unreachable for one week. I left him both our adult children's phone number in the event they needed to speak to anyone. ( they never tried to call either of our adult Children). About 3 days into our cruise I got an email that they needed to add my husband to the loan, because he was the one who made the money. I told the receptionist that my phone wouldn't be able to call out until the next day when I got to port. I phone them the next day and she said they would only do the loan if my husband was added. I again explained that his credit was less then good and she said that okay they just needed him on there for proof of income. We never heard anything from them for the rest of the trip, so we just assumed everything was good When we got home I found our very clean house now covered in a very thick Sheetrock dust and our air conditioner no longer would come on. Two days later Josh came to our house and said that we weren't approved for the loan. They had continued working knowing there wasn't a loan in place even though I told Josh before they ever started the only way we could do this was if we had 100% financing. I wasn't happy that they hadn't waited to do the work until they could reach me. Our house has been left in shambles holes everywhere which Josh told me before they started in his exact words they would take care of all the drywall. I have exposed copper pipes running up the back side of my house. They charged over $4k for an ugly exposed water filtration system that's not even plugged in. When I asked Josh about this, he said they could run an Extention cord. We have zero water now to our front lawn and mature ficus tress my gardeners said they disconnected those lines when repiping. Josh said every pipe would be replaced inside and out. Now my lawn and tress are going to die. The shattered a double sink marble vanity several outlets no longer work in our house including some bathrooms. Josh has been trying to strong arm us for medians payment. I again explained they should have done the job until they could have spoken to me about not having a loan. He said they will not fix any of the damage done to our house until they have 50% we have tried to get a credit line, but are having trouble. We paid they $2090.00 dollars this month that was all that we could swing. $90 was a credit card surcharge which is illegal in California. We are planning of making payments each month until we can find a loan. We feel very tricked, conned, scammed into doing a job that we told them up front we couldn't afford with lout getting finance. They should have stopped work immediately when the loan didn't go through. That in itself should be illegal. On top of the stress of my husband's illness we now have this financial hardship added to our stress. That should have never happened. Don't trust this company they are shady.

Got a Groupon offer for $37 for $100 of services to use with Diamond House Plumbing. My toilet flapper was leaking water and the flushmaster arm seemed to have a hard time filling up the toilet. I didn't know how to buy the parts so I thought I'd use this Groupon which was the perfect option. I called Diamond House set up an appointment, which went well, they were on time, and did the inspection on various things in our house, that took 15 minutes. Then they went out to their truck to make the estimate which took 30 minutes. At this point we called the company to ask what they were doing that was taking so long. So they came back in and told us that we had 2 Options: 1. Approximately $600 to replace the whole toilet. 2. Approximately $500 for parts and labor. Which we could not afford either one of those offers so we declined. That very next weekend it just so happened that my brother in law was in town. He looked at the toilet and saw that the flapper was warped and the flushmaster needed to be replaced. So he went to Home Depot picked up the parts that was less than $20 and took him 15 minutes to fix. My brother in law is not a plumber he is a cable man haha but as you can see this company will rip you off.

Zack did an excellent job fixing our leaky faucet. He was very professional and tried his best to get us a discount. Thank you Zack!

Justin and Carlos just left our condo.. They delivered top notch assistance in snaking our kitchen…read moredrain. Our disposal and both kitchen sinks had been backed up for a few days with slow drainage.. I did everything I thought I could to get the drains unclogged, Liquid Plummer, Boiling Water, Vinegar and Baking Soda mixture repeated over several days but nothing worked! I called Righty Tighty this afternoon based on their Yelp reviews and their office set up an appointment for me right away.. Justin had called to introduce himself and advised he'd be arriving in an hour. He and his associate arrived as promised, asked a few questions, checked the sink and gave us his expert opinion. He was up front in the pricing, did not have to upsell anything and was very efficient. Plumbing issues are usually always a dreaded nightmare for people who know nothing about pipes and plumbing etc.. I was skeptical to even pick a plumbing company because stereotypically you hear discouraging things. At any rate, We are beyond pleased with today's service and with this company!! The line was snaked, Justin kept us involved by showing us the clogged areas with the mini camera and advised what he was doing and going to do. We will call them in the future if we ever have any other plumbing issues come up, fingers crossed, nothing in the near future. Thank you for being professional, polite and very helpful!! A+++++

What could improve was some type of assurance not a guarantee, but assurance that the job they do…read morewill last more than four days. Is that unreasonable? I don't think so however, they don't offer a "guarantee", so that the charge that you pay for them to snake your outside drain the first time is exactly that the first time. They want to know you for 375 each and every subsequent visit. I have two words for them one begins with an F the other one begins with a U. They didn't seem to have super high intellect, but I bet you they can guess what it is. They're con men, rather con Cowboys If the service doesn't work in three or four days, they'll come back out but you have to repay the service so you have to pay $375 twice. That's just their policy. Every time I would voice a complaint the one cowboy would say I hear you ma'am. I'm glad he heard me, however, he did absolutely nothing to remedy: ie, help with looking into alternatives, call a supervisor, scratch his ass, other than say "I hear ya ma'am" pleasant enough, however after the sixth time - worthless - makes you angry in fact. It's like "well get back on your horses boys and head back to Texas and take your ugly ass machine with you" Ready, tidy plumbing con artists they want to nail you for a service call no matter if it's an hour after your service or two hours or a day, two days, three days, four days, It's just their policy. The charge is 375. If you call them every day of the week it's every day is $375. Horseshit horseshit horseshit horseshit horseshit horseshit.
