This is a centrifugal pump, and I think the impeller is bronze. Once I have the pump out I will open it up and see if it can be rebuilt.<br /><br />What I did not want to do, however, in this freezing weather, was spend an hour under the bus getting the pump out just to look at it, which would probably be another hour, and then have to reinstall it, still defunct, while we wait for the correct parts.<br /><br />By having a whole new pump sent, I can be sure the system will be working after only one miserable session under the bus. If the old one can be rebuilt, we'll have a spare, which after this incident does not seem like a bad idea.<br /><br />My bigger concern is why it failed. These pumps can not be run dry, and the original installers went through three pumps before they figured out how to get all the air out of the system. Even though the pump is at the lowest point, apparently once a large air bubble reaches it, it will destroy itself before pulling any more fluid into the impeller.<br /><br />Once I have the new pump in place I think I am going to drive a while before starting it up, to see if that will move any air I introduce back up to the top of the system.Seanhttps://www.blogger.com/profile/17930398671280529448noreply@blogger.comtag:blogger.com,1999:blog-6208406.post-84734221511004935462011-02-03T11:27:11.338-05:002011-02-03T11:27:11.338-05:00could the blade be bad or the o rings broken? seem...could the blade be bad or the o rings broken? seems like you can fix it yourself, as you seem to be able to fix everything else.i know how it is as i ran out of propane in November in upstate ny, geni is propane and heat was propane.got a webasto at3500 and it will not work so i sent it to a buddy in Germany to fix it.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6208406.post-1502131956190811142011-02-03T09:28:37.434-05:002011-02-03T09:28:37.434-05:00Love the pictures of the animals ... sorry to hear...Love the pictures of the animals ... sorry to hear about your Webasto. I never even knew about a Webasto until your blog. I think that just shows how electric dependent other rigs have become.BaritoneJPhttps://www.blogger.com/profile/10006180379682825855noreply@blogger.comtag:blogger.com,1999:blog-6208406.post-1313337617315299172011-02-03T08:03:51.181-05:002011-02-03T08:03:51.181-05:00In very non-engineer terms...Bummer!
