"This review is a long time overdue but I really wanted to give Stuart and his team a shoutout for the great job they did. I had Pipeline to come out to Waianae to install 2 toilets and a shut-off valve at my home. Not only were they willing to come this far, but also, Stuart and his team gave the absolute best customer service where nowadays it is rare. His team was fast, clean, respectful and efficient and his pricing very fair for the job. One toilet installation proved to be trickery than anticipated, but they went the extra mile to get the job done. And when it came time to do the shutoff valve, I really was fully frustrated with finding the public water source. However, Pipeline's team member was persistent and got the job done all while maintaining a great attitude. I would definitely recommend Pipeline Plumbing. As a landlord, I have been through my share of repairs and good companies like Pipeline are essential and just plain sanity saving."

"When I was told the cost of the job would be $505.00 plus tax, I was shocked. He told me that the price was set by the company. I had $60 coupon, so it came out $465.00. Since he’s already at my home, I gave him ok. I couldn’t send him back because I was afraid there would be a charge for the visit whether I use his service or not. The job took approximately 30 mins excluding time he spent loading and unloading his tools. I felt so stupid for paying that much for 30 mins job."

Water treatment & purification system installations and replacements FAQs

In a reverse osmosis system, water from your main line—or from a designated faucet—is pushed through a semipermeable membrane under pressure. The membrane’s microscopic pores trap dissolved solids, heavy metals, and other contaminants, while clean water passes into a storage tank or straight to the tap. The leftover concentrated water simply drains away. The result is clear, great‑tasting water delivered right where you need it.

A plumber can set up a point‑of‑use unit in one to two hours. A whole‑house system is more involved and often takes one to two days because it ties into the main supply line and may need extra plumbing. During installation, the pro mounts the unit, connects the pipes, checks for leaks, and tests performance so you’re ready to pour a glass as soon as they leave.

Reverse osmosis removes dissolved solids, heavy metals, and many microorganisms, giving you water that tastes cleaner and protects your family. Softer water also helps appliances, faucets, and ice makers last longer. Because you’re filling reusable bottles instead of buying single‑use plastic, most homeowners save money and cut waste. In short, you get better‑tasting water, longer‑lasting appliances, and a smaller environmental footprint from one straightforward system.
