Got it done!

Here's what we started with:



And here's where we ended up:






I copied Jay's idea of cutting an access hole and thru-bolting the toilet down. I still have to make a decorative cover to fill the hole.

Once I got the new toilet installed I found it didn't work properly. It would "flush" but it wouldn't empty the bowl. Flapper valve seemed to be stuck, if I pushed it down I'd get a bunch of air escaping and then it would empty for a few strokes. Now that's a bit frustrating with a brand new head, especially for what the Groco cost! It was also back flooding from the exit hose.

The next morning I talked to Patrick and Groco and pretty much all he said was "joker valve". I went back and reassembled the joker valve fitting making doubly sure I had it properly oriented, that the fitting was on square and I didn't overtighten the bolts. Voila! It works as advertised!!

I re-used some of the hose clamps when replacing the hoses. As I tightened one of them down SNAP the bolt head came off, failed due to corrosion. Inspected all of them discarding a couple more that looked scary, ordering a bunch of the AWABs next time I talk to Defender.

The clamp that failed didn't look bad but see for yourself:

Re: Replacing head on PSC 37

Glad I read your post. I rebuilt my Groco(looks like yours) and now it won't flush, just like you described. I'll reexamine the new joker valve.

The slit on the joker valve must be perpendicular to a line drawn across the mounting holes. The diagram that Groco has is not correct.

Thanks, Dale. I'll pop that open today and have a look, if I can find my boat. We are locked in a dungeon of fog today. Al

Re: Replacing head on PSC 37

Over the course of a year, we:

- Rebuilt our old Groco three times (leaked, leaked, leaked)
- Ordered a new Groco (leaked)
- Tried a different new Groco (leaked)
- Tried a different new Groco (leaked)
- Installed a Raritan PHII (doesn't fit that well, and I don't like it, but at least it doesn't leak)

Let me know if yours does not leak. I would love to go back to a Groco if they do not leak any longer. The Raritan fits in the PS34, but the Groco fits much, much better.

All of the above leaked at the big gasket between the bowl and the base.

Re: Replacing head on PSC 37

Bolts at the base of the china bowl. First new groco we didn't check the bolts and leaked all over cause they were all loose. Second time we tightened before installation and still leaked. I took apart, and the only thing i could see out of place between the china bowl and bronze seat was some overspray from the paint they paint the bronze, it was on the gasket and bronze base...see pics.
I thought it was a liquid gasket of some sorts at first but Groco said no.

That's okay, I just stood back across room to view them.

Groco does go a bit crazy with the paint. Another poster in this thread mentioned that his new Groco bowl was uneven at the mating surface causing leaks, perhaps that was your issue. For what you pay for a Groco there should be NO issues.

The Groco is in there now. If it should become problematic I'll most likely switch to a Raritan which means I'll have to create some kind of platform extension for it to bolt to. Doable but not as asthetically pleasing as the current installation.
