If you've noticed your septic system acting up or your pond looks a bit stagnant, you're likely on the hunt for a hiblow hp 80 0117 to get the air flowing again. It isn't exactly the kind of thing most people chat about over coffee, but if you own a home with an aerobic treatment unit (ATU) or a large backyard pond, this little green box is basically the lungs of your entire setup. When it stops working, you find out pretty quickly just how important it is.
The Hiblow HP series has been around for ages, and for good reason. It's widely considered the gold standard in the world of linear air pumps. Specifically, the HP-80 (often associated with the 0117 repair kit or specific model designations) strikes that "just right" balance of power and efficiency. It's not so big that it wastes electricity, but it's beefy enough to handle the oxygen demands of a standard residential septic tank without breaking a sweat.
Why This Specific Pump Matters
You might wonder why everyone points toward Hiblow instead of some generic brand you found on a discount site. The reality is that septic environments are brutal. These pumps have to run 24/7, 365 days a year, often in extreme heat or freezing cold. The hiblow hp 80 0117 is built to handle that constant vibration and heat without melting down after six months.
The "80" in the name refers to the liters of air per minute it pushes out. For most home septic systems, this is the sweet spot. If you go too low, you don't get enough aerobic bacteria growth, and things start to get smelly. If you go too high, you're just wasting power and potentially churning up the tank too much. The HP-80 keeps that steady, quiet hum that lets you know everything is working as it should.
Knowing When It's Time for a Fix
Nothing lasts forever, and even a tank like the Hiblow will eventually need some love. Usually, after about three to five years, you'll notice the pump sounds a bit different. Maybe it's a louder rattle, or maybe it's suspiciously quiet. If you walk out to your yard and don't hear that gentle vibration, or if your alarm goes off, it's time to check the internals.
One of the coolest features of the hiblow hp 80 0117 setup is the safety switch. Hiblow designed these pumps with a "SP switch" that snaps if the diaphragms inside get too stretched or tear. This is actually a genius move. By snapping the switch and cutting the power, the pump prevents the internal magnets from hammering against the casing and destroying the whole motor. If your pump just quit out of nowhere, there's a good chance it just saved its own life, and you just need to replace the diaphragms.
Checking the Filter
Before you go tearing the whole thing apart, do yourself a favor and check the air filter. It's located under that single screw on the top. If it's clogged with dust, grass clippings, or spider webs, the pump has to work twice as hard to breathe. I've seen plenty of people think their pump was dead when it really just needed a two-minute cleaning of the filter pad. You can usually just wash it with some mild soap, let it dry completely, and pop it back in.
The Rebuild vs. Replace Debate
When your pump finally gives out, you're faced with a choice: do you buy a brand-new unit or grab a rebuild kit? Since the hiblow hp 80 0117 components are so modular, rebuilding is actually a very viable option for most people.
If the motor itself (the "block") is still good, a repair kit is a fraction of the cost of a new pump. These kits usually come with new diaphragms, mounting hardware, and that safety screw I mentioned. It's a pretty satisfying DIY project that takes maybe twenty minutes with a screwdriver and a pair of pliers. However, if the pump has been running for eight or nine years and the internals look scorched, it might be time to retire the old soldier and buy a fresh unit.
How to Rebuild It Yourself
If you decide to go the rebuild route, it's not as intimidating as it looks. 1. Unplug everything. Safety first, obviously. 2. Remove the cover. There are usually four screws at the base. 3. Locate the chamber blocks. These are the parts on either side that house the diaphragms. 4. Swap the parts. You'll take out the old rubber diaphragms and replace them with the ones from your kit. 5. Reset the safety switch. This is the part most people forget. If the switch is thrown, the pump won't start even with new parts. You just have to move the plastic slider back to the center position.
Keeping the Noise Down
One of the biggest selling points of the hiblow hp 80 0117 is that it's remarkably quiet. It uses a linear diaphragm design, which means there are fewer rotating parts to make a racket. That said, if you've got it sitting on a hard concrete pad or if the rubber feet have dry-rotted, you might hear a bit of a buzz.
I always recommend placing the pump on a solid surface but using a small rubber mat or making sure the factory rubber feet are in good shape. Also, check your hose connections. Sometimes a "loud pump" is actually just a loose plastic housing vibrating against the metal frame because a screw worked its way loose over the years. A quick turn of a screwdriver can often make it whisper-quiet again.
Why Oxygen is King for Your Septic
It feels a bit strange to care this much about an air pump, but it's all about the biology inside your tank. Your septic system relies on aerobic bacteria to break down waste. These bacteria are "oxygen-breathing" organisms. Without the hiblow hp 80 0117 pumping air into the water, those bacteria die off, and anaerobic bacteria (the smelly ones) take over.
When the oxygen levels drop, the waste doesn't break down properly, which leads to "sludge carryover." That's a fancy way of saying solid waste starts flowing out into your drain field. Replacing a pump is cheap; replacing a clogged drain field can cost as much as a new car. That's why keeping this little aerator running is probably the most cost-effective maintenance you can do for your home.
Buying Tips and Avoiding Fakes
Because Hiblow is such a big name, there are unfortunately a lot of knock-offs floating around online. They might look identical and even use similar model numbers, but they often lack the thermal protection and the heavy-duty casting of the genuine hiblow hp 80 0117.
When you're shopping, look for the official Hiblow branding and check the weight. The real ones are surprisingly heavy because of the high-quality magnets and copper windings inside. If the price looks too good to be true—like half of what everyone else is charging—it's probably a clone that will burn out in a few months. Stick with reputable septic supply shops or verified dealers to ensure you're getting the real deal.
Final Thoughts on Maintenance
If you take care of your hiblow hp 80 0117, it'll take care of you. Keep the area around it clear of tall weeds so it can get plenty of fresh air. Check that filter every six months, and don't wait until the alarm is screaming at you to check on the pump's health.
Living with a septic system doesn't have to be a headache. It's really just about understanding the few mechanical parts that keep the whole ecosystem balanced. The Hiblow HP-80 is one of those rare tools that is actually built to be repaired rather than thrown away, which is a breath of fresh air in today's world. Whether you're just doing a quick diaphragm swap or installing a brand-new unit, you can rest easy knowing you've got one of the most reliable workhorses in the industry keeping things moving under the surface.
