Pump quit working
« on: October 26, 2017, 04:05:12 PM »

Wife called today while I was at work and said the house was cooling down and duct blowers running continuous. I had her go out and read the temp for me on the boiler. It was 180. Oh no I said. New it was something costly. My question is this boiler had a Wilo on it went they installed and it's a small one(10gpm and 10 feet high capable.) I really don't know why I hadn't already had trouble. The run is only 75 feet however it travels up the brick wall on outside the house and through the attic to the air handlers. It then  y's off and travels through separate heat exchangers. What would you recommend for pumps as far as size, brand, etc. I called the company I bought the boiler from and they did it should at least be a 25-30gpm. I wish they would have told me 3 years ago when I bought it new. Probably shouldn't have lasted this long. The reason for the attic run is there is no crawl space or basement  in my house. Whole house sits on concrete slab. All 5400 sqft. All ducts and air handlers are in attic.

Without more info a Grunfos 15-58 on high might handle it, a Grunfos 26-99 definitely will.

How much and what size pipe in the house? Total length of the entire loop from boiler to furthest point and back would be helpful. How many exchangers? I'm pretty fond of the Grundfos 26-99 on all boiler loops over 100 feet round trip. Amp draw is almost nothing on low speed, and if you need more flow there's plenty available.

About 40 feet of 1" pex so inside loop is 80 outside is about the same. So 160 foot loop. My ceiling are all 11 feet so the water claims around 13 feet before it goes through the soffit.

Use the taco TD10 to size your pump correctly. Just google taco td10. It walks you step by step how to siZe a pump correctly. You will learn how your system and piping works too. Just FYI, you can't push more than 7-8 gpm through 1 inch pex.

Somebody really needs to make an app for that, drop down box for pipe size, pipe type, water temp, etc etc. Then go all third party and have multiple brands to select from. I have a Taco Delta T pump on my house loop, wouldn’t be my first choice if B&G or Grunfos offered a Delta T.

There are no retail stores in the area I live in for me to go and look and listen to someone offer suggestions on Boiler parts. That's where you guys come in. I will be ordering this new pump over Internet and do t won't to make a mistake that will bite me for a long time. I was hoping to find one in the 150.00 range.

There seems to be two die groups of pumps -sorta. The 15-58, NRF-22 B&G,  0015 taco, etc..less than $100.

Then you have the 26-99, 0011, etc. in the $200 range. Guaranteed to blow out air.
The B&G NRF-25 is sti under a hundred and gives a bit more velocity to clean out air. Probably what I'd use but I always plumb in a tee into the domestic water to purge air thoroughly before starting up.

They're usually almost double that. I have bought my last few from that dude on eBay for 150 also, and they've come in factory packaging and work well so far. You'll be much happier with some flow over what you had before. Keep us informed when it's installed!

Will I need the flow check? Notice on my eBay account it said with flow check. What is flow check? I assume by reading other post I can remove it if it's not needed. Problem is I don't know if I will or not.

The flow check is a check valve, in your case since your pumping up to the attic it will keep the water in the supply side from draining back into the stove when the pump is off.

I don't think he needs a flow check as it can't flow back without a leak to allow air in to break the vacuum right? I thought the flow check was to prevent flow when it's teed off or such like where another pump creates flow.

 In the case of a leak it would still flow back to the furnace in the return line and empty the attic. There is no reason for a check in the primary pump. I don't like them in a pump just for the reason it's easy to air lock a pump. If you need a check to prevent 'ghost flow' you can put it down flow from the pump even on the return line and give some room for air to pass through the pump without locking in the pump. Anytime a line empties it must be replaced with air. If there is no place to get air water will stay in the pipe no matter how high it is.

  Got a cummins right now that empties it's fuel back to the tank overnight and has to pump back up to start in the morning. I know there is a small leak somewhere I need to find.

I'm with those fellas^^^. It doesn't sound like a check is necessary for your application anyway, but the reason I always pull them out is that they tend to melt at 200* or so. Warm days certain boilers tend to overshoot a bit, especially P&M, and melt the checks in the pump and cause a no-flow condition eventually ruining the pump
