Description

A pressure tank is an essential part of a pressurized water system that provides water pressure. The tank stores water between the diaphragm and the liner. The pressure tank reduces the number of times the pump needs to start significantly increasing the lifespan of your well pump. The tension of the diaphragm maintains the water pressure within the system ensuring proper operation of all water appliances such as a dishwasher and washing machine and provides a robust flow of water for showering. No maintenance is needed. A properly set-up pump and tank will work as a team to deliver water pressure to your home and provide many years of dependable service. The Red Lion RL34A tank is a 34-gallon vertical tank with a drawdown of 10.8 gallons at 30/50 PSI. It is designed to handle up to 11 water fixtures simultaneously. The RL34A is equipped with a 1-inch FNPT threaded elbow system connection. The RL34A is made of heavy-duty 20-gauge cold rolled carbon steel with a 304 stainless steel connector. It has a triple grade almond paint finish. The liner material is FDA grade polypropylene. The unit is rated at a maximum working temperature of 194 degrees F and a maximum working pressure of 150 PSI. It can be installed in a series or in parallel for increased system capacity. Initial set-up: The tank is pre-charged to 20 PSI in order to transport this pump safely and must be filled with air to 2 PSI below the cut- in setting of the pressure switch. For example, a 30/50 system needs 28 PSI of air in the tank. A 40/60 system needs 38 PSI. To fill the pump with air, use a standard bicycle pump and monitor the pressure using a pressure gauge (not included).This system is NSF/ANSI/CAN 61/CAN 372 tested and certified by WQA.

  • High-quality pressure tank, easy to install and works perfectly
Style: 20 Gallon Vertical
I installed the Red Lion RL20A 20-Gallon Vertical Pre-Charged Pressure Tank a few weeks ago, and it has been performing excellently. Installation was straightforward — the tank is pre-charged and ready to go, so all I had to do was connect it to my existing plumbing system. The vertical design is compact and fits nicely in my utility area without taking up too much space. Since installation, the tank has maintained consistent water pressure throughout my home. It easily absorbs pump cycling and keeps the flow steady, which makes showers, faucets, and irrigation systems feel smooth and reliable. I’ve noticed fewer pump cycles, which should help extend the life of my pump and save energy over time. The steel construction feels solid and durable, and the paint finish looks professional — it’s clearly built to last. One thing I particularly like is the pre-charged bladder system. It eliminates the hassle of manually pressurizing the tank, and the internal bladder appears sturdy and well-sealed. I haven’t had any leaks or pressure drops, and the tank maintains its pressure even after multiple days of non-use. For anyone looking to upgrade or replace a small to mid-sized pressure tank, this Red Lion RL20A is a reliable and efficient choice. I would recommend pairing it with a compatible pump and checking the air charge before installation for optimal performance. Overall, it’s a high-quality, dependable tank that meets expectations and seems built to last. ... show more

  • arrived fast and good condition
Style: 34 Gallon Vertical
It seemed that most negative reviews were a result of ship damage. No particular brand escaped the problem. I was relieved when mine arrived in mint condition. I hope I get a reasonable life-span from this brand. After purchasing this, I found that similar size tanks of other brands can be found at a couple of the big lumber chains for about $100.00 less This tank looks quality--- I hope so. ... show more
