I won't waste time on the history but i have a clogged or collapsed line from the skimmer to the pump.
I have tried a drain king in both directions, a snake, an air compressor and have been able to establish a weak flow ... then when i vacuum it clogs completely again within a minute or two.
If i close the valve to the skimmer the pressure remains constant. If i close the valve to the main drain i lose pressure as i close it which i read is indicative of a clog and as i continue to close it i continue to lose pressure then lose prime.
When i snake from the pump i can feel several feet of obstruction before i can't go further .... if i snake from the skimmer i can only go a foot or so before i get stuck and the snake starts curling up on itself.
Any final suggestions or should i break out my shovel? I am planning on having a plumber i know come in and try to snake it hoping that he might have some luck. I figure if he can't get it the pipe probably collapsed? Any other last ditch suggestions?
If i have to dig i am hoping to dig under the concrete and access the bottom of the skimmer and then run new lines to the pump ..... i figure i can either drop the water below the skimmer or else put my gizmo in and blow the line with air to get it dry so i can glue it. Does that make sense?? How are the pipes typically attached to the bottom of a skimmer?
Am i in over my head?
