PH Powerflush

The only electric marine toilet that can also be manual! The PH Powerflush is an electric marine toilet that allows the user to easily switch over to manual operation if needed. While it is not a macerating electric toilet it does allow the user to push a button and it will automatically flush the toilet.

The design of the piston pump dates to the 1950’s when the first PH was developed for the Navy. Many improvements over the years have made Raritan’s PHII the most recognized and popular among those who demand the best. While the PH Powerflush does not have the familiar PHII in the name it utilizes the PHIIPUMP on a new base and a fully redesigned electric gear box.

The advantage of the PH series over competitive units is that the piston housing is much larger allowing not only for easier flushing if being flushed manually but also for more efficient flushing as the pump is able to move more water in and out of the bowl. A full-size joker valve on the outflow means less probability of clogging when flushed as well. A common problem with piston type toilets is that sometimes water builds up in the bowl so Raritan add an air valve that allows the user to turn off incoming water and the user can continue flushing or pumping without building up pressure in the pump.

This toilet provides the best of both worlds for the person desiring electric operation but the peace of mind of manual backup.

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.
