Gravity Filled Toilet Problems

I have a cabin with no domestic electricity (solar and gas generator) so in stalling a pump is not possible. The water is pumped to a holding tank at 18 feet high and then travels by g ravity to 3 sets of faucets. The problem is that the drop does not create enough pressure to open the valve (3/8th line) to fill the toilet adequatel y. Also, when it does open, it takes a very long time to fill. Is there a top fill toilet, like the early models that had a tank above the toilet?
Are there any fill valves that would work better than a traditional fill va lve that is controlled by pressure. Thanks for all you help in advance.

I have never seen a toilet flush valve set up where pressure had anything a t all to do with the fill valve opening, they all open with a float. 18' e levation works out to about 9psi - enough to effectively fill the tanks, mi ght be a bit slow but bearable. You might increase the speed slightly but installing a bigger fill pipe but it would only be a minor change.

One of the Mansfield brass ball and lever fill valves would offer the least restrictions. Some fill valves do need pressure to unseat and divert to the bowl refill tube. Might take some fiddling to get the bowl to refill via the small refill tube.

Yes. IT is a constant battle to lift the valve and get the water to get pa st a valve of some sort. With little water in the holding tank, the issue gets worse. Thank you

I agree. Thank you. It does seem as though the fill valve does need a min imum amount of pressure to open to fill the tank. I will try one of the ol der models. Jon

I'll go along with the old style ballcock with a float ball. But if that dont work, you could always add a sillcock (outdoor spigot) to the pipes near the toilet and use a short hose to just fill the toilet tank manually.
When I moved into a house that was under construction, I did not get the plumbing installed at first. There was just a water supply entering the building. I was busy getting the exterior of the building completed before winter and since I do all my own home repairs and construction, I did not consider the plumbing a top prioroty. I just ran a garden hose from the water supply into the bathroom, and put a valve on the end of it, using a hose to pipe threaded adaptor. When I used the toilet, I'd just fill the tank with the hose. That hose also filled a bucket that I'd use to wash my hands, or fill a cup of drinking water, and so on.....
This was not the ideal setup, but it served it's purpose until I got the plumbing installed. It sounds like your cabin is just a weekend getaway, not a permanent residence, so you just have to "tough it" a little. It's still better than hauling water in a pail, or having an outhouse.
Of course there are 12VDC pumps you can buy, and run off an auto battery. A solar charger could be rigged to the battery to charge it. A DEEP CYCLE battery is the best for this sort of use.

Thank you. The shower is beside the toilet so I could run another line and put a hose the toilet. Good Idea. I am not a plumber by any means, but I did not know if there were any other fill valves like this http://m.korky.com/product-details.php?product=fill&numR8GT or a low pressure valve? Thank You
