Clogged Oil Line


Last year I had a clogged oil line between my oil tank and oil fired boiler. It sputtered quite a bit and would set off the trip and only start after pressing the red reset button.

After trying a few things I cleaned out the 3/8" copper line with my compressor injecting 90PSI air through the line. It worked and has been running smoothly up until today.

Today I was in the basement and I could hear the burner do a very intermittent miss. That is the way it started before. First a few misses once or twice a minute and after a few weeks it was a full sputter.

What I would like to know is there something I can do to clean out the line more thoroughly? It is about 30' long and I have access to both ends.

Thanks.

A friend of mine had same type of problem.
Tried your solution. Worked for a bit.
Finally had to clean line out with solvent. Couldn't believe the crud that came out. Keep filters changed & it has been good to go.

Re: Clogged Oil Line


I was thinking of the solvent route. Anything in particular work better? Mineral Spirits, Acetone, Lacquer Thinner, MEK or something else?

Re: Clogged Oil Line


If I recall we used Lacquer thinner. We filled it up a couple of times & let it sit for 10-15 minutes. Seems like it took 3 times to get it clean.

Re: Clogged Oil Line


Not an oil guy, but, two things come to mind. What if the problem is in the tank, and if you are going through the trouble of cleaning the line, why not just run fresh pipe?

Re: Clogged Oil Line


Basically, it is cheaper to clean it. My basement, where the line runs is very difficult to get to. The ends are accessible, but the middle of the run is buried behind a lot of heavy stuff. That is an option, but it is low on the list. It only took me a couple of minutes to clean it out with air, and it lasted a year.

Re: Clogged Oil Line


The question would be, how is this dirt/crude getting into you oil line? How often are you changing your oil filter?

Dirt/crude in an oil line always comes from the oil tank. A good oil filter prevents it from getting to the oil line.

Re: Clogged Oil Line


I don’t know if there’s any truth to it, but I’ve heard that converting to a two pipe system will help clean up sludge and contaminants in the oil tank due to the continuous recirculation of the oil.
It sounds feasible though and shouldn’t be too hard or expensive to do if it’s only a short distance, so may be worth a try.

Running a single line out of the top of the tank. Will lave the sediments in the tank, and prevent the oil filter from restricting so quick. or the sediments from being drawn through the oil filter as easy.

Hey Leo..
I got this stuff Sludge Solve from the plumbing store.. You put some in before you a load a fuel. And it helps get rid of the crap on the bottom of the tank. Maybe it would help you ..

Re: Clogged Oil Line


The tank is at least 30 years old. It is in good condition on the exterior, interior, who knows. The filter gets changed once a year along with the screen, nozzle and a good cleaning. I do the standard maintenance on the burner annually. This is just from years of buildup. I don't know how the previous owner treated the system (20+years ago) but if the house and yard were any indication, he did less than nothing.

Re: Clogged Oil Line


Run a fresh piece of tubing. Flared connections no compression fittings allowed.

Install and old filter assembly at the outlet of the tank without a filter element and install a complete filter element on the outlet of the old assembly then install a new filter assembly at the inlet of your burner. There is an old and wise oil burner man on the east coast that installed this set up on his home system. Keeps the filters replaced, no nozzle change, checks combustion now for over 5 years.

Re: Clogged Oil Line


I ended up doing the same thing as last time. Just pressurized air. My workload is crazy right now and I just don't have time to flush out the lines. Plus flushing the lines would be best done with 2 guys, one at each end.

So the furnace is back to working normally. Probably for another year
