The pump squeaks when I pump it, what's wrong?

This was most common on the PHII/PHEII units that were manufactured before the cartridge seal pump series (1200C).

In the early electric drive units, the drive arm squeaked against the pump housing regardless of how much grease was applied. The cure is to convert to the 1116BW drive arm kit - the material has been changed in the drive arm to one that is compatible with the material of the pump housing. In manual units, the most common source for squeaking is the bushing area just beneath the seal. As the piston rod pumps up and down, the rod squeaks against the bushing area. The cure for this is to put SuperLube on the piston shaft; we also recommend a TWK.

Another area for squeaking is when the bushing area wears and the corners of the piston scrape against the cylinder bore. Sometimes vegetable oil put into the toilet bowl will stop the squeak temporarily.

For a permanent cure, the pump housing must be updated to the 1200CW.

I've replaced my piston shaft seal and it still leaks, what is the problem?

Usually the problem is a worn bushing area in the 1200B pump housing, which would necessitate replacing the pump housing with a 1200CW.

A possible lesser problem would be that the replacement seal wasn't installed correctly. It is installed with the flat side up, plastic washer on top of it and snap ring installed with curved surface down. Using the manual handle to install the snap ring, press it until it just contacts the white washer, then stop. Do not compress it as far as it will go.

I wish to order a repair kit but don't know which one I need; how do I identify which one I need?

Units manufactured prior to 1981 are identified by a chromed shutoff valve handle on the front of the toilet pump; this is the PH series and uses repair kit #PHRK.

Units manufactured 1981 - June, 1992 are identified by a plastic on-off knob at the front of the toilet pump and a pump shaft seal held in place by a star washer-type snap ring. This is the original PHII series and uses repair kit #PHRKII.

The current series (6/92 - present) is identified by a cartridge-type pump shaft seal with a hex nut at the top of the pump housing where the piston shaft goes through. This unit uses repair kit #PHRKIIC.

The square nut in front of the pump body leaks; what is wrong and how do I fix it?

The square nut in front of the pump body is an air inlet valve that allows air into the top of the pump cylinder during dry flush operation to stop any Vacuum kick. Inside the square fitting is a check valve.

In units manufactured between 1981 and March, 1992, a small black joker valve was used; in units manufactured after March 1992; a more advanced valve is used.

In either case, remove the fitting and rinse it with warm, clear water. Reassemble. If it still leaks, replace it (part # 1203W).

The intake valve handle is hard to turn; how do I make this easier to rotate?

Remove the round handle, unscrew the packing nut (1204B) and remove the intake valve body (1203B). Grease the three "O" rings with SuperLube or other PTFE based grease. Reassemble, referring to correct alignment of valve in the PHII owner's manual. If it continues being difficult to turn, replace the intake valve body (1203B).

Note: older PHII series valve handles didn't have the two "wings" on the handle to aid in turning it. Customer may wish to purchase a new handle (1209BW).

How do I winterize my PH II marine toilet?

Refer to winterizing instructions in owner's manual.

No water stands in the bowl, why not?

Raritan toilets are not by themselves designed to hold water unless a vented loop is installed in the discharge line with the top of the loop generally 4 inches higher than the top of the bowl. The higher the loop the more water will remain after each flush. See the specific toilets installation manual for specifications and loop height limitations.

Note: Vented loops may need to be installed higher for safety reasons (see installation manual for further details)
