Tiger Loop noise

Kevin M. McKeon

I have a oil fired hot water baseboard system. (small ranch) recenctly I had an underground oil tank removed and replaced with one in the basement, aprox 20 feet from the boiler. Everything is now on the same level. The installer ran a 1/2" single line from the tank to a tiger loop, then two lines to the burner. The line from the tank to the tiger loop is fastened to the ceiling joists, so the main line is obviously higher than the burner and the tiger loop. The tiger loop is aprox 8 feet from the boiler and mounted aprox 3-4 feet high on the concrete wall. Every thing worked fine for aprox 1 month, until the tiger loop started screaming like a stuck pig. The installer replaced the tiger with a new one. That one worked for aprox 3 months then started to scream. He claims everything is installed correctly and has no idea what is going on?? I am on my third tiger loop at this point. Any help would be apprecitated.

Thank You
Kevin

tiger loop

I use tiger loops when need be i've rarely have had one go bad i usually mount them within 2 to 3 ft away from the burner with no check valves in the supply from the tank only a firematic and a general filter i usually use stell braded fuel lines . Are all your fuel lines done with flare fitting and has your mech install a 1/4 tee on the suction line before the tiger loop to see how much vacume he's pulling also check the burners suction press i'll post you a picture of one i installed peace and good luck clammy PS in the photo i abanded the old buried oil lines ran a 1/2 od supply line donw to the tiger loop ,the tank is bured and about 15 ft away have heard a peep good luck

so why?

why are you bothering with the tiger loop? If the tank is on the same level of the boiler and only 20 ft away why not just run a single line to the burner and be done with it....IMHO...:)

What type fuel pump are you running ? Is it a two stage or B pump ?

Tiger loop's

with overhead lines should be quiet. If you can get from the tank to the burner without the lines being in the way they should be on the ground off the bottom with the filter at the tank, if not you should still run it off the bottom with the filter at the tank, the oil filter is always before the Tiger Loop, that line should go into the center of the Tiger loop. Then the two lines coming in and out of the pump are attached to the Tiger Loop with the arrows showing the flow direction, You should never hard staple oil lines to beams in the house, you just made a big speaker, they need to be loose mounted in rubber or insulation.

It sounds like something is piped wrong like the filter is on the pump. Good Luck

Tiger loop

You should check the inlet port of the tiger loop. There is a screen in the inlet. You did not mention if there is a filter before the tiger loop. Is the tiger loop failing after each oil delivery?. You now have a basement tank, I would either run a return line back to the tank if you want to keep it overhead,or if possible make it gravity feed single line from the bottom. Don't forget to install an OSV valve with a filter before it if you run the line from the bottom.
