Raritan PHII & PHC

The Raritan PHII is a classic American manual marine toilet: a china bowl on a base, with a large double-action piston pump beside it that draws in rinse water and pushes out the bowl contents in the same stroke. A quarter-turn knob switches between FLUSH and DRY, so the bowl can be emptied without letting in more water. It replaced the original PH (1960–1981) in November 1981; pumps built from June 1992 have a cartridge seal on the piston rod, and the universal kit PHRKIIU now fits every generation. It comes with a marine-size (PHII) or household bowl (PHHBII), a gearbox kit turns it into the electric PHEII, and the PHC (2000–2020) put the same pump on the smaller Compact II base; Raritan still makes the spares in Millville, New Jersey.

Wear parts & part numbers

Part	OEM number	Also fits	Note
Service kit	`PHRKIIU`^{1,2,3,4,5,6,7,8}replaces PHRKIICreplaces PHRKII	—	Universal kit for every Raritan PH and PHII from 1960 on, including PHEII, PHC, PH Superflush and Powerflush; replaces the cartridge-seal kit PHRKIIC (from 06/1992, and PHC) and the U-cup kit PHRKII (11/1981–06/1992). Contains valve balls, valve cap gaskets, intake valve O-rings, both shaft seal types (1213 and 1214 parts), flapper valve 1228CW, piston O-ring 1232MS, bowl gasket 1234, joker valve C253, spacer washers, Superflush base seals and 3 packets of Super Lube SL1CC.
Flapper valve	`1228CW`^9,2,3,8	—	Weighted flapper valve (the weight is moulded into the flap) for PHII, PHEII and PHC; fit it the right way round, as the manual shows.
Joker valve	`C253`^10,2,3,8	—	Discharge valve of PHII, PHEII and PHC (and PH Superflush/Powerflush); the duckbill points away from the toilet. A worn joker lets dirty water run back into the bowl.
O-ring	`1232MS`^11,2,3,8	—	Piston O-ring (multiseal) of every PHII, PHEII and PHC pump; in PHRKIIU. With the flapper valve 1228CW and the joker valve C253 it is one of the three parts behind most weak flushes.
Seal housing (piston rod seal)	`1214W`^12,2,5,3	—	Piston rod seal cartridge for PHII/PHEII and PHC pumps built from June 1992 (housing 1200CW, hex nut on top of the pump): cartridge 1214, shaft seal 1214A (flat side up) and O-ring 1214B.
Seal set	`1213W`^2,5,6,3	—	Piston rod seal set for PHII/PHEII built before June 1992 (housing 1200W/1200BW): U-cup seal 1213A, acetal washer 1213B, snap ring 1213C, rubber washer 1213D. Also in PHRKIIU.
Valve kit	`1201` · `LWS` · `1202`^13,2,3,14,5	—	Intake and discharge check valves of PHII, PHEII and PHC, sold singly: valve ball 1201, spring LWS (larger end down) and white cap gasket 1202; 2 of each per pump, all in PHRKIIU. An over-tightened valve cap squeezes the gasket out.
End cap	`1204B` · `1217`^2,5	—	Intake valve cap 1204B (holds the intake valve body) and discharge valve cap 1217 (under the handle socket), PHII, PHEII and PHC.
Valve kit	`1203BW`^15,2,5,8	—	Intake (FLUSH/DRY) valve body with O-rings 1203B1 (small), 1203B2 (medium) and 1203B3 (large), PHII, PHEII and PHC. Replace it if the selector stays stiff after greasing.
Adjusting knob	`1209BW`^16,2,8	—	FLUSH/DRY knob of PHII, PHEII and PHC; fitted correctly it turns only a quarter turn. Older PHIIs had a knob without the two grip wings.
Vent valve	`1203W`^17,2,8	—	Air vent: the square fitting on the front of the pump that lets air in when pumping dry (PHII, PHEII, PHC). Replace it if the pump is hard to work in DRY only.
Bowl gasket	`1234`^18,2,3	—	White gasket between bowl and base, PHII, PHEII and PHC; in PHRKIIU.
Piston, rod & O-ring	`1212W`^19,2,5	—	Piston rod, supplied with piston O-ring 1232MS; PHII, PHEII and PHC. Replace it if the rod is scored where it runs through the shaft seal.
Pump cylinder	`1200CW`^20,2,5,8replaces 1200Wreplaces 1200BW	—	Pump housing (cartridge-seal type) for PHII/PHEII and PHC, with seal cartridge 1214W. Replaces the 1200W/1200BW housing of pre-June-1992 pumps, whose worn seal bore could only be cured with a new housing.
Pump assembly	`PHIIPUMP`^21,2,22	—	Complete pump without handle; bolts onto the existing base of PHII, PHC and P101/P102, with joker valve and discharge fitting. Keep the old handle. Also brings a pre-1992 pump up to the cartridge seal.
Pump handle	`1208W` · `1210`^23,2,24,5	—	Retractable handle with grip 1208W (current PHII handle, 11 in; the 2005 manual lists 1206W) and handle socket 1210, which screws onto the piston rod above the yoke 1211PL.
Discharge elbow	`1222AW`^25,2,5	—	Standard 90° discharge fitting with flange, 1½ in, PHII/PHEII/PHC; straight version 1222B; held by bolts 1115 and flange nuts 1223B.
Port fittings	`1236AW`^26,2,5	—	Spud assembly: the rinse water inlet on the PHII bowl.
Seat & lid	`1238SC` · `1245SC`^27,28,2,5	—	Slow-close seat and cover: 1238SC for the marine-size bowl 1237W, 1245SC for the household bowl 1244W. Older lists: 1238A and 1245.
Electric conversion kit	`P104E12` · `P104E24`^29,2,5,7	—	12 V / 24 V gearbox and motor: turns a manual PHII into the electric version (sold as the PHII to PH Powerflush conversion) and replaces the drive of PHEII models; the 2005 manual calls the PHII kit PHECKII. Not for the PHC, whose Compact base has no provision for it.
Silicone grease	`SL1CC`^2,3,8	—	Super Lube, for the piston rod (protects the shaft seal); 3 packets come with kit PHRKIIU.

Service intervals

Task	Interval
Lubrication	Every spring and autumn, more often with heavy use: Super Lube (SL1CC) on the piston rod to protect the shaft seal; grease the other moving parts too^2,5,3
Pump seals	On condition: when flushing gets weak, fit the complete PHRKIIU; piston O-ring, flapper valve and joker valve work as a set^8,1
Joker valve	On condition: renew the joker valve C253 as soon as waste water runs back into the bowl^8,1
Hoses & clamps	Regularly: leaks at the toilet and hose connections, clamps, hose condition, seacocks, wiring (PHEII) and the in-line strainer²
Winterising	At every lay-up: drain both hoses, then draw about 1 quart (just under 1 l) of non-toxic antifreeze in through the intake and pump until it comes out of the discharge; leave it in until spring. Antifreeze poured into the bowl only protects the discharge side^2,5
Season check	In spring: grease the piston rod, flush the antifreeze out with about 1 gallon (just under 4 l) of clean water, reconnect the hoses, open the seacocks and check for leaks²

From the PHII owner’s manual L584 (rev. 01/26) and the 2005 PHII/PHEII manual; the rebuild advice comes from Raritan’s technical FAQ. Raritan gives no hour-based intervals.

Good to know

Check which PHII you have before ordering: a hex nut on top of the pump where the piston rod comes out means the post-1992 cartridge seal (1214W); a snap ring and a loose rubber washer mean the 1981–1992 pump; a chrome knob on the front means an original PH. The universal kit PHRKIIU fits all of them.⁷
Weak or no rinse water usually comes down to three worn parts: piston O-ring 1232MS, flapper valve 1228CW and joker valve C253. Replace all three together and grease the new O-ring with Super Lube.⁸
Before fitting a new cartridge seal, wrap the threads and flats of the piston rod in electrical tape so the seal is not cut. Fit the seal flat side up, only snug the cartridge (about 30 in-lb, roughly 3.4 Nm) and do not let the piston drop into the housing.³
If a pre-1992 pump keeps leaking at the shaft after new seals, the bore of the old housing is worn oval. Fit the 1200CW housing or a complete PHIIPUMP; more seals will not cure it.²⁰
Hard to pump in DRY only means the air vent 1203W is stuck. Hard in both modes points to a blocked discharge line, a full holding tank or a clogged tank vent; test by pumping into a bucket through a short hose.⁸
A Raritan bowl only keeps a little standing water when there is a vented loop in the discharge line; fit one with its top about 4 in (10 cm) above the top of the bowl.⁸
