When you go for your float they have then there [cheap]

Is it like a one way valve F&F. Can you explain. Ta.

TT, a foot valve is a non-return devise, attached to the suction end of the pump.
Non-return meaning water in the line will not flow back into the tank or syphon.
Hope this helps...
kind of tough to get yr head around, but worth a try.

So a foot valve ensures ur inline pump is always primed?

correct go to the top of your class!
..and as the teacher use to say...
don't take your books because you wil be back soon!
TT I think the only bit I neglected to say was, it is to ensure the pump is always primed.

Thanx C1, it takes me a while to get some things but when i geddit i goddit.

To slow my pump cycle down i think i will T off at the fishtank and return a fair bit of water to the tank. Given this will be full of fish poop i will have some sort of screen filter that this water drains thru. It will be something simple that just slides over the side of the tank so it can be removed and rinsed easily. Something like flywire.

By the time fish po goes through a pump it will go through a flywire you need some kind of filter mat i just return mine it goes to the bed next time

watch those foot valves TT, Ive got one on my pump and afew of my little silvers got caught in it. two probs with this: 1, dead fish, 2, pump loses prime and runs dry/hot....not good. a finer mesh is the obvious solution.

not sure what pump your using but rather than diverting water could you not throttle back flow with a ball valve?

using the 750watt spa pump and happy to have some water come back in to aid aeration and lengthen fill cycle. Can this foot valve be in line or does it need to be in the tank? My fishtank pump is in line, not in the tank.

Hope you have had the pep talk with ya fish worms, i am nearly ready to roll!!

Well you can have a non-return valve at any point, but the foot value,
is generally that, at the foot- the bottom of the suction side.
A non return just stop water flowing back from where it came.
(sic) non return.

at work we quite offten put them on the discharge of the pump but the lines normaly go up several floors and would cause a flood in the plant room if they drained back to tank

if your pump is below the lowest point you will drain the tank to then gravity should keep it primed for you i owuld have thought, with that said if you dont have a solenoid valve somwhere thenthe tank will probably drain even when the pump is off
