Best out there!

This product (P-Free) works great for waterless urinals. I was skeptical at first but wow was I surprised. I highly recommend this product and will continue to keep a supply on hand.

This stuff really works… I will be adding this product to my facility PM schedule. I highly recommend this product! You won’t be disappointed.

Drain Punch is by far the best drain clearing juice I’ve ever used for plumbing and I recommend it to anyone who wants to clear a tough clog !

⭐⭐⭐⭐⭐ I don't write reviews very often, but I felt compelled to share my experience with Drain Punch and the team behind it at Lamberti Sales. Like many homeowners, I've used a variety of drain cleaning products over the years. What immediately caught my attention about Drain Punch was that it's acid-free. In a market full of harsh, highly corrosive products, it was refreshing to find a solution that prioritizes safety without sacrificing effectiveness. It gave me much greater confidence knowing I wasn't introducing dangerous acids into my plumbing system while still getting excellent results. What truly floored me, however, was the level of customer care and support I received from Lamberti Sales. Exceptional customer service has become increasingly rare, but the team at Lamberti Sales exceeded every expectation I had. They were responsive, knowledgeable, professional, and genuinely invested in helping me. At no point did I feel like just another customer or sales opportunity. Instead, I felt like they truly cared about my success with their product. It's easy to find companies that make claims about quality or customer service. It's much harder to find one that actually delivers on both. Drain Punch impressed me as a product, but the people behind it impressed me even more. The combination of an effective, safer, acid-free drain cleaner and a company that provides this level of support is something you simply don't come across every day. My experience with both Drain Punch and Lamberti Sales has been outstanding, and I can recommend them without reservation. Five stars all around.

I purchased Drain Punch because it was recommended and let me tell you, it WORKS! Saved me from having to call a plumber and I only used half of it, so I will have more next time there is an issue. Very personable sales team, thank you Carl for reaching out and giving me helpful advice. I will be back next time I need a product that truly works. Thanks again.

Drain Punch is by far the best drain cleaner I have ever used. I used to have a recurring slow shower drain but ever since I found DP, my problem is solved. Fast acting, no smell, just results. I try and keep a bottle or two around the house at all times. Highly recommend!

I highly recommend Drain Punch! I came across the product randomly while watching YouTube for alternatives to Liquid Plumber, Drāno, and those other brands that never seemed to get the job done. When my bathroom or kitchen sinks started getting sluggish, Drain Punch cleared them out quickly and thoroughly. Because my house was built in the 60s and has an older plumbing system, I always keep a six-pack on hand for plumbing emergencies. THANKS DRAIN PUNCH CARL!

Carl with Drain Punch is so knowledgeable and helpful. Drain Punch is a miracle worker!

We are a small company where every year or so the urinal clogs with mineral and calcium deposits in the 2 inch galvanized steel drain pipe. Previously we have had to cut out a t section of steel drain pipe to snake a vertical section below the tee clear. This year the unit clogged completely for a while and then later opened somewhat. We used P-Free by pouring a full quart in to fill the trap. Then we let 2 more quarts trickle though the trap into the main pipe slowly by inverting the bottles into the urinal with the small spout into one of the drain holes. This process maximised the clogs exposure to the Pfree. Each bottle trickled through in about 45 minutes. Afterwards we flushed the Pfree from the system with multiple flushes . The urinal is now clear and can be flushed multiple times in a row without back up.

My plumber recommended Drain Punch, and it worked great. It took one bottle to clear a 70-year-old bathroom, drain but I'm not complaining. My plumber said this would be much easier than trying to snake the drain on such old plumbing.

Great product and great customer service! We use the P Free on our bar urinals.

Outstanding product Drain Punch and outstanding customer service! Carl himself called to thank us personally for ordering. This is our second order. Our drains were taking a while to drain, but no more. Hubby uses now for maintenance purposes once a month through out the house. No issues. Easy to use. Couldn't ask for a better product.

We saved at least a thousand dollars AND a great deal of inconvenience by using DRAIN PUNCH to dissolve a difficult to access clog. Drain Punch solved the problem much better than products from the grocery store that waste both time and money. We are very impressed by the science underpinning DRAIN PUNCH, the instructions on the bottle, and the company's customer service. We knew we were headed in the best direction when we asked for Drain Punch at plumbing supply and the counter staff said "ahh, the good stuff"!

I'd give 6stars if I could. For the product as well as Carl Lamberti's professionalism on the phone. Drain Punch was recommended to me by my plumber, who said because of it's formula, it was safe to use in older homes that had galvanized pipes. I now use it every six months as a precautionary treatment in the bathroom, tub and sink, and never had another problem. It keeps my 70 year drain pipes running free. The only problem is, that I have to order it on line because no plumbing supply in up-state N.Y. carries this product.

Great product have used the drain punch on stubborn water fountain drains and on condensate lines. Has saved a lot of time for myself and other technicians.

This stuff works great !!! My condensate drain are flowing like new again !!!

I met Carl at NFMT and he sold me on Drain Pumch immediately. Between the demos and my experience with draino never working, I had been in the market for a better product. Lucky enough I stumbled across drain punch and will be using it for any clogged pipes I have going forward.

Best product ever invented ❗️❗️❗️❗️

I needed advice on some issues for plumbing and the gentleman there really helped me out. He talked me through the issue, educated me and helped solve the problem. These people really care and want your business. I look forward to working with you all again.

Drain punch is a great product just follow the directions easy to use

Carl is one of the most dedicated sales professionals in the industry. It has been my experience that both he and his products are equally hard working.

Works great!! I use regularly

Works great for tub and sink drains!
