I am a plumber and own and operate a pump servicing company. This was as well of done video as I have seen in a while and will be sharing it during our on boarding procedures. Thanks again and keep up the excellent work!
How can I fix a plastic impeller housing cracked, there’s a little leaking, The other thing is the pump goes off before the float reach the lower level.
Is there a possibility for the static head to be Zero, if the pump is from a small tank downwards? It is for my project, gravity is not enough to pull the water on it's own so i need a pump, it is a from a small effluent tank of 1500L with a flow rate of 10L/min, no fittings, just the pipe loss. Do i need to calculate the distance between the water level in the tank and the pipe for the static head?
You would need to factor in any vertical height increase plus if you want to calculate total head you need to factor in the resistance of all of the plumbing. Even if it is flowing straight down there is some resistance to flow created by the pipe, however it may be insignificant especially because your total flow rate (10 liters per min) is so small.
Great video Thank you! I have a question about soil flow rate. You mentioned 20-25 gpm through Clay soil. How would this change for a 18” diameter & 30” tall basin vs a 24” diameter and 48” tall basin? Obviously the larger basin would flow more water. Is it strictly a linear proportion based on surface area? I would then assume the example was done with a 18” diameter 22” tall basin @ 22gpm through clay i’m guessing = 4500 in sq. Vs 24”x48” cylinder surface area = 10800 in sq So potentially 10.8/4.5 * 22gpm = 53gpm
The 20-25 GPM in clay soil is a general rule of thumb and is assuming a typical 4" inlet to the basin. The basin size would indicate the volume of water being able to pump OUT when the pump cycles but the larger basin may not necessarily indicate a higher flow coming into it. All applications can be difference based on the soil conditions and water table. The rainfall in the area, water table and the soil conditions would all be a part of calculating the incoming flow rate. A perforated basin would increase the volume entering the basin.

Thanks for the positive feedback! We're glad you liked it and found it beneficial!
I just watched and learned …… and have no reason for a pump ….. but I learned something for if or when I do!!
Exquisite explanation.Much appreciated.
Glad it was helpful!
@@ZoellerCompany Would you kindly equip me with the fittings chart and friction loss chart?

is there a different pump for laundry detergent and raw sewage discharge
pro trick: you can watch movies on KaldroStream. Been using them for watching lots of of movies these days.
@Taylor Landon Yea, have been using KaldroStream for since november myself =)
@Taylor Landon definitely, I have been using kaldrostream for since november myself :D

I am looking to purchase a much large pit and two pumps. Is there a number I can call at Zoeller where someone can walk me through what I need?
