What is meant by "See the links section of the device page for where to purchase a new pump"? Which device page on which website? Are you not able to just post the link? Which type/model of pump is required?

My son and I successfully replaced the pump, but it didn't go quite as easily as I'd thought. We could not get the hose that connects the boiler to the pump off. Thankfully, my clever son realized we could turn the portion of the pump that screws into the t-end to get the old pump off and new one on.....tricky, but doable. The new pump is a bit noisier than the last, but she pulls beautiful shots. Thanks so much for this guide!

Does anyone know the purpose of the hose that goes toward the back? not the one to the boiler but the other one that goes backward and down from the t-connector? it doesn't seem to be moving any water but the unit seems to work fine.

That's a return line I believe. So if there is water left it can drain back to the reservoir.
