Re: Poor hot water pressure
All the heat traps I've seen -- and I haven't seen them all -- have a circumferential groove around the middle of the trap. If it doesn't have this groove, chances are it is just a nipple installed to make things fit.
I've learned to hate galvanized pipe for water supply lines.
The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
