I have an underground sprinkler ,(resipricating),that seems to have a leak in the stem.If i reach down to the stem then i feel a large 1.5-2 inch nut on the stem.
There seems to be some water coming out of there.The sprinkler seems to be working fine but there does appear to be a large waste of water coming out of the base as well.
My question is.I would like to fix this and can i do it from the base or would i have to rip up some lawn to do it? Second,how do i fix it, what is most likely leaking and what's it called?
PS: we live in a colder climate and it tends to freeze here in the winter months.
Thank you for your time and effort in this matter.
