Basin Sizing: Size Your Pump First

[@jdr03272]

If you want to seal the drain tile pipe into the side of the basin, what is the recommended method with these fiberglass tanks? Is there a slightly curved bulkhead fitting that seals better without cracking or distorting the tank wall? Insert a t? Uniseal?

..... I still don’t know what size basin to pick. I really expected to go through the pump options and then hear a formula for basin size relative to pump size. 1 situation probably needs a pathetic 10-30gpm pump another maybe 50gpm. I was going to go with an 18” diameter culver pipe 40” deep for the first and a 24” culver 50” deep for the 2nd. Drill some 3/8” or 1/2” hole around them.

The basin size is typically sized on the performance of the pump. For example, we like to see an average of 6-8 starts per hour and a run time of 15 seconds or more ( longer run times are more effecient for the pump... think highway miles on a car). With the performance of the pump taken in to account (GPM) you would calculate the volume needed to provide the criteria above. An 18" pit would have approximately 1gallon per inch.

@@ZoellerCompany ahh thank you. Looks like the issue is I do not know the water inlet flow. It’s going outdoors. Not even sure it gets wet there actually hahah. Guess after I dig down 5ft we will see in the next rain storm. Was kind of just being proactive incase there was a large rain event. I live in TN and a couple years ago we got 14” of rain in 24hr. Not bad. The problem was it rained the day before that event already saturating the ground 😂

I am looking to purchase the M53 pump kit. This will be for a removable outdoor application when needed. I’m assuming that the pit is the right size seeing that it is sold as a package. Is this correct?

What is your recommendation for somewhere like Los Angeles with unpredictable, inconsistent rain? We got soaked this year, 40”+. Large amounts of rainfall all at once with these storms. Now in the summer and fall we’ll get no rain for 6 months. Seems unlikely that the pump can stay submerged year round.
