Very cool site. Thanks! Had not seen/heard of it before.

I'm trying to plan out my renos with the least amount of destructive force to the rest of the house, although how feasible that will be, I'm not quite sure. I'll have to see about sprinkling the...

Actually - not my call. From the feedback I've gotten from the city, it's a requirement for all new homes and/or extensions to homes to have fire suppression sprinklers added to any new...

I'm not sure of my exact static pressure, but I believe it to be around 80psi. I need to double check. I don't expect it to change if/when forced to change my main as it would still be drawing from...

That was pretty much my thought process and expectation as well. I had not considered the issue with the cleanout however.

Does anyone know the requirements for max turns before a cleanout? (I...

Hi,

My wife wants a new master-bathroom with a kick ass shower. ie: multi-head body sprays, ceiling mounted rain-head, pulsating jets, etc. (She had even tossed in the term steam but I think I...

Hi,

This may be code/region dependent, but I was wondering if there was a maximum length/distance (logically or otherwise) for a bathroom DWV line. I'm looking to add a half storey to the house,...

Why not use the heating elements in the tank to keep the heat in the tank constant, instead of refeeding it back to the tankless? Additionally, if refeeding it back to the tankless, it would likely...

Interesting concept, although I don't really see how this "buffer" would work too well. In a standard setup (ie: no tankless involved), when I turn on a hot water faucet, the pressure from the...

Hi,

I've got a 60gal hot water tank with a gravity recirc loop that is working well. My home currently has 3 full baths and 1 half-bath. I am now looking to add an extension to my home that will...

Thanks for the info. I'm not 100% clear on your statement though; please let me know if I understood you right. If you have just the bathroom hot (nothing else in the house) running, it is hotter...

Do you have a valve on your return line that you can shut and see what kind of temp differential you get with or without it at the faucet?

Thanks,
Eric

Ok - replumbed - again. This time put the check valve horizontal and rotated it a little (see picture). I put in a 2' level at the vertical to show the slope. The check valve allows water to flow...

Thanks for the explanation. I added a picture to my above post indicating how I am set up around the HW tank. I had to replumb my pex a little to put the valve in at 45dev, but at least now I can...

Thanks for all the help HJ. I'll get a picture posted later today. I guess I just don't understand the physics of a gravity system. After trying the Sharkbite and seeing that fail, your help has...

Ok - so now I'm even more confused. I picked up a 3/4" Watts tee swing check valve and a couple of 45s. Before I installed it, I did a quick test with a garden hose to see how much pressure it...

Good point; had forgotten that the pressure on the faucet side of the checkvalve would drop since the tap would be open thereby allowing the checkvalve to remain closed.


Not quite sure if your...

Thanks for the tips HJ. Have a few questions based on your response though:


Yes - return line is flowing downward. If the Swing check is installed vertically, the flap would be essentially be...

HJ mentioned that he has installed them at an angle; any idea what the max angle would be? Is 45deg too much? Putting it at horizontal would require a bunch of extra effort to make it a nice...

I am using a SharkBite check valve, and I'm not 100% sure, but I believe that a SharkBite checkvalve is a spring valve. That's what you get for being lazy. I had both in my hands, and figured for...

Hi,

I just tried putting in a single branch gravity recirculation loop and am running into a really strange problem. I've got a bottom feed hot water tank (ie: the cold water enters at the...

Thanks for the tip, but can you please elaborate, or point me to docs that explain this better? Why the need for a balancing/check valve on each one? If I were to place a recirc pump on the primary...

Hi,

I've been reading up on recirc loops and am trying to understand which is more efficient for a residential use. Given a setup in which there is a dedicated hot-water return line, I realize...

This might sound like a silly question, but it looks like this would have to be connected directly to the water line. Which means no manual shutoff valves? I don't get it; there is no way to...

Hi,

I'm plumbing my laundry room, and thought it would be prudent to put in some automatic shutoff valves in case of hose or machine leak in the room. I figured a water sensor at the baseboard...
