I am going to try explain this to you the best I can.
there is reason to adjust the siphon. my pump cant pump any faster, the siphon isnt going to say "oops, i should slow down..." i am going to have to adjust it.
As I stated earlier, the only way to adjust flow of water via siphon tube is to adjust water level of the tank. Rise it if you want to increase the flow or lower it to reduce the flow. If you manage to increase flow rate any other way, please let me know ... maybe you can rewrite the Bernoulli's Principle. You can decrease the flow by placing valve ... but this is counter productive.
if i dont adjust the rate of my siphon, it will be breaking all the time.
You don't. You adjust the return from the sump.
my siphon goes faster than the pump regularly, it was stated above,
Slow and calm down and then read my earlier post. I believe it was you who stated,
im not worrying about a flooded sump, because the siphon will break before that.. So if this the case why are you trying to reduce the water flow of the siphon rather than regulating the return flow.
either my sump is filling, and my siphin breaks, or my main tank is being filled, bacause the siphon is adjusted too slow. how do you get them perfectly balanced?
I am sorry, no matter how you try to convince anyone, they both cannot happen unless you alter something. It is either the sump overflow or the tank overflow.
The sump simply cannot oveflow.
But let us assume that you have siphon rating of 1,200 GPH and pump rating of only 200GPH. Since the pump is unable to keep up with siphon, more water will drain to the sump than returning to the tank. As this happen the water level in the tank will drop below the critical level and siphon will break and stop water from draining to the sump. Bu the pump will continue pumping water to the tank and till the water level in the tank raised above the critical level. When this happen siphon should start automatically (that is if you have it setup correctly ... if not you can expect disaster).
Now what happen if the siphon can only drain 200GPH and the pump is rated at 1,200GPH. The pump will return more water than the siphon can drain and the tank will overflow. And this why you need to place valve on the return and adjust the pump.
Another criteria that must be taken into consideration when setting up a sump, is it size. The sump must be able to hold the amount of water that will drain from the tank during pump failure. If the sump isn't large enough, your sump will overflow incase of pump failure or if the pump isn't able to keep up with the siphon. The amount of water that will drain during these incident is easy to calculate. Take the difference in water level between the overflow box(s) and multiply by the surface area and divide 231. Another word, atleast this amount of space should be available in the sump.
If you did, you wouldn't have this problem. I explian the sump/overflow process so it will give you better idea of how it works.
