Need plumbing advice...

[ervine]

Hi guys...

While my original setup would not flood during a blackout, after adding my external skimmer and chiller, it's almost 100% confirmed that a blackout will cause my sump to overflow....

As my sump is really tiny (1.5ftx1ftx1ft) it can't really hold a great deal of water... I was wondering if there's any good sources for check valves or something that can be easily adapted to hoses to prevent backflow from happening...

Please advise...

Thanks,

Ervine

No one knows where to get check valve?

[typrobin]

check valves are not 100% fool-proof....the water will still flow back into the sump,juz at a slower rate....

the best solution will be to get a bigger sump.

hi,

why dun you try to re-examine the ways to connect your equipment and water level.

bec with check valve, the flow will be reduce, and upset your current water level setting.if may want to do a simple diagram of your connection, and water level for everyone to feedback.

If you have a small hole at overflow & return pipe just on the surface of the water to break the siphon, I dont see why the sump will flood? Unless you are using more than 90% of your sump capacity.

Sump is small.. that's the first point..

Second point is I have 3 routes that will flood my tank...

1st being the sump to tank output (which already has a hole) this alone will raise water level in my sump by about 1-2"

2nd being the chiller which likewise is set high enough to cut the siphon action but the reservoir in the chiller still dumps enough water into the sump to raise it by 1-2"

3rd being the skimmer which when empty will also raise water in sump by 1-2"

I can afford only something like 3-4" before my sump floods... (sump was meant for my 1ft nano last time!!)

I'm also apprehensive about the check valves.. it'll kill my flow tremendously siah...

Okay here's a schemetic diagram of my water flow... it's relatively to scale... you can see how small my sump is and how little leeway there is for possible flooding...

Please advise.. thanks!

Like previously mentioned, can drill hole at the top of the pipe (which can still screw up if a snail or some creepy gets stuck.....

Or.... increase the height of your intake by 1" or so..... Without all the figures hard to calculate, but you will be suprised how much water 1" from a large tank of water is.

I already have the hole drilled.. but it's not enough... water from the skimmer and chiller chambers are enough to flood the tank...
