I was looking for a seat and spring combo for my leaking shower head handle. It is an off brand design and no company markings can be seen anywhere on the unit. Every store that I went to did not have it but most of all, none of the others offered much help, if any. But DAVE at Security Plumbing went above and beyond to try and help me out. Not only did he try to match up different parts that he had in stock, but once that wasn't working he was happy to talk to his suppliers and other store locations to try and get the correct part. Although we were unsuccessful at finding it, the amount of effort this store and their employees went trough to find my $2.99 part was unparalleled. I will definitely be returning for other plumbing needs or questions. read more

This was by far the worst customer service I've ever experienced and it was the second time! Their inventory is dog shit and their employees are rude as fuck. Do not waste your time coming here, they move slow and act as if they're doing you a favor. Bottom line, fuck these guys. read more

I purchased a P69 pilot generator (1950-001) and gas valves (710-502) for our apartment unit wall heater from Security Plumbing in mid-October 2025. Our handyman installed the parts shortly afterward. Unfortunately, since the installation, the heater has continued to malfunction, and I have already had to call a technician multiple times just to temporarily get it working. As of 5/28/26, the heater stopped working again, and now I have to replace the same parts once more. I returned to Security Plumbing with my receipt, and an employee named Ran provided me with the manufacturer's information for Robertshaw along with their phone number (800-304-6563). When I contacted the company, the representative stated that they were unfamiliar with Security Plumbing and could not assist me. I then went back to the store and spoke with Ran again, who advised me to contact Steve at the store. After several phone calls, I was finally able to speak with Steve, but unfortunately he was very rude and disrespectful during the conversation. I am very disappointed with both the quality of the parts and the level of customer service I received. I expected more professionalism and support, especially after experiencing ongoing issues with recently purchased products. read more

They do have a wide selection of stock items and they manage the back stock behind the counter which can be helpful to fine that item you're looking for, but prices here are high and they won't tell you pricing over the phone. The two times I've called ahead they are "too busy" to tell prices. Drove to this shop both times to get in-person pricing. When on-site they quoted prices that were almost double Anawalt and Home Depot. I'm a big supporter of small businesses but this one seems to just not do customer service very well. read more

Working on a job nearby I stopped by to purchase some materials both guys had very bad attitude and poor customer service. They didn't have what I was looking for and gave me attitude when I asked them. Take your business elsewhere. read more

Have to drop a recommendation to this company. The service was exemplary. The staff, so knowledgeable and welcoming! They have everything you could possibly need under one roof! Check them out for sure!! read more

Ron and the team are very helpful . Found exactly what I needed I will definitely be coming back for my plumbing needs. Great group

Swung by without adequate prep, planning, or info. Dave was patient, helpful, and went way above and beyond for me, despite my unpreparedness. Five stars. read more

Life savers! Short version: they had a hard to find part that I needed immediately. Got me in, gave great service, and a great price. Long version: Our less than a year old European faucet started leaking HORRIBLY sending water pouring out from underneath the sink. Huge mess. A plumber came out, identified the hose as the problem but cautioned a replacement part might be hard to find. He recommended this store. I called, they said some on down, and then Dave the store Manager spent time looking through all their stock to find the best replacement. He was so kind and upbeat and positive which meant a lot because I was just imagining being without a useable kitchen sink for weeks while waiting for a part to be shipped- with 2 small kids at home in the middle of a pandemic. The part worked and Dave is basically a super hero who prevented me from doing more damage to our wood floors by leaving puddles of tears everywhere. Dave- Thanks so much! Will call you first for all our plumbing needs!! read more

I just picked up an item for my 20+ year old faucet not sold in any hardware stores in west or downtown LA. I almost gave up and replaced it but I had sentimental reasons for wanting to keep it. These guys are legit and no nonsense. Very helpful and professional. Tbh, I don't think they give a rat's ass what reviewers think of them here including my review but if you treat them with respect they always give it back. These guys and the buisness is awesome. I highly recommend them. I got better service here than anawalt, Ace or Home Depot. read more

After visiting 4 other stores around town, I stopped by Security Plumbing and they found new faucet handles to replace my obsolete ones, that worked beautifully for me! Dave was super patient and explained exactly how I was to replace the handles myself and gave me a little lesson on how that faucet system actually works. (Now who actually does that!...Thank you Dave! ) Superior Plumbing & Heating Supply is a great find, family owned and operated, pride of ownership! What a gem of a place! read more

This is by far one of the worst retail experiences ever! They guy with the hat at the check stand was rude! Would not give me a receipt even paying in cash and then decided to give my money back when I suggested it was probably a scam. Wow. Go elsewhere! read more

Good old guys sitting around who could answer your questions thru experiences. Don't call. You have to go down in person. Speak face to face and they can solve your problem. I know from experience. Well rounded plumbers. Keep up the good work. read more

Love these guys! Very helpful staff! Saved me when I was in a pinch at work, they carried a very obscure part most shops would not normally carry. Thanks again, I will be back! read more

This would have been a one star review if they had not stayed open a couple extra minutes to let me in, which I appreciated. My experience was overall horrible. I made the mistake of not taking a photo of what I needed thinking I remembered what it looked like. To me, an honest mistake, but to them justification to be verbally abusive, condescending, and downright patronizing. read more

Stopped by here to ask a question and a seal for a hose. The gentleman here was nice and helped me out. He gave me the seal for free and I was on my way. Good karma points. Thank you. read more

Great store with very helpful people! They have everything you need in stock, and they provide good advice! Very reliable and honest! They also give good referrals. I went there to buy the parts to repair a leaky pipe which I could not get at home depot! They had everything and their advice was spot on! Don't be fooled by the shabby look of the store from outside. It's worth a trip. read more

Went in looking for 2 feet of abs piping. They would sell me nothing less than 10 ft. I bought it thinking I had no choice, but my next stop at Orchard Hardware to buy more fittings (which the people at Security could not help with), OHS not only cuts pipes but had shorter leftover pieces you could buy as needed. I went back to Securtiy 15 minutes later to return the 10 foot 4-inch abs and he, the owner, would not take it back. Said they would not be in business if they did. Btw, OHS is still in business and they offered returns on everything. I told the owner at Security to keep the abs 10 foot pipe without giving me a refund as I did not want to throw it away and if he felt morally okay about reselling it, go ahead. I told him it wasn't about the $23, it was the waste. He was okay with it!! Hope he's happy. read more

I own a 1932 house in Rancho Park with 3 baths. One of the baths has original pedestal sink and tub. Keeping them from dripping is often a challenge because of the worn stems and seats. Although this shop is geared for professional plumbers and contractors, they are always helpful to the DIY guy (yours truly), with only the occasional jibe but otherwise helpful attitude! Much nicer than the miserable know-it-alls at Snyder Diamond. read more

I was looking for a replacement stem for the cold water faucet at the bathroom sink - older model standard white enamel oval sink, standard two-knob faucet fixture. I went to OSH, and it took the assistant close to 10 minutes to try to match and find the right stem, and even then it didn't look exactly the same. I stopped by Security Plumbing Supply on the way back, and the owner/clerk found one that matched after looking for about two minutes in their stock shelves. I installed it, and it fit and is working well. I'm glad I stopped by Security and am very satisfied with the experience, even though it was for a simple stem. I recommend it to anyone working on plumbing tasks and will be going back. The store in on Pico Blvd, just west of Barrington, not noticeable from the street since they have large areas of wall with brand names painted on them. The is a small entry door from the sidewalk, but it seems that most people, esp. professional plumbers, come in from the door leading to the parking along the alley. The setup of the store is old-school no-nonsense, you walk up to the counter and ask for what you are looking for. read more

I understand the pricing is going to be more. (See below) and the employee Julio was actually helpful, not quite very helpful, almost though! But he told me it would take a week to get a part for my shower and there was no alternative to cap the water so the rest of the tenants in the building could get water??!! In LA??!! Come on, we should have same or next day delivery of any hoysehold part in LA... Then I asked him for the number and repeated what I heard them say it was and he said that was not the correct number and it wouldn't work in any other store! I almost asked to purchase the manufacturers listing number from him but he walked away to quickly shaking his head and uttering something. Luckily I have a good memory and that was the correct number and with that number we found the part right away at another plumbing store!! read more

Don't buy here if you can help it. I stopped by to pick up 2 new valve cartridges for my American Standard bathtub fixture (I didn't have a part number). I don't live near a Home Depot or Lowes. I figured they would charge me a little over what a big box hardware store might charge (which I found out later was $16-$18 each). The list price price was $29 per valve and they charged me $31.50. Not happy and feel like I was ripped off. P.S. I would take it back, but they charge a 25% restocking fee...not worth it. read more

These guys are the best. No nonsense and very experienced. They helped me figure out a solution to an unusual project that required a decent amount of thought and searching for parts. read more

I had to go buy some valves that was missing for my vanity installation. True the guy helped me order what I needed (hence the three stars), but it was not a pleasant experience by any means. I may not know much about hardware, but isn't that the whole point of customer service? The person helping me talked to me as if I were a three-year-old. If you're a young woman who's not a professional I suggest you go somewhere else. I personally would not return to this store again. PS I waited two months so I wouldn't write the review in the heat of the moment. read more

Bunch of old men there not knowing what they are talking about! They wanted to sell a wall mount kitchen faucet for $60 more than it's actual price. Thanks to God I was smart enough to look online before buying . The old man was not willing to accept they are rubbers ! Never recommend this place. read more
