275 gallon tank piping question
the installation on a 275 gallon heating oil tank in the basement started but its not yet complete. as every professional has a technique that's a bit different i had a few questions concerning the installers methods.
1)concerning the fill pipe
the length of the pipes from the tank to the house exit is appx 5 feet.
how much should the fill pipe be pitched? of the two pipes installed but yet to be designated one is pitched about 1/2" in 5 feet and the other about 1" in 5 feet.
also how should the little 45deg. fill elbow with cap be positioned? can it be attached directly to the horizontal end of the 5' long fill pipe or should a short vertical rise/nipple be attached first.
the technician plans to make the fill pipe higher than the vent pipe, that will put the fill at about 48" seems a bit too high for me.
2)the 12 gauge single walled tank is slightly pitched towards the bottom valve, the level vial is slightly cracked, i assume this is enough??
3)in a prior post several respondents mentioned the use of "swing joints" to alleviate settling upon fill. here they were not used but are not code. are these critical?
4)the burner is currently set up with two lines a feed and return, should the new tank be piped the same way or is the return not needed? why do some burners have a return and others not?
i definitely want to be present for the first filling
the installer works under a licensed plumber and seems qualified however there are still variations between a professional who does 3 tanks a month and one who does 3 a year, which is why a ask for your opinions. that said i have a tendency to "over analyze everything"
if there are any critical points i need to be aware of please let me know.
