Can anybody advise the proper thread type for drainage rods? I'm looking at knocking up a large T handle to go on the end of a rod to bore out a blocked up soakaway but having no luck as to what it is and my thread gauges do not cover that size.
Cheers.
Don't know off hand, the thread on the set I have is shown below:
What type of soakaway is it, rain water? land drains for a septic tank? If it's the latter then good luck with it, all land drains are doomed to failure, it depends how well filtered the effluent is that dictates doomsday.
About three or four years ago I put in a full septic tank effluent soakaway at our place, so far so good...
Just a word of warning in general, a few lengths of drain rod screwed together can wind up if the business end gets jammed, if they wind up by a turn or two and the business end can't be pulled out then there is every chance that a rod or rods can come unscrewed if you let go of them thereby making the problem of the blockage worse.
