Hi all. My house has a vintage sprinkler system that was put in when the house was built in 1965. The lines are copper and the heads that are still original are brass. Over time they have dropped below the surface level of the lawn, so I am trying to raise them. The first two I did had been replaced before so they came off easily. This one has likely been here the full 57 years and doesn't want to budge.
I tried pipe wrenches, then heating the lower end of the brass head with a torch. So far no luck. My uncle said the brass will likely take a lot of heat to expand so I'll try that again. Aside from that I figure I can try penetrating oil. Any other ideas?
Worst case scenario, could i cut it off and rethread the riser? Thanks in advance for your help.
