tips for instlation

installing donut in cast iron hub with 4 in pvc
Asked by: hank342
Thoroughly clean the interior of the bell into which you are installing this, place the donut inside the bell and be sure it is seated to the shoulder of the donut, measure from bottom of shoulder to bottom of inside of donut and transfer this measurement to a mark on your PVC pipe, grease inside of donut with appropriate lube, bevel the end of your PVC to a gradual end, about a 30 degree angle but not a long bevel, generously lube the end at bevel with appropriate grease, place beveled end of pipe into previously installed donut and force into same until you feel it hit bottom and previously marked point is approximately even with shoulder of donut. If you have difficulty getting the PVC to seat properly a bar for prying or a sledge hammer for striking may be used on the end of the PVC pipe with a block of wood over that end to protect it. I believe if you search on Youtube they will have a clip of this procedure. Hope this helps someone.
