I was helping out my father in law install an on demand water heater last night. The heater has 1/2" threaded pipe fittings coming out of it. So, we ran to the store and grabbed all the stuff we needed (valves, fittings, etc) and came back and installed it. We pressurized it and had a few leaks. So we removed it, tightened them up as much as we thought safe and reinstalled it. Still leaking. We used teflon tape on every joint and I'd say nearly half of them leaked. This seems ridiculous.

So, what tips do you guys have for getting threaded pipe connections not to leak?
