Hey there, thanks for swinging by my little corner of the blog. I’m Jake, and if you’re reading this, chances are you either work with fire safety gear, are tasked with keeping a building’s emergency setup up to snuff, or maybe you just stumbled here looking for something that doesn’t sound like a stuffy old safety manual. Either way, you’re in the right spot—today we’re talking about something I deal with every single day as a rubber fire hose supplier: how to actually keep those hoses working when you need them most. Not just the “do this, don’t do that” checklist from a training video, but real, actionable stuff that’s saved me from getting calls at 2 a.m. about a hose that won’t expand when the fire hits. Rubber Fire Hose
First off, let’s cut to the chase: rubber fire hoses aren’t invincible. I’ve seen too many clients wait until a drill or (worse) an actual emergency to realize their hose cracked at the nozzle, or the lining peeled away from the jacket because it was left coiled the wrong way for years. As someone who’s been supplying these for 12 years, let me tell you—proper maintenance isn’t just a box to tick. It’s the difference between a hose that sprays water where it needs to go and a mess that does nothing but waste time when every second counts.
Let’s start with the most basic step that almost everyone skips: after every single use, clean that hose immediately. I don’t care if you used it at a small grass fire, a dumpster fire, or a drill at the local school—rinse it out right away. Here’s why: even tiny bits of ash, dirt, or charred debris get trapped in the rubber lining or between the jacket and the rubber core. Over time, those little grit particles act like sandpaper. When you coil the hose, they rub against each other, wearing holes in the lining from the inside out. I had a client last year who lost a whole batch of hoses because they waited a week to clean them after a apartment fire—half the linings had rubbed through so bad they leaked even at half pressure.
How to clean it right? Don’t just blast it with a garden hose from 10 feet away. Take the nozzle off, connect it to a pressure washer set to low (no more than 150 PSI—high pressure will damage the rubber’s outer coating), and run water all the way through. If you’ve got caked-on mud or grease (hey, some fires involve those commercial kitchens, right?), mix a mild, non-abrasive detergent with warm water and let it soak for 15 minutes before rinsing. Oh, and for the love of all things fire safety, never use harsh chemicals like bleach or ammonia. That stuff eats away at the rubber’s synthetic bonds, making it crack and degrade way faster. I’ve seen a hose turn brittle in 18 months because a maintenance tech used bleach to “disinfect” it—total overkill, and expensive too.
Next up: drying. This is another step that gets glossed over, but it’s make-or-break. A lot of people just drape the hose over a fence or a railing and hope it dries. Bad move. If you leave it coiled while it’s wet, mildew and mold will grow in the folds. That mildew eats at the rubber, and it also makes the hose heavier, so when you go to stretch it out, the rubber sticks together and rips. Worse, if you store a wet hose in a hot place—like a utility closet in the middle of summer— the trapped moisture will cause the rubber to break down from the heat, too.
The right way to dry it? Uncoil the entire thing and hang it in a cool, shaded, well-ventilated area. Don’t hang it over sharp edges (like that metal fence I mentioned) — rub the outer rubber with a cloth first to protect it. If you’ve got a hose drying rack, even better—those are designed to hold the full length without creasing. Let it dry completely, all the way through, before you coil it back up. I tell all my clients: if you can still feel dampness in the folds, it’s not dry. No exceptions.
Now, when it comes to coiling and storing—this is where I see the most mistakes. A lot of guys just grab the two ends and twist the hose into a tight circle, the same way you’d coil a garden hose. Nope, that’s for garden hoses, not fire hoses. Tight coiling creates permanent kinks in the rubber jacket. Those kinks weaken the hose over time, and when you stretch it out during an emergency, a kink can turn into a full-on crack that makes the hose useless before you even get it to the fire.
What’s the proper coiling method? The “flat coil” is the one we teach all our clients, and it’s way easier than it sounds. Lay the entire hose out flat on the ground, straighten out any twists, then start rolling it up tightly along its length—like rolling a poster, not a circle. Once you have a neat roll about 2 feet wide, take the hose’s own end connector (the male or female fitting) and tuck it through the roll to secure it. No extra straps needed, no tight twists. If you have a larger hose, you can do the same thing but split it into two rolls. Pro tip: mark the start of each coiled section with a piece of tape so you never accidentally stretch a kink when unrolling it later.
When storing, keep those coiled rolls in a dry, temperature-controlled place. Avoid basements that get damp, or attics that hit 100 degrees in the summer. I recommend keeping them off the floor too—on metal shelves or racks, not the concrete. Concrete holds moisture, and that moisture will seep into the bottom of the hose roll, leading to mildew that I mentioned earlier. Also, keep them away from any chemicals, like cleaning supplies or propane tanks. Even fumes from certain chemicals can break down rubber over months of exposure.
Let’s talk about inspections, because even if you do all the cleaning and drying, a hose can degrade without you seeing it. I tell every client to do a full visual check every 3 months, and a pressure test once a year. For the visual check: uncoil the hose slowly and run your hands all over it, inside and out. Look for small cracks, blisters, or discolored spots on the rubber. Blisters are a big red flag— that means the lining is separating from the jacket, and that hose can burst when under pressure. If you see any cracks that are longer than a quarter inch, or any missing chunks of rubber, replace it. Don’t try to patch it. Patching a fire hose is a temporary fix at best, and it’s way too risky when you need it to hold 100+ PSI of water.
The annual pressure test is non-negotiable. I work with a local testing company that does this, and it’s cheap—way cheaper than replacing a hose that bursts mid-fire. They hook the hose up to a test pump and run pressure up to 1.5 times the hose’s rated working pressure (so if your hose is rated for 150 PSI, they test it at 225 PSI). If it leaks, bursts, or has any weird bulges, it’s done. And for the love of safety, don’t skip this. I had a client who skipped a pressure test for two years, and their hose burst during a drill—soaking a bunch of firemen and delaying the drill by 45 minutes. That’s a preventable mistake.
Wait, what about if you store a hose for a long time, like if it’s a spare for a rural fire department? A lot of departments have spare hoses that sit in storage for 5, 10 years. What then? Same rules apply, but maybe add a step: every 6 months, uncoil it, inspect it, and re-coil it with a fresh fold to prevent those permanent creases. Even if it’s unused, the rubber is aging. UV light is another enemy—if a hose is ever left out in the sun for more than a few hours (which it shouldn’t be, anyway), the sun’s rays will break down the rubber’s molecular structure, making it brittle. So if you ever have to lay a hose out in the sun during a job, cover it with a tarp when you’re done for the day.
Let me address a common question I get: can I patch a small leak? The short answer is no, not for long-term use. I’ve seen guys use rubber cement and a patch from an old inner tube to fix a tiny leak, and it works for a few months. But fire hoses are under constant pressure when in use, and that patch will come loose eventually. It’s not worth the risk. When a hose shows signs of wear, replace it. I supply hoses that last 10-15 years if they’re taken care of properly—skipping maintenance will cut that life in half, easy.
Here’s the thing I wish more people understood: I started this business because my dad was a fireman, and I saw how stressful it is when you’re counting on your gear. A fire hose isn’t just a piece of equipment—it’s a tool that saves lives. So taking 30 minutes after every use to clean it, an hour every 3 months to inspect it, and a couple hundred bucks a year for a pressure test is nothing compared to the cost of a damaged hose, or worse, an accident because a hose failed.
