Quote possibly a heating oil leak.

On 2020-11-22 by Nick

Detected small pinkish leak on floor in basement under a burner kit that resembles a box.

On 2020-07-28 by Al Iannuzzi

Had an outside oil tank replaced. It is installed in a shed. Went outside to check oil level and the fill pipe that goes int the top of the tank had a hard crusty whitish substance on the thread area.

The small top drain was completely covered in the same stuff. the front of the tank was spotted with this same material. First time since installed 2 years ago

If there is just one oil line between tank and burner that's a 1-line system.

On 2020-06-07 by Richard Garcia

Thanks for your response. You mention a 2-line system, I have a tank (obviously), a tank valve, a line to oil filter and a line into oil pump. This is a one-line system. Correct?

Richard,

You want to use an OSV or oil safety valve.

See OIL SAFETY VALVES, OSVs

for details. The valve goes ONLY on the supply line (if you have a 2-line oil piping system)

OSVs are sold ready to connect to flare fittings.

On 2020-06-07 by Richard Garcia

I'd like to add an oil line shut-off valve before the filter to an existing old system that has one valve at the indoor tank. Which type of valve is needed? It's a Beckett burner and the oil lines are 3/8" copper with flared fittings.
Thanks.

Usually a whistling noise in water or other liquid piping is due to a combination of velocity of liquid moving through the pipe and other factors like pipe diameter, position of valves, obstructions in the piping system.

From your description it sounds as if your whistling noise is related to water piping not heating fuel oil.

Please take a look at the diagnostic suggestions at WATER SUPPLY PIPE WHISTLE NOISE for a detailed explanation.

We have an oil fueled furnace which heats water that runs through pipes all through the house to heat our home.

We currently have the furnace off since the weather is not too bad but a loud whistling keeps happening, it seems when water is turned on. Any idea as to why this is happening? It is very loud and annoying.

Starts off loud and then tapers off. It would do it some when we ran the furnace but thought it would stop when we turned the system off but has actually gotten worse since turning it off.

Again, it seems to be linked to when water is turned on or toilet is flushed or we turn the shower on. Don’t really hear it through the pipes, the source of the sound is definitely coming from the furnace.

If it were air in the lines I would assume you would hear the whistling through the pipes so do you think it could be a bad valve on the furnace?

We have had to put way too much money out on this furnace already this year so hoping if we can figure it out and tell the HVAC company we use what it is, MAYBE they won’t charge us so much to fix it. We had talked about waiting until this fall to deal with it again but since it is still doing it even with the system turned off, we have got to do something!

On 2020-03-18 by (mod) - don't use diesel fuel from the pump as regular oil heater fuel; find oil line leak

Josephine

I can't be certain from your photo but to me it looks as if there is an oil leak in the fuel line, probably to the left of that oval opening thorugh which the oil line is piped, or from an oil burner itself, above that point.

Watch out: About using diesel in oil fired heating equipment, usually diesel fuel sold at the pump, because it is taxed as a vehicle fuel, will cost you more per gallon than buying home heating fuel from a heating oil distributor,

Watch out: a leak in oil piping can lead to improper oil burner operation as air is also drawn into the system. The result can be a dangerous oil burner puffback explosion.
