Most galvanized fittings have threads that you would need to undo to get the head off. This can be tricky and frustrating because of the rusting & corrosion that happens with galvanized fittings. I would take some WD 40 & soak the threads you're going to undo, then remove the sprinkler head from nipple on the threaded tee. Hopefully you don't break the nipple off in the tee. Then take a new head & thread it onto the nipple.
I have a hole in my galvanized pipe on my sprinkler where the water just shoots out of it. Basically all I have to do is follow this method to fix it right? Thanks alot for the video.
I have another question and hopefully its not dumb. I have a galvanized sprinkler head that I cannot get off. Can I just saw the sprinkler head off and attach pvc and a sprinkler to that or do nI have to take the whole thing out? thanks for taking the time to answer my questions.
I'm adding a electric valve to an old manual galvanized 2" line. When the valve shuts off, either the compression coupling slips on the pvc side of connection or the pvc breaks loss at one of the connections. Too much pressure?
Yeah, it sounds like too much pressure. Also you need to keep the new valve from moving either by threading the galvanized pipe or by using something like rebar pounded in on each side of the valve and secured with tie wire.
Don't you mean 3/4" copper main line instead of brass? I've been using a Champ CTS (Copper Tube Size) brass dresser tee to make the connection. I'm not sure a sharkbite tee is approved to use underground. Your supplier might know.
@@user-bw5xf3yr3m The problem with above ground applications is the pressure can sometimes drive the pipes apart where you add the compression coupling. I would cut and re-thread the pipes, add a galvanized union and a short nipple and coupling if necessary. That way the water pressure can't drive the pipes apart.
john Kosheluk I've had trouble with them on galvanized pipe that is old, corroded and with flat spots on the pipe. The gaskets in the caps won't seal off on with galvanized pipe in this condition. They work fine on galvanized and PVC pipe in good condition.
Yes, you might have to change the size of the dresser coupling depending on what size your galvanized pipe is.
I enjoyed the video. This Helps alot.
Glad it helped.

I have a leak in one of my sprinkler pipes. I'm going to try this and hope it works. As stated below, hope there isn't much corrosion .

No pvc glue required for those joints?
It's a dresser coupling. Dresser couplings have rubber gaskets that are compressed by the caps to prevent leaking.

Hi kerry this is john frome sprinklers 4 less q how much would a job like that cost
Hi Kerry how do u t into a 3/4 brass main line 4 a sprinkler sys I am thinking of using a 3/4 sharkbite tee is that OK

Can I use a pvc compression coupling on galvanized pipe?
Yes you can.
@@Iscaper thanks for the reply what if my pipe is above ground and the compression coupling would be for the water main?

Kerry have u ever had a problem with those comp couplers

Thank u 4 your input
your links didnt work
Sorry, the links in the description are old and no longer functioning. I've removed them.
