Had my lawn sprinkler valve replaced. Called in the morning and the technician was here in early afternoon. Chris replaced and tested the new valve within 1 hour. Great service and quality work. Company name is deceiving and they do many other kinds of repair work besides plumbing. Give them a call and you'll be surprised what they can do.

I had a great experience with Diamond Head Plumbing. They fixed 2 different problems. One was a corroded gas pipe which had to be dug up and replaced and the other involved replacing plumbing in the shower. Neither job was simple and the shower work involved renovation as well as plumbing. Warren and Jesse worked hard and did a great job. Will definitely use them again.

I really do not recommend this company at all. Like the review by James L. and others are saying, I concur that they were unprofessional, arrogant and rude. Plus they have this outrageous pricing system where the customer pays a flat rate for ""EACH service"" such as drain cleaning would be one set charge no matter how small or close to the drain the clog was, and no matter how little time it took, and an additional added flat rate if they use a camera, and then added on top of that, a labor rate per hour. Seemed like triple pricing for such a small job. Then when I questioned how much it was for each of these potential services and how much for the hourly rate, they couldn't answer my question. He went on, either you agree to pay whatever we charge or find another plumber. I said, ""I do not think we have a meeting of the mind on this job. I am afraid I will be given an enormous bill for a small job."" He went on, ""This is the way we run our business and if you don't agree, don't use us. Seemed to me they were attempting to make a small, maybe 1-2 hour job into a big, double or triple unreasonably priced job. And, most importantly, my attempts to reconcile my fears were met with rudeness, hostility and what seemed to me to be unprofessionalism. Read the reviews; others saying the same thing.

Incompetent , arrogant, rude , unprofessional, untrustworthy and expensive($140.00/hr) to fix irrigation system. Technician blamed everyone but himself "" I've been doing this for 40 yrs"" Did not honor warranty on repair done a few weeks prior; charged me again and wanted to do more expensive / unnecessary work which I declined then had the nerve to tell me that he didn't like me going around his back when my plumber repaired it @ a fraction of the cost /time .They want to make big jobs out of little ones. Should have read previous yelp reviews before I used them. In response to Diamond Head Plumbing's rebuttal: 1) the area that was repaired by Diamond Head Plumbing was work that they completed with ""new thicker pvc ""it cracked after 2 uses @ the joint where I can see the new piping sku number. The 2nd crack occurred where a root perforated the piping that they claimed was new . Got photos where they just cut around root and not remove it so further damage can occur at a later date. 2) DHP wants to claim that my plumber who built my house voided the warranty for installing 2 water pressure regulators; the plumber did not touch any irrigation lines because he doesn't need to; everything was above ground and they do not do sprinklers anyway. I contracted DHP to fix my irrigation not touch my plumbing. I ALSO NEVER ASKED FOR A REFUND and paid all my bills because I wasted enough time /frustration with this company. 3)my irrigation is 14 yrs old; if water pressure was an issue it would have burst pipes yrs ago; normal wear and tear is to be expected so stop using water pressure as an excuse. 4) technician could not diagnose the problem and wanted to come back for more additional appts/ expense while being unprofessional. 4) for every critical review on yelp, DHP tries to do damage control and shift the blame to the customer instead of acknowledging their mistakes . This is another example of their arrogance and refusal to admit their mistakes.

Incompetent, rude, and totally unprofessional. They came out to the house to camera scope the sewer line; they removed the toilet inside the home to do so when they couldn't find a sewer clean out at the back of the house. Since this is unusual to do I let them know it was fine to do so as long as they left the home in the condition it was. Tyler the tech responded to me saying not to worry he's a professional. Once they removed the toilet and tried to secure it back down, they told me that the bolt has broken and its because the flange that was used was an incorrect part for that toilet. They said that they will not turn the water back on for the toilet since it may leak. I asked them to repair what they broke but now say they can't do so because it wasn't to code and they would happily repair it at MY COST. I told Tyler that this was wrong and before they came into the house the toilet worked with out leaking and no broken parts. He started getting excited and started to raise his voice at me, at which point I told him he should not speak to me that way. He told me in a huff that he couldn't ""do"" this anymore and to call his office to speak to his boss. I asked him for his boss's name and number and he told me to google them. He finally gave me their main office number and I called to speak to Mariella, her response wasn't better at all; during my conversation with her explaining what had happened, she cut me off and said he already told me mam, and you're not listening to us. The toilet is not to code so we are not able to put it back. I told her that it wasn't broken before they touched it, the toilet has been in use without any issues as it was for many years before they decided to remove it. The line went silent and after several minutes of hello? are you there? can you hear me? I realized that they had hung up on me. I called them back and they had switched their phone lines to say that they were now closed.... who does that? Completely rude and unprofessional. How do they declare that they are ""professionals"" and act like that?

Ridiculous pricing. 7k to install two gas operated dryers and one washer? Never call these people. 7k for 2 days of work hardly seems fair or reasonable. Got two other quotes for free. Both less than 1k. Ridiculous. Never call here people. Save your time. Just call someone else

5 star review for these guys... the last Plummer's I called did not fix the problem.... it's hard to find a good plumber in Honolulu. These guys were honest, fair and did the job right. That's all I ask... it took three plumbers to finally do the job right. The other 2 Plummer's I called had 5 star reviews on yelp and they were rip off artists. The marketing was good but the results-bad. They wanted to Charge me twice as much as diamond head plumbing..Super thankful for Diamond Head plumbing.

Just finished renovating my Moms bathroom, Joel (Vice-President) Diamond Plumbing & Bath said it was going to take 9 days to complete a full restoration, shower was a Fudo style tub, change sink, toilet, flooring, add recessed lights and change the window! Job took 15 days to complete, workers took out a large sheet of copper from old shower, Mom told workers we will keep the large sheet of copper, however someone took the sheet of copper and probably sold it for extra cash! Sad because subcontractors for Diamond Head Plumbing & Bath do come in whenever they feel like working! Some of them are good workers, others just give them a bad name, wouldn't hire these folks again! Lol
