Water HeaterS

Water Heater installations are part of our bread and butter. This has lead to us having great relationships with supply houses and water heater manufacturers ensuring you will not only get the highest quality units. But also ensure that you get them at a great rate by leveraging our multi-decade relationship with them.

Water Softeners

By protecting your homes with proper water treatment you not only enhance the satisfaction of those who end up living them you also directly increase the value of the household. As time goes on our water quality becomes a bigger and bigger question. It only makes sense to ensure that every home you build is equipped to protect the home and those who live in it against future dangers and unnecessary maintenance.

We have sold and installed tens of thousands of water softener systems across hotels, restaurants, casinos, food, and meat processing plants, including the ATT sports arena in San Antonio Texas. And we won’t stop until all the water systems in Southern Utah are equipped with a proper water filtration system.

We exclusively utilize Certiflow water treatment systems. These systems have proven themselves time and time again as the best option in the water treatment industry for full home water filtration or water softening.

Certiflow water treatment systems are the most reliable and longest-lasting equipment in the waterworks world. Through these systems, we are able to utilize the latest innovations in water treatment technology.

Water Filtration

Softening water is a great first step. However having proper full home water filtration is just as important. Due to the affordability and long lasting nature of properly installed and sized filtration equipment it is always a better idea to have it, than to not have it.

We would not live in a house without proper filtration and it is our position that no one else should either.

Like our water softener systems we also utilize carbon filtration technology provided by Certiflow. In all areas of their operation they have proven to be the ideal option for anything that they provide.

Bathroom Plumbing

Whether commercial or residential bathrooms it is safe to say that we definitely know our way around a toilet and shower. Every single day our technicians expertly install virtually every aspect of a bathroom across one of the jobs that they have. 

No matter the size or creative dimensions of the bathroom we have the skill and scale required to get the job done.

Drain Cleaning

Drains are of utmost importance for any home or building owner. You will always want them clean and clear.

It might be bad to try cleaning drains using chemicals, as they tend to harm the actual pipes. Why take the risk when you can search for professional plumbing, right?



Some times new homes or renovations require us to check all of the drains and lines leading to the house to ensure that they are of equally as high of quality as the plumbing we will install in the house.



We are equipped to handle this task no matter what is required.

Sewer Line Repair

Leaking and clogged sewer lines in buildings can create a massive negative impact on your plumbing fixtures. 

We always hope it is not the case but sometimes sewer line repair is necessary before the property is ready to go. 

If this does happen to case we are equipped to handle this at any scale. We have seen it all and there is no job we cannot handle quickly.

Water Treatment Systems

We put so much premium on eliminating organic and inorganic deposits from water. Insufficient systems can shorten the operational life of water infrastructure.

Worry no more about unsafe water with Marlin Plumbing 

Our Certiflow systems are something you can stand behind. Not only are they beautiful but they also provide a quality of life improvement that really cant be explained. It has to be experienced. We are experts in this area and we will make you look like one too!

Marlin has come out twice due to leaks. They treated us well, they did a good job, and had affordable rates for the the plumbing outside of my home... that wasn't covered by home warranty. Hot water heater replacement, outdoor pressure valve replacement and a leak we couldn't find that turned out to be the fridge water line. I appreciate the professional service that they did and will continue to use them for my plumbing needs. I'm very glad I chose this family business, you can tell they care.read more

Fantastic service and great people. They arrived on time and ready to solve my water heater issue. They were able to figure out the problem quickly.... Rather than make me wait or make another appointment, they went to get the part needed and came back to fix it same day. I was very impressed and pleased. Grateful to have hot water again! I would definitely recommend!read more

The gentleman who replaced our water heater was first rate. His estimate was exactly the amount we paid! He completed the removal and installation... exactly the length of time he estimated. In addition he was very personable and give us some helpful advise on other plumbing issues, that were unrelated to the problem at hand. Finally he arrived exactly on time. I'm 77 yrs old and a former engineer this was my best experience with a repair person in my entire life.I would rate Marlin Plumbing with 10 stars if I could.Tomread more

We got a water softener and washing machine box installed about 6 weeks ago. Our laundry room looks so much better with the box installed and it has... been so nice to have the water softener. I will definitely use Marlin Plumbing again next time I need something. They were prompt getting us a quote & doing the work, the bill was exactly as expected, the work was good quality, communication was great, and they even cleaned up after themselves which was impressive…not everyone does that. I also felt their pricing was very good.read more
