how does this type of overflow work as where it goes over the tank it is higher than the water level so it wont get over :confused::confused::confused:

They work like this. This demo and the explanation is in the sticky threads.

I can't say that you should buy it. They don't tell you what the name of the pump is (if it has one) and you don't get an option for replacement impellers. When the impeller needs to be replaced, it will cost you the full price of the next pump.

The Quiet One QP13 will pump more water with less electricity. The only draw back is that it costs four dollars more (it will be well worth it when you need an impeller). You will get the four dollars back eventually just by saving electricity. The pump curve online says that the QP13 will pump 400 gph (four turnovers) but the one in my book says it will pump 600 gph (six turnovers). Either way, the pump in your link will pump only about 2-2.5 turnovers, which is pretty light on what you really need.



Btw, if the math isn't simple enough, the Quiet One will pump twice as much water while using less electricity.

No, you saw one LIKE it work. When the inside loop is above the tee, it will not hold its prime when it is shut down. That is why I said to make the bottom loops even. You don't run into problems when you don't try to reinvent the wheel.

Well, before you scold me for asking a question and giving my opinion, please verify what I wrote.
I stated:"I have seen this type of setup work". This statement would elude to the fact that I have seen other siphon setups like it, not this one in particular. If I thought I knew exactly how it would work I wouldn't have asked for an explaination. Explainations are key when people who don't know ask questions. Tact is always useful.:thumbsup:
 
That wasn't scolding you. I was pointing out that you made the same mistake of the OP. The one you saw worked because it was properly dimensioned.

The failure in writing is that it can be translated different ways by different readers. :(
 
those checkvalves are great.. but do yourself a favor... get a second one and keep it handy... ive yet to suck air out of my overflow without getting the check valve wet.. and ive never had one work after it got wet (both the duck bill and the spring kind)
keep the one you have where it is and use it till it fails... but once it fails dont remove it.. keep it where it is and put the new checkvalve on the other end of the hose..

im half asleep so if that makes no sence.. its going to go.. overflow-broken valve-hose-good valve
