The Rheem Commercial Universal Gas Water Heaters, exemplified by the Universal 100 Gal. 199,900 BTU Natural Gas Water Heater, are engineered for seamless integration into constrained retrofit environments while boasting the capacity and capabilities to withstand rigorous commercial demands. Featuring a user-friendly spark-to-pilot electrical ignition system for swift activation, this model caters to diverse hot water applications with its expansive 100 Gal. tank and numerous water connections. Noteworthy for its compact footprint, minimal vent height, and versatile water connections, it stands as an optimal replacement unit. It's imperative to note that this model necessitates a 120-Volt power source. Additionally, its attributes include a space-saving design, facilitated by its short stature and narrow jacket diameters, alongside top, front, and rear water inlets/outlets, ensuring unparalleled installation flexibility. The inclusion of a System Sentinel LED diagnostic system ensures systematic operational verification. Furthermore, its robust tank design, propelled by proprietary steel formulation, patented multi-flue architecture, and dual porcelain enamel coats, yields a superior heat exchanger design. Stainless steel burners, equipped with a raised port configuration, offer durability and facilitate easy maintenance. A low-profile automatic flue damper minimizes overall product height, while a factory-installed full port, full-flow brass drain valve expedites servicing. The direct spark to pilot ignition system optimizes energy efficiency by igniting solely upon heat demand. Corrosion resistance is fortified through a patented anode design incorporating multiple magnesium rods. The unit is pre-installed with CSA/ASME rated T and P relief valves, ensuring safety and compliance. Fully insulated with energy-saving materials, and featuring a gas control system with adjustable thermostat settings, this model offers versatility and efficiency. Moreover, Rheem's universal line provides a range of configurations from 35 Gal. to 100 Gal. models, available in natural gas and liquid propane variants, catering to diverse preferences and requirements.

Great hose!
Style: Standard Grip, Size: 100ft, Color: Chartreuse
5 stars without hesitation. This Flexzilla Garden Hose 5/8 in. x 100 ft. is legitimately one of the best hoses I’ve used. It’s actually flexible like advertised, doesn’t fight you every time you move it around, and it feels way more durable than the cheap stiff hoses from big box stores. I honestly don’t understand a lot of the complaints, mine has held up great, doesn’t kink nearly as bad as others I’ve owned, and is super easy to coil up. Solid hose.

If you want to buy your last hose then flexzilla is your hose.
Style: Standard Grip, Size: 50ft, Color: Chartreuse
O.K. if you are reading my review I can honestly say that I don't think anyone knows what they are buying with this hose like I do as Amazon has the record of when I bought 100 feet of this hose. Long Long Long term user=purchased in 2017. I used this hose today and it looks-feels-works like it did the day I hooked it up on my reel. So flexible you can use it for a tourniquet if required. Hot-cold it don't matter this hose is the best. I am 70 yrs. old and it is the best hose I ever used in my life. Buy this hose once and then be done. Never kinks and not to heavy when moving around. Buy some and get on with whatever work you need to wash and then roll it up and forget about it.

Hose kinks.
Style: Standard Grip, Size: 100ft, Color: Chartreuse
I bought this hose 2 months ago and really like how light it is and easy to pull around the yard. However, I am having a problem with it kinking all of the time. It is really frustrating to have to go back and straighten it out when I am watering.

Excellent product.
Style: Standard Grip, Size: 50ft, Color: Chartreuse
I've dealt with many different brands of hoses, took into account quality and price. After many disappointing purchases I can finally say "I got the right one this time". It is exactly as advertised, lightweight, flexible and very easy to handle. You won't go wrong with Flexzilla garden hose!!!

There is no substitute to Flexzilla Hose
Style: Standard Grip, Size: 100ft, Color: Chartreuse, Style: Standard Grip, Size: 100ft, Color: Chartreuse
I absolutely love this hose! I purchased roughly 300 feet last year for use in my garden. It's extremely light and durable when you are dragging it around. For the most part it is kink free. If there does happen to be a kink down the line, a quick tug fixes the problem. No leaks, no shrinkage. Easy to install on any hydrant. DEFINITELY compact compared to other heavy hoses. The best part, it's super easy to coil it back up and hang in the tool shed. So I ordered a couple more 100 footers. I will definitely buy more.
