Hey guys...I was looking at the threaded ends of the bulkheads under my 75 gallon rr tank and and am dumbfounded about what sizes they are. I bought 2 different size threaded adapters to start my PVC pluming with. I bought a 1" female adapter and a
1 1/4" female adapter. On the bulkhead to the return pipe into the tank...the 1" adapter will not thread onto it. It looks as though it is a tad too small. The 1 1/4" however slips over it completely. On the bulkhead from the overflow exiting the tank...the 1 1/4" will not thread onto it....once again..it seems a tad too small. The tank setup was purchased used and the sump (which I am re-doing) had a hose that looked like a vaccum hose going from the the overflow exit tube to the sump for a drain line. The hose going from the retutn pump to the tube going back into the tank was a clear vinyl tube. Attached is a picture of how the sump was setup before I purchased it. My question is: are these bulkhead fittings a funky size that requires a special adapter to attach PVC pipe? I would take some pics...but I don't have my camera with me right now. If I take the "vaccum" looking hose and insert it into the overflow tube as shown in this pic...
it fits nice and snug. I measured the OD of the end and it is 1 5/16" in diameter. Looking a the bulkhead....a 1 1/2" female
adapter looks like it would be way too big. If anyone has any insight as to how to put an adapter on these bulkheads...I would greatly appreciate it. Here is a pic of my overflow pipes if that would help in any way (even though it doesn't some the bulkheads themselves) distinquish what kind of overflow system this is.
Thanks, Jim
