    Default Oil tank filter

    I have a Westwood filter on my oil tank. Seems to be leaking a little. Does this happen if the filter gets old/clogged? I am sure I could change it myself. I believe there is a removable element inside the container? Does it screw off? Also it seems like there might be 2 shutoff valves in the line? Actually, it looks like it's coming out the top. There is a screw with a jam nut,is that a bleeder screw?

    frank,

    Could you post a photo of Westwood filter and the adjacent piping with the shutoff valves; there are several models of Westwood filters if you can get the model # from the filter housing & post it so we can get a good idea of what you have, as well as different valves near the boiler and near the oil tank---the important thing is to MAKE SURE YOU HAVE SHUT OFF THE OIL TANK OIL SUPPLY, or you'll have fuel oil all over the cellar floor.

    The shut-off valve for the oil tank should be the first valve that you see at the base of the oil tank as the copper or steel line comes out of the oil tank---however, sometimes the shutoff valve is located closer to the boiler/furnace, just before the fuel filter housing.

    Does any of the filters/housing look like any on the 1st site below:

    The 2nd diagram entitled "Fill and Vent Piping" at the 2nd site below illustrates the shutoff valve as the supply pipe comes out of the oil tank, and then goes into the oil filter/housing---the shutoff valve HAS TO BE CLOSED before you loosen the oil filter housing to prevent oil spillage---is this how your oil tank/shutoff valve arrangement looks???

    If there is a nut at the top of the fuel filter housing, like most Westwood filter assemblies, just turning the nut CLOCKWISE slightly should tighten the assembly & stop the leak.

    I tried posting a picture, doesn't seem to work. This is the one I have, although it may be hard to see the top. Mine has what seems to be a threaded rod with a screw slot in it, and a nut that goes on it, almost looks like a "jam nut". http://cache.vendaria.com/integratio..._uid_202274784

    frank,

    Yes, the F80 is a very typical fuel oil filter housing that has been around for many decades---the top nut is turned clockwise to tighten the top nut and compress the two halves of the fuel filter housing together---there is a long metal center post welded to the bottom of the fuel filter housing bowl--the tighter you turn the top nut, the tighter the halves compress to stop any oil leaks---unless something else is going on---1) there is usually a little black neoprene/rubber gasket that seals the inside top cover of the F80 housing to the bottom part of the F80 housing---this can sometimes leak by getting misaligned, or broken/torn; the gasket is always replaced when a new F80 filter is installed; 2) on rare occasions the shaft near the top nut gets worn, in which case a small tight-fitting neoprene/rubber grommet can be placed between the nut and the top housing of the filter housing; or a new F80 housing can be purchased, but you can usually get the existing F80 to be leakproof by trying the suggested modifications.

    These filter & gasket products may be sold at HD/Lowe's---check by phone first; if not, consult the Yellow Pages under "Heating Equipment--Parts & Equipment for the nearest Heating equipment supply house in your area---you need the new filter AND the neoprene gasket.

    You still haven't answered my question as to your oil tank/shutoff valve/oil filter housing setup: referring again to the inspectapedia site, scroll down to view the 2nd diagram entitled "Fill & Vent Piping" that shows an oil tank, a SHUTOFF VALVE, and a fuel filter housing---is this the setup you have on YOUR system??

    As noted before, YOU HAVE TO turn the faucet-like knob on the shutoff valve OFF (clockwise), and the shufoff has to be BEFORE (closer to) the oil tank, so that when you open the fuel filter housing to change filters you don't spill any oil on the floor.

    this morning I tried to post a picture from my Flickr account, it said something about waiting to be approved by a moderator? I don't know how long that could take.http://www.flickr.com/photos/10004922@N08/8443907661/[/IMG]
