Internal Circ pump Burnham Revolution RV5SL-L2

mrbostnmrbostn Member Posts: 4
I have a serious leak coming form my internal circ pump on my furnace. Unfortunately for me the install kiddie cornered it. I have 4 inches on the left 3 on the back.

Anyway I'd rather not get a whole new boiler for a crappy internal circ pump failure.

The water is leaking from where the wiring is on the left side. I want to replace either the cartridge (if possible) or the entire pump.

The current pump is black so it an OEM. I also read that it's an oem Taco 007 but I want to find the model The Burnham manual states a Position 4 pump? Is that speed?

Any tips are greatly appreciated. BTW I've contacted 5 plumbers in the area on 1 answere. They cam and wanted only to replace the furnace.

    Here's the exact wording from the manual Circulator, Taco 007F, Position 4

    Can someone point me to that type of circ so I can buy one. Thank you

    I believe it has a tekmar variable speed control on it A fixed speed 007 should work

    Thank you for the reply I'm not a plumber but I don't see anything like a tekmar control unit on anything.
    I have the Honeywell VS3000 if that means anything.

    Also I don't know how to size it I have Taco 007-f5's for each zone. but the size of those are smaller than the internal circ pump.

    Also there are no additional "switches" or controls on the internal circ pump, Just the pump and the power wires.
