@ June 26, 2013 1:15 AM in Help with finding an angle valve for Runtal radiatorsIt would be nice to know what Runtal recommends on how to install their radiators.
Don't they have any "solutions" on their website?
@ June 23, 2013 8:16 PM in Old style toilet flush valvesI think you nailed it on that refill supply hose shoved down the refill tube.
@ June 20, 2013 7:31 PM in Rat's NestFrank: Those relays control pumps in a 5-unit apartment building.
When I first saw this, I wanted to sell the owners a more modern pump controller, but after thinking about it, I don't believe it would be in their best interests since those relays and transformer are probably original equipment. The pumps are all original Grundfos as well.
@ June 17, 2013 12:07 PM in Old style toilet flush valvesDouble check that one-inch diameter refill tube. I've seen them corrode and leak above the threads.
More commonly, it's the tank ball not fitting the flush valve properly.
@ June 7, 2013 5:46 PM in Low water cutoff'sa pressure switch which is usually a separate device.
Personally, I don't like combination devices.
@ June 5, 2013 12:27 PM in Steam to hot water radiator conversion valvesthermostatic radiator valves? Try Danfoss.
I'd like to hear more about your steam to hot water conversion.
- Has the system been pressure tested for leaks?
- Are there room-by-room heat loss calculations and radiator output numbers to see how the radiators will perform?
I'm just curious because I've been tempted many times to do the same thing.
@ May 30, 2013 4:34 PM in MZ Boiler Knocking Noise Steam Venting Overheat?Is the steam coming out of the flue? Could be a bad heat exchanger, i.e. water leaking into the combustion chamber.
Knocking and high temperatures would indicate reduced or no flow through the heat exchanger, but the MZ has a flow switch that only allows the burner to fire when there's proper flow. I'd removed and clean the strainer, check the pump to make sure it's working and check the operation of the flow switch. I'd also open up and clean the heat exchanger and check for any leaks.
Do you have a technician that's familiar with Monitor boilers in your area?
@ May 12, 2013 12:49 PM in Hot water recirculation do they save money?it wastes energy. The electricity to power the circulator and the heat loss from the piping. But others would call it a convenience.
Most of my customers strongly dislike waiting for hot water and will gladly pay for the convenience of instant hot water.
@ May 4, 2013 9:14 AM in CVfor their Sentry valve:
@ May 1, 2013 9:19 PM in Honeywell Mixing Valvethey give you two extra ports - one for unmixed hot water (laundry, dishwasher, radiant to a heat exchanger, etc.) and another port for a recirculation loop return.
I saw this display on my suppliers counter on my way to the job where I needed one and even though I had two conventional mixing valves, I bought one for speed.
Here is the literature:
@ May 1, 2013 11:24 AM in Honeywell Mixing ValveI like the new Honeywell DirectConnect mixing valve kits. A real time saver!
@ April 28, 2013 12:16 PM in Remembering Gil Carlson.....and thank you Dan, for bringing him to us.
@ April 22, 2013 1:06 PM in Running A Gas Line UndergroundWe see a lot of PLEXCO out here and you can use either stab fittings or fusion for joining. I prefer fusion because the fused joint is stronger than the pipe itself and it's more resistant to age and chemical related deterioration.
My supplier rents me the machine and it's very easy to use.
@ April 15, 2013 12:36 AM in help with taco zvc 404use the Taco ZVC 404 for the radiant and a Taco SR501 for the radiators.
I think Steve's suggestion for a diagram is because of your last paragraph - it sounds as though you have a primary pump that needs to be on when a radiant zone calls for heat and somehow, that primary pump serves the radiators by itself. You might need to do some re-piping and/or add another pump for this to work properly.
@ April 5, 2013 9:55 PM in Taco VortexI'll have to second that, i.e. "I call BS"
What is a 1/2" NPT threaded rod? When you buy threaded rod, it's machine thread, not NPT. And like Rob, I tried the "jacking out" method with the same result. Jacking in would be a better description.
When I first started buying Vortec air eliminators, the attraction was interchangeable parts. If the Hy-Vent ever went bad, I could switch it out. Apparently, this is not so.
Factory changes in the sealing process would be appreciated. Caleffi has been my substitute even though I prefer to buy US made products.
@ March 31, 2013 4:15 PM in Threaded connectionsin the Bay Area sells all the usual stuff: Recorseal, Blue Magic, etc. The grey dope that you mention sounds like a specialty product.
If I have a difficult connection, say a large, pitted fitting where I have to start my piping or a European fitting that has no taper, I use Super Dope; it works anaerobically. I've tried it on new fittings with only hand tightening - no leaks!
@ March 31, 2013 4:01 PM in Pump for Washing machinesell this type of system:
The laundry tray acts as a reservoir since the pump is not powerful enough to keep up with the washing machine.
I have a Myers pump attached to my laundry tray in the basement and it works extremely well.
@ March 22, 2013 8:53 PM in reliable Low cost thermostat with remote sensorWe did a job in San Francisco in 2008, a large house with over 20 zones. They didn't want to see thermostats in the rooms and we ended up using what you describe. Here are the parts we used:
8818 distribution panel
8825 hub (distribution panel)
8051 flush mount sensors (L40-491)
As you can see, we also used a Taco zone valve controller.
