We recently removed a pair of Headhunter Royal Flush heads from the boat. Nothing at all wrong with them, but after rearranging our waste tanks as part of a larger renovation, they turned out to be the wrong heads for the application. Details on this model can be found on Headhunter's web site, here: http://www.headhunterinc.com/products/Toilets/neoclassic.html These were used on a household freshwater system with a Grogo Paragon pump. As such, they come with Headhunter "adder" kits, which are basically just solenoid valves that you connect to your boat's existing fresh water system. This method works best if you have a high-volume water system aboard such as the Paragon. You could also use a dedicated pump (for raw or fresh water) from Headhunter (or compatible model). One head will also need a seat, which Headhunter will be happy to sell you but I think household "elongated" models will fit. Depending on how your plumbing is arranged, you might need to add a 1-1/2" check valve to the discharge line (as we did). You will need four lag bolts or through-bolts to attach it to the sole; I recommend nylon washers between the bolt and the china (the original mounting hardware was not salvageable). These heads, new, sell for over $1,300. At that price, new, you'd still need to order the seat and adder kit or pump separately. They are vitreous china, so I will not ship them, for fear they will be damaged in transit. I am currently in Deltaville, VA for another few days, and heading south from here, and would be willing to keep them aboard for a short while if you are on our route. Alternatively, you can contract with someone from U-Ship or similar to pick one or both up -- I've boxed them up in the boxes from their replacements. I completely washed and scrubbed these after removal and they're in clean condition. There are no chips or damage of any kind. The design of this model and the way they were installed on the boat involved PVC hard pipe which I had to cut, so the one (very slightly) dirty job for the buyer will be to cement on a new fitting, either a barb to go directly to 1-1/2" hose, or a threaded fitting to attach a check valve, depending on your installation. While the china parts of the fixtures are now very clean, it's simply impossible to get the internal plumbing whistle-clean inside. Whichever type of fitting you require, you'll need it to have a female "slip" end for the PVC pipe. There are no seals, flaps, valves, or any other moving parts other than the aforementioned fresh water solenoid (or dedicated pump) in a Headhunter head. Email me directly if interested, or you can call or text me on (4O8) 892-6227. I hate to see these go into the landfill when they are in perfectly good condition. Take one or both, your choice (they are identical, except for one missing a seat, which broke on removal). -Sean m/y Vector lying Deltaville, VA
