Break the Unions apart and put some pipe dope on the face of the unions, good Idea to do whenever you use a union!
Great tip Slim!
Another related tip I learned from my 47 years of union plumbing/pipefitting-experienced father:
an alternative to pipe dope and/or Teflon tape is a methacrylate ester-based thread
sealant (
not thread
locker) for hydraulic and pneumatic threaded connections. I prefer the
54540 Permatex Pneumatic/Hydraulic Sealant (Click Here)I use this sealant on anything I
never want to leak at a threaded connection. Hundreds of applications later, not one has ever leaked in 12 years. The product is not inexpensive but you can find the 1.2 oz. bottle on Amazon for about $25-26.
BTW... my dad reads all of your tips on this website and thinks you are a really good plumber! Big compliment from my dad, trust me.
FANTASTIC-looking installation sceptre74!
