I was given two power pressure toilets by a friend for the bathroom I am installing... Well neither one fit's when all is said and done, but I did a little reading as to how they opertae and... well... they seem to me to be an awesome surge device for creating flow :)

The tanks are about 14" long and maybe 14" in diameter.. They are steel tanks lined with plastic throughout the inside.

The pressure tank basically builds up water preasure from the house line then releases it all at once when flushed. It seems to me these could be hokked up to a pump and a mechanicaly timed device could flush them at the set intervals.

Whatya think?

BTW I normally would not take a used toilet but these are high end seats thatare $$$ ;)

Man brings new meaning to the term bedee, lol

I gues it would depend on the power? from what I have seen they are pretty powerfull, that could be a problem with knocking things over or ripping the tissue off the coral. Also take a look at the bubble factor. Might be worth a dry run.

I have one in my house. I love it.... never have to flush twice...
and it scares the hell out of people who aren't expecting the loud whoosh when it flushes.

Here is how it works:
The plastic tank is air tight. When the water gets turned on to the unit water fills the tank half way before the air intake gets closed leaving (at this point the tank is half water and half air) the water pressure begins to compress the air to an amount equal to the water pressure feeding the tank.

I.E. the water pressure is 90 psi then the toilet will flush at 90 psi.

When you flush... you open the valve and the air expands at a rapid rate forcing the water out of the tank at (i.e. 90 psi). The air valve opens and brings in fresh air as the water begins to fill the tank restarting the process.

The problem with your plan is this:
The house has a consistant water pressure. (more or less)

If you use a pump... the pump would have to run continuously OR have a VERY good one-way valve.

Once the pump shuts off the water will back push out with the same force as the air pressure... maybe back into the fish tank.

Also a pump will begin to cavitate extremely quickly if there is more tank pressure than pump pressure.


I like the idea though.

Hmm Great reply RSD!!

It's such a simple application.. I know microbubbles would be many but like we saw in the last mtg it looks kinda cool and natural.. Well even at shallow depths it would probably be too much. The money spent on a good enough valve might negate the project as a whole...

I think this would be great to try out on an outside pond, then refine the system to work outside where you have room to blow off excess water. LOL hey worth a try regardless.

Hmmm a reef tank in the bathroom... hmmm well my wife wants another bathroom! Why not build her one around my reef tank!! ;) lol Sure it beats the newspaper but I read Anthony Calfo articles :)

I'll set up a test outside.. Who knows! Maybe it will be the next rage in sprinkler technology! ;)
