Can I do this and if so should I just buy different flanges than it came with or get a 1 1/4” male thread x 1” sweat ?
Hey everyone, first time posting here, so I would appreciate any help. We have a water heater and a Grunfos pump circulator. The circulator was old and died, so we got a new one. Upon installing it, it has been making a low humming/buzzing sound and I do not know how to fix it. I read it could be air in the system, so I flushed the water heater (I think properly) and it is still making noise. Any advice would be appreciated. The pump is a Grundfos UP15-29SU
Hi all,
I have a completely new heating system in a renovated apartment. The water leaves the water heater and is circulated by a pump to a radiator. The clicking/rattling in this video started after about two months of use. Any idea what could be causing it?

Thanks!
EDIT: Thanks, everyone! The installer is coming tomorrow to repair it.
Just bought a home that was built in 2007. The electrical components for the well burnt up a couple days ago and I had a repair person replace those and get our well pump back up and running. The well is also connected to two pressure tanks prior to coming into the home. There is a Taco 003 -b4 circulator pump connected to the water heater. Since the well issues, the Taco pump has been making noise when running and our water pressure is fluctuating sporadically. Do I need to replace the cartridge on the Taco pump or is our lowered water pressure caused by something else?
When the boiler reaches 180°F the boiler shuts down, then so does the circulator pump. The pump needs to run until the temperature is at what ever it needs to be. Why does it shut off and how do I get them to work? The boiler is a knight boiler hooked up to 15 thermostats which goes to one circuit board to turn the boiler on. When the boiler turns back on so does the pump. The system isn't a new installation so thats not the issue. To my knowledge the pumps need to run until the thermostats are satisfied. I don't have any pictures but when I can get some I will update yall.
I have a 25 year old boiler and I’d like advice on how to replace the circulator pump on it. It’s not getting any power anymore. I’ve bought a replacement part for it but I’m not sure how to remove the old pump and nervous with plumbing.
I’ve added some photos https://imgur.com/a/AhQyu5V/
First turn off the power.
Then I believe I should turn off the main water line to the boiler.
Then I should turn off the individual ball bearing valves that go to each zone.
Now I would be ready to turn open the drain valve and drain what water so I could replace the circulator pump.
Is this The right course of action? What’s the knob in the second photo.
New home owner and my house has an oil furnance with baseboard heat. Im trying to learn some more about my furnace. The furnace seems to be working just fine but ive noticed my circulator pump will continue to run after the post cycle. Ill hear a pretty audible buzz from the immersion box/hum from the pipe connected to the pump. Just wondering if anyone could maybe throw me some insight if something is wrong. I was thinking maybe the relay switch is faulty but i dont know much to begin with.
Hi all, Picked up a free spa, but the circulator pump is broken. Had a look inside and it's pretty rusted etc, tried cleaning it but no cigar. So I'm wondering my options, clearly wanting to spend as little as possible. Spa controller is a sp601, and it appears I can disable the circulator completely, although not sure what effect this will have. Additionally it appears I could swap the single speed main pump for a dual speed and forgo the circulator pump.
Pump wise it's a laing sm-959-nhw-26. Replacement wise it looks like a laing e10 is the direct replacement but keeping costs low would prefer not to spend ~$300. Looking at cheap chines options I could get something like one of these: https://www.ebay.com.au/itm/100W-3-Speed-Solar-Hot-Water-In-Line-Circulator-Pump1-5-Solar-Heating-Low-Noise-/192528119065?_trksid=p2349624.m46890.l49292
Flow rate seems a little low but same power specs and would probably do the trick? Otherwise anyone ever used a dishwasher circulator pump? Similar current, flow and temp rating and cheap as chips. Only thing I'm not sure about is lasting long term but as cheap as they are I don't think that'll be a massive issue.
Any thoughts would be greatly appreciated!
