hooking a new plumbing supply line off the dock to the existing plumbing of my houseboat the existing plumbing presntly gets its supply water from holding tanks, using 12 volt on demand pumps. Im ok on getting the regulator check value unit installed for the incoming supply line my question involves the Crown head unit
my question on my head this water comes in from a stand pipe on its own pump to a crown head, do you recommend I leave this alone, or would you use a dock supply in put. (for use when tied at dock) (with a added check valve in place if needed).
right now IM drawing from the lake to flush the head.
One of my thoughts is if I can use dock supply I cut down on the use of this pump. but not sure how all this will fit in with a crown head unit that has its own pump on the rear of the unit.... excuse any info I failed to provided Ill respond if i left something out

If you're drawing from the lake to flush the toilet I'd leave it alone. Connecting a raw-water head to your drinking water supply is NOT a good idea, and converting it to a fresh-water flush would probably be more $$$ and hassle than it's worth. It works now.... don't try to "fix" it.

UhUh The head pumps water only when flushing. It's not broke don't fix it.
You need a valve kit to convert to fresh water flush. The beauty of fresh water flush is quiet operation.

I think it's called a "solenoid valve"; for safety you'll probably also need the "vacuum breaker". Whether there's an actual "kit" I don't know. You'll also have to remove the raw water pump or it's impeller. Shouldn't be difficult. Ask Peggy in "Boatkeeping/Sanitation" and she can help you; or ask Vic Willman on the other site. They're the experts and should be able to tell you what parts you'll need.

What is this fascination with having a freshwater flush? You have a perfectly good marine toilet with all the free water in the world to flush with. As to not drinking water from your tank, that's fine as I do the same, but you may at least brush your teeth or wash your face in it and that e coli is pretty rough stuff. I would not tie my toilet to my holding tank when it is below the level of the toilet. In your house you have a pressurized supply line with a backflow preventer and a holding tank on the toilet where everything flows downward.

The water may be "free" but the parts to convert the toilet aren't! The lake water is also free; and a strainer is about $10.
Though if you have a rubber-impeller flush pump I don't blame you for wanting to change it; those things make an awful racket , especially at 0200!!
Your holding (sewage) tank is on the top deck???? Or is it your water tank?? To be honest it sounds like an odd place for either one.

your right the noise is horrible, I was assuming the noise wouldnt quit, i thought it was coming from the macerator but perhaps your right & that pump is causing it.
your correct in the holding tanks are on top, which is strange they will be moved this fall.
I was hoping I could elimit the incoming lake water when at the dock and use shore water to supply the system then use the incoming lake water when we are out.
the stainer U mentioned is that located on the bottom of the hull or is line prior to coming into the tolet...regardless i know i dont have one on this boat, and sooner or later those particles will glog the pump or the tolet incoming holes

If you have a rubber-impeller flush pump, you don't have to worry about it clogging. They'll pump just about anything. If you have a diaphragm pump (similar to your fresh water pump) you need a strainer.
If you switch over to "fresh" water flush; you're pretty well committed. The "fresh water" heads run on fresh water ONLY, you don't switch them back to lake water when you're out. I suppose you COULD, but it's gonna be $$$$.
Don't make things more complicated than they already are; it'll cost that much more to maintain.

ok ill stick with the impellar pump and noise thats why I ask
if i still have your attention I assume sence i connected the incoming line just above the out going side of the on demand pump i dont need to place a check valve on this line,
as stated earlyier I have a check valve on the incoming outlet where the supply line is attached

You are coprrect in you assessment of the check valve. If you took the impeller out of the Crown you would not be able to use it when out. You would have a plumbing nightmare. By the way welcome to the board. I am moving two businesses and what amounts to 3 households as it wound up being two and 1/2 semi loads just for the house and garage. I am getting close to being moved on the house, I am now starting on the Marina. Another 30 days and I will be back on the board as usual. I will be off for a couple of days when I move my computer. Good luck with your project.

I forgot, never leave the shore water on when you are gone. 90% of all boats sunk at dock is from a line breaking and pumps burn out etc. and down she goes.
