Recommended Customer Reviews

Aven, the owner at Magnum Plumbing is dependable and knowledgeable. We called Magnum Plumbing when we had an emergency leak in one of the condos that we manage. We had a quick response. They came over, stopped the leak and then corrected the issue. Since the unit was vacant, I was concerned about turning water back on. Aven came over on the holiday weekend and made sure all was good. He cares about his customers. Pricing was fair and I would recommend him for any plumbing job. He is Zteam's plumber going forward.

Unfortunately only one star on this review. When he came the first time he needed just one more part for the toilet but had to order it. Aven said when he would come it would be on him , no charge and now I see why. I had to call him to see if he remembered. We did set up an appt around his schedule. He said he'd come between 8-10 and texted at 8:50 he was sick so, we reschedule. He was suppose to come at 8 this morning but canceled because his babysitter ""flaked"". I thought maybe he would reschedule for this week but that was a big fat NO. He texted me and said,"" see what your schedule looks like and will work out something"". Weather it be my schedule or his schedule there is obviously no worries about coming back. In fact his text to me was, "" Your toilet is working. This is not an emergency. This is a free service"". Evidently free puts you on the back burner. Aven wants to resolve this but it's to late. He gets a zero this time around and I will never use him again!

Magnum Plumbing was so awesome! He came right out and fixed my problems. Aven will be our plumber for now on! Thank you Tons from Illusions Hair Studio!!

These guys were awesome. Aven Was very professional and responded extremely quickly. We had a faulty faucet which he replaced and did so on very short notice. Pricing was very competitive and I would definitely go back to these guys no matter what. 6 stars

Very pleased with Aven's work. He was responsive and professional. We had a clogged shower that was due to corroded pipes underneath. I got several quotes since this was a big job and Aven won with a fair price and good communication / professionalism. I will call him again for help with my San Diego rental units.

Aven is awesome. Called him on a Friday afternoon at 4:45 answered my call and was at the house Saturday morning to take care of my emergency.
Great guy extremely knowledgable and very reasonable on price.
Highly recommend.

I reached out to Magnum Plumbing to get some help with a broken sink valve. Aven reached back out to me quickly with a very reasonable estimate, and was available to come to the house early the next day to get started. When he showed up, he was on time, friendly and very professional. He did a thorough and quick job of fixing the broken sink valve, stuck to his initial estimate price, and was happy to let me pick his brain on some unrelated plumbing issues we have been having. I will be sure to reach back out to Magnum Plumbing with any future plumbing projects!

so i want to to thank you for being so professional because we need plumbers like you in san diego.

This plumbing company was hired to ""clean up"" some issues that our contractor's guys couldn't figure out. Aven showed up right on time, was thorough, personable and took care of all of our outstanding plumbing concerns. I would highly recommend them!

What a great company, customer service A+. I called for a repair on a high end toilet and explained that Dad was handicapped and needed a repair ASAP. When they got here they were knowledgeable with the Toto system. I will be using their service from now on. I highly recommend this company, also very professional.
