DIY Water FLOW Testing

I will be inspecting a property I bought on Monday and want to know how to preform a flow test on a well. What do I use to fill up the water and where should I pour the water as I go along?

I'm in escrow now and have renters to deal with who are on the property when I test the well on Monday, they don't like the fact they have to move out in less than 30 days and I don't want to piss them off.

Congratulations on the new property.

How long does it take to fill up a bucket?

https://en.wikipedia.org/wiki/Water_flow_test

true well water yield/flow testing is usually done over a 2 hours period. 5gal/minute time 120 minutes is 600 gallons so if you can fill a dozen 55gallon drums in 2 hours you have plenty of sustained flow.  make sure to watch the flow carefully because if the well runs dry for a bit and the pump runs dry it will damage the pump. FHA & VA loans require minimum standards for well quality & flow rates. HUD reg are found here https://www.hud.gov/hud-partners/single-family-handbook-4000-1.  if you don't want to read 900+ pages here's the basics:  flow rate of 3-5 gal per minute sustained for a couple hours is the flow capacity they look for. there is also testing for contaminates in the water Bacteria, nitrates, lead, pesticides. the well should be more then 50 ft from septic and more than 10 feet from property line and 100 + feet from a drain field.   the practical test is if you have multiple fixtures running in the house at the same time will the pressure drop significantly that the pump will run dry for a bit damaging the system.  hope this helps.

I only have one plastic and one metal 55 gallon barrels and what do I do with the water, the well is near a lean to/carport

I'm paying cash from the house I sold, its in escrow now, the well was tested and very low levels of arsenic in it that can be filtered out with a whole house water system with 3 pre filters I am told

Sue, who told you about the water quality, a salesman or somebody with knowledge.
It is an important difference.
Surely you can carry a bucket of water out of the way and tip it.

How do you plan to deal with the renters, you seem to expect trouble?
Is that a realistic situation?
Good luck what are your long term plans?
Can you catch water offthe roof and use that also? Look at my signature.
