The main feed into my house is 1 1/4 and the line into the meter is 3/4". So what I am planning on doing is this. There is a 3/4" nipple coming out of the meter on the house side into a coupling and then a line which elbows into the house. I am planning on leaving the 3/4" nipple in and putting a bell reducer to open into a 1 1/4" line which will then elbow into the 1 1/4" feed into the house. I understand now that the feed that the valve is on must be the same diameter as the feed into the house but I do not think that it requires 1 1/4" into the meter itself. Any advice on this first part would be appreciated if I am planning anything that sounds stupid.
Secondly, is there a code in California to anyones knowledge which requires me to put a ball valve on the line just before it enters into the house? I seem to have heard that somewhere but to my knowledge the only shutoff I have every been familiar with is the one on the meter. Please set me straight on this one.
Thirdly, how do I bleed the line once I have installed the meter. I understand that this is good practice but not sure how to do it.
Fourthly, is the shutoff at the meter sufficient to be horizontal or do I need to tweak it as far as it will go to shut off the line after the meter. It will go horizontal and then about 22 1/2 degrees but I had heard horizontal is a positive shutoff. Is this true?
Lastly, the bracket comes with two bolts ( three holes on the bracket) ... instructions says that it can either be mounted to a stud or in alligator molly's that come with it. I had always thought that going into studs was a must but maybe I am wrong.
