I know, I wasn't thrilled about the lack of pressure. However, with the MP Rotators, 30 psi still gave me the coverage I need, more than I needed in some places. The radii you see on the design are designed at 30.

I'm going to do that. You guys usually use a pvc compression fitting to tap a copper line? Once I make the connection and install a T, how do you hook up a pressure guage to that? Do I have to install a temporary piece to hook the guage up to?

If it's copper, I usually sweat on a copper T, then a female adapter and go to PVC there. I'm not a fan of compression fittings because I've seen many, many failures with them. Of course, we have very expansive clay soil in most of my service area that contributes to that so YMMV.

That's what I was afraid of lol. I have zero experience sweating copper. Obviously doing irrigation I will have to do it at some point...Any pointers on that?

I want to say no to a sweated tee, but I realize that's our basement-meter custom at work, because water companies simply won't stand for that practice. It's either flared or waterworks-compression, because any leaks between the street and the house would be at the expense of the water company.

A good waterworks compression tee with a threaded side outlet is probably the quickest way to tap in.

Ya I see the pros and cons of both....the guys at my local Ewing are the ones who had recommended the compression fitting with a threaded T....Maybe I should just try that to start with and see what kind of results I have?

Ewing does not sell what you really want. As far as I know, these fittings are only stocked by the big-pipe suppliers that sell to water purveyors. Any place that sells fire hydrants will stock, or can quickly obtain, waterworks compression fittings. Manufacturers include Mueller, Ford, and MacDonald.

So what's the difference between a waterworks compression fitting and the compression fittings that Ewing carries?

Huh? Every home here is a sweat tee in the basement. Never seen a compression tee for a tie in.
