one-pipe overhead oil line

MikeR_4

We run single-pipe overhead lines all the time with no problems. 1) Everything MUST be tight. 2) Train all of your personnel(including delivery drivers) on how to properly bleed these systems. If you don't "Power purge" them with the pump running, you WILL have problems.

one-pipe overhead oil line

In order to eliminate possible oil leak liability from from a broken or damaged oil line running across the floor we are considering going with a single pipe overhead line.we plan to do this mainly on short (less than 20 ft.) runs.We would use two pipe onlonger runs.has anyone seen problems doing this?

Going Overhead

A teacher whom I respect taught me that when going overhead go right to a 2 pipe system. Less work for the pump and eliminates loss of prime issues.

On overhead lines i always use a Tigerloop with Garber filter just before the Tigerloop. It will give the benifits of a two line system but still only the flow of one pipe sysytem, half the chance of a leak and no return line to leak.

Stick with the oil line on the floor, you'll have alot less problems.

Use either ENT or a metal threshhold over the line.

Install an oil safety valve at the tank.

Mike though the running feet is important you want to pay close attention to the feet of lift. And keep in mind that what ever goes back down to the burner cancels out the lift. I’d stay with a one line system as long as you don’t exceed the vacuum of 6” and I would personally prefer the tiger loop also if a two line system was a must.

With a two line system you’re using the total gear suction capacity of the fuel unit which increases the vacuum. With the tiger loop you’ll greatly reduce that vacuum.

We do one line overhead coming from the bottom of the tank and dont have any problems 99% of the time

Al,

You say no problems 99% of the time, however I seem to find that with over head lines that you get more sooting through the year as you eventually pull Hydrogen out of the oil and it creates a bad burn also as the micro bubbles add up the vacccum increases agian, however with the tigerloop the soot/ microbubble situation goes away, and when it does happen you no something has gone wrong.

one thing to watch out for

When running over head ines, you must have a tigght system. Any air leaks wil cause you to be back priming the line if you don't install a tiger loop or my favorite, a cheeter loop. No compression fittings. A check valve si not necessary if you have an air tight line. Good luck.

I agree. Avoid two pipe ESPECIALLY 2 pipe overhead. The floor joists act as a tuning fork. It's a guaranteed call back.

Tiger Loop it if you are going overhead, period.
