Aquatec 6800 Booster Pump Kit for up to 100 GPD Home RO Reve
✅ PROS
- Draws only 1.2 amps at 24V DC — efficient enough to run continuously without spiking your electric bill
- Compact footprint (about 5 x 3 inches) mounts easily to wood or metal cabinets with included brackets
- Auto shutoff pressure switch integrated — stops the pump at 80 psi so you don't blow out your RO membrane
❌ CONS
- Does NOT include a power supply — you'll need a 24V DC adapter or the Aquatec PS-1 separately, which catches many first-time buyers off guard
- Flow rate drops noticeably with 75+ GPD membranes; this kit is really optimized for the 50 GPD sweet spot
The Verdict
If your reverse osmosis system takes forever to fill a glass of water, or your pressure tank sits at a pathetic 5 psi, you already know the pain. The Aquatec 6800 booster pump kit is the most common fix for this — and with 215 ratings averaging 4.3 stars, it’s clearly doing something right. But it’s not a magic box. Here’s what you actually need to know before buying.
What’s in the Box
The kit includes the Aquatec 6800 diaphragm pump itself, a 24V DC motor, mounting bracket, and the necessary tubing adapters (1/4" John Guest-style push fittings). You also get the pressure switch assembly that wires inline. What you do not get is the power supply — that’s a separate purchase, and it’s the #1 complaint in the reviews. One buyer put it plainly: “Wish I’d known I needed the transformer. Add $25 to the price.” Budget for that before checkout.
Performance and Build Quality
The Aquatec 6800 is a diaphragm pump rated for up to 100 GPD, but here’s the nuance: it performs best with 50 GPD membranes. At 75 GPD, you’ll see a drop in flow — not a failure, just a slower production rate than the membrane’s rating suggests. At 100 GPD, you’re pushing the pump to its limits. For a standard under-sink unit with a 50 GPD membrane, this pump delivers a dramatic improvement: tank refill time drops from 2+ hours to roughly 30–40 minutes.
The pressure switch cuts in at around 40 psi and shuts off at 80 psi, which protects your membrane from overpressure damage. The pump body is glass-filled polypropylene — durable enough for years of service, and the diaphragm is replaceable if it eventually wears out. Wiring is straightforward: two wires for the pressure switch, two for the motor. If you’ve ever wired a thermostat, you can handle this.
What Buyers Consistently Praise
The recurring theme in positive reviews is reliability. Multiple long-term owners report 2–3 years of continuous operation without a hiccup. One reviewer noted: “Installed this in a camper van with a 12V-to-24V converter. Runs my RO system every day, zero issues.” Another praised the quiet operation: “Barely hear it under the sink, just a soft hum.” The auto shutoff also gets consistent credit — it prevents the pump from dead-heading against a closed valve, which is what kills cheaper pumps.
Where It Falls Short
Beyond the missing power supply, there are two honest tradeoffs. First, the pump is not silent — it’s a diaphragm pump, so you’ll hear a rhythmic pulsing. It’s not loud, but if your RO system is near a bedroom or living area, you’ll notice it during refill cycles. Second, the included mounting brackets are bare-bones; you’ll want to add rubber grommets or foam padding to reduce vibration transfer to your cabinet. Some buyers also mention that the 1/4" tubing connections can leak if you don’t push them in fully — seat them firmly and you’ll be fine.
Who Should Buy This
- Well owners with low incoming pressure (below 40 psi): This pump is your solution. It’ll make your RO system actually usable.
- RV and camper van builders: The low amp draw makes it ideal for 24V battery systems.
- Homeowners with 50 GPD RO systems: You’ll get the biggest performance jump here.
Skip it if you have a 100 GPD system and expect full rated flow — you’ll be disappointed. Also skip it if you’re not comfortable with basic wiring; while simple, it’s not a plug-and-play device.
FAQ
Q: Will this work with any RO system? A: Most under-sink RO units with 1/4" tubing connections. It boosts incoming water pressure to the membrane, so as long as your system has a standard inlet, it’ll work. Countertop RO systems are generally not compatible.
Q: Do I need a separate power supply? A: Yes. The kit doesn’t include one. A 24V DC 1.5A adapter works perfectly, or you can buy the Aquatec PS-1 power supply.
Q: How do I know if I even need a booster pump? A: Check your incoming water pressure with a gauge — if it’s under 40 psi, your RO system is struggling. Also, if your tank takes more than 2 hours to refill after a draw, a booster pump will help.
The Verdict
Rating: 4.2/5
Buy it if you have low water pressure and a 50 GPD RO system that’s frustratingly slow. It’s a proven, reliable fix that pays for itself in convenience.
Skip it if you have a high-capacity membrane (75+ GPD), expect whisper-quiet operation, or don’t want to deal with sourcing a power supply separately. For everyone else, the Aquatec 6800 is the workhorse booster pump that gets the job done — just budget for the transformer and a few minutes of wiring time.
