I'm stuck on this one.....Pump?Pressure? Not sure

Ok people..

I was really stuck...Called Jim for some advice and had to rudely hang up cause the head guy was coming up on me..Sorry Jim....This dude is such a pain in the @$$ that I really starting to hate him..My bad brother..Your advice was solid and I was able to follow most of it...

Ok I have a video uploading..

Here is the facts that I can see/ understand..I will try to explain them as clear as possible..

There are two centrifugal horziontal? pumps that have each 1.5 inch pvc on the intake side and 1.25 on the outflow, soon there after the inch and a quarter T's to a 30-40 gallon pump in 1 inch pvc...After the T is a ball valve on each side......After the ballvalve the two outflow sides of the pump T together and as a single pipe go to a filter...The filter is assumed to be very caked with sh!t as its bleeding out its sides pond scum..and this is nasty water, non potable, drainage water from the highway...

They both are assumed to be pulling about from 20 feet from the bottom of this pond...

The issue is that the system is not running up to previous pressure when we turned it on...

I am not a pump guy, and far from a dirty water expert...


After checking all valves for debris, nothing, I cut the pipe after the valve. Turned on the valve and for a second the water would shoot out of the 1 inch poly pipe 10 feet after a while it would just pour out no more than 8 inches...

The Rep in the pump house noticed the secondary pump was not coming on..

is it due to the Cloged filter?

is the second pump in the crapper?

I'm lost.......

picture of me before the great woods show in mass..

hehe

I am thinking drop the filter out of the housing and see if that helps. If not, you need to check the inlet for debris. Last would be the pump but It would be the last. Are both pumps triggered off the same pressure switch, or are there two?

When was the last time you drained the pressure tanks then checked the air pressure on the diaphragm?

Sounds to me like you have a volume issue rather than a pressure issue, more than likely due to a clogged inlet to the pressure tank. Pretty much what I think is happening is just enough water is entering the storage tank to allow for the initial discharge. After that is expended nothing remains.
Kind of like my bank account after my divorce.

Also you didn't describe how the two pumps are linked and controlled. A demand switch or is the system meant to sustain a fixed pressure via a pressure switch.?

I have seen many systems crap out due to a clogged orifice in the pressure switch not allowing the contactor to drop which is why the second pump may not be starting. You can by pass the actuator with an insulated handled screwdriver and simply press down the contactor and listen for the second pump to start.

Or I may be more full of crap than I usually am and the advice I offered smells worse than my morning constitutional.

I'm wondering if there is just algae muck blocking the inlets or there is some marine life stuck too.

Ed needs a web cam mounted on his head so we can see what's going on "live" during the exploratory.

Sounds like it could be clogged foot valve(s).
I'd also check the threaded pvc connections at the pump intakes. If the pumps got hot from lack of water then the pvc fittings may be damaged, allowing air to be sucked in causing loss of prime.
