PH PowerFlush – Dual Operation, Total Confidence
Reliable. Convertible. Timeless.
The PH PowerFlush marine toilet is the rare solution that gives you full control, no matter the conditions. Designed for boaters who demand reliability, simplicity, and flexibility, it blends the best of manual and electric toilets into a single rugged system.
Powered by a time-tested piston design originally developed for the U.S. Navy, this dual operation marine toilet allows seamless switching between electric and manual flush modes — perfect for energy conservation, backup redundancy, or situations where battery power just isn’t guaranteed.
Whether you're cruising offshore, docked at a marina, or riding through rough seas, the PH PowerFlush keeps working — quietly, efficiently, and on your terms.
Electric or Manual — It’s Your Choice
Unlike typical electric marine toilets that leave you stranded during a power loss, the PH PowerFlush gives you instant manual control with just a pin and a handle.
- Electric Mode: Push a button to activate the motorized flush cycle
- Manual Mode: Insert the included handle to convert instantly — no tools, no downtime
- Hybrid Advantage: Ideal for extended cruising, emergency use, or conserving energy off-grid
Oversized PH Pump = Powerful, Effortless Flushing
At the heart of this system is Raritan’s legendary PH Pump — a large-diameter dual-action piston that's 66% larger than other marine heads on the market.
- Moves more water per stroke = fewer pumps needed
- Built-in full-size joker valve reduces clogs
- Lever-style handle gives smooth, ergonomic operation
- Air vent system prevents pressure buildup and allows water-free flushing in heavy seas
This isn’t just another pump. It’s a high-performance marine toilet engine built for real-world boating.
Space-Saving Design. Easy Install. Flexible Options.
The PH PowerFlush installs easily into any compact head where a manual toilet once lived — no major rework needed. The newly designed base fits into tight spaces and builder-precut marine head areas.
Available in:
- Compact marine bowl size or household-style bowl for more seating room
- Freshwater or raw water intake options (dedicated tank or pressurized)
- Updated telescoping flush handle — more leverage, less space

PH PowerFlush – Frequently Asked Questions
Q: How do I switch from electric to manual mode?
A: Just remove the locking pin and insert the manual handle — it takes seconds. No tools or rewiring needed. You’re back to flushing, even if your batteries are dead.
Q: Does this toilet macerate waste?
A: No — and that’s the point. The PH PowerFlush uses direct pump-through power, which reduces moving parts and simplifies the system. It’s less prone to failure and easier to troubleshoot than electric macerators.
Q: Is this a good choice for cruising or offshore boats?
A: Absolutely. It’s one of the few marine toilets that lets you conserve power or operate without any at all. Ideal for extended voyages, older boats, and energy-conscious setups.
Q: What’s the difference between this and a standard manual toilet?
A: The PH PowerFlush has a larger piston, stronger flush, and optional electric mode — so it flushes faster, cleaner, and with less effort. It’s also quieter and more customizable than many mass-produced manual heads.
Q: Can I install it myself?
A: Yes — it’s designed to fit the same footprint as many small manual toilets, and the plumbing setup is straightforward. If you’re upgrading from a standard head, this is one of the easiest marine toilet installations you’ll find.
Q: Can I use fresh water with this toilet?
A: Yes — with a dedicated freshwater tank or manual fill, it’s possible. However, if you want to use your pressurized onboard freshwater system, we recommend using the Raritan Fresh Head instead.
