We make your emergency a priority for us, scheduling service as quickly as possible to resolve your problem. Our plumbers are the same way—they treat your home with respect and consideration.

Our prices are flat-rate and upfront, so you don’t have to worry about inflating prices as the job goes on.

"Contacted Mr. Rooter on a Saturday and they quickly sent Dave and his assistant. Dave diagnosed the problem, provided a couple of solutions (after discussing each with me) and once we settled on a plan-of-attack, he got right to it. Dave was great! He fixed the problem, the cost was reasonable and they cleaned up after themselves. I highly recommend Mr. Rooter. (P.S.- ask for Dave)."

"Carini installed my mini splits a few years ago and promised me the world with their warranties. Well, turns out they botched something during the install and all of the refrigerant leaked out. They want $2,200 to refill and re-pressurize the line. Since they cross-threaded the screw that led to the leak during installation, this should be covered under the "Lifetime Craftsmanship" guarantee. Instead, they're trying to charging me a full day of labor to fix their mistake. Support on this issue has been dismal. It's been 16 days since they first diagnosed the problem and I still don't have a timeline for when this will get fixed. I chose Carini because of their warranties and their service record, but its all smoke and mirrors. You've been warned."

"Excellent service! We scheduled Plumbing Plus to replace the hot and cold cartridge's in a sink faucet and a tub pop-up drain and overflow gasket. Jared N. quickly assessed the problems. The faucet was so corroded with water deposits that it could not be dismantled to simply replace the hot and cold cartridge's. So Jared replaced the entire faucet with a high quality replacement. After the tub pop-up drain was replaced, Jared checked for leaks by looking in a 'trap door' in the ceiling below the tub that was left after the tub was replaced in an earlier remodel. Jared discovered that the entire tub drain was leaking and need to be replaced, which he did. He also corrected a problem with the drain pipe left from the previous remodel. Although the job was much more complex than expected, Jared was professional, efficient, and extremely cheerful throughout . We highly recommend Jared and Plumbing Plus"

FAQs for water treatment & purification system installation and replacement projects in Oceanside, CA

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.
