Bumping this back up. I did have an elbow within 2 inches of the cold inlet, and read that could cause check valve chatter. I replumbed it now and I don't have an elbow closer than 6 inches from either the hot or cold inlets where the check valves are. On the mixed outlet, I do have a 90...

Im having a hard time following your drawing. Is the bottom part upside down? I'd suggest any time you have a major change in direction to try to have a cleanout, so use a tee wye and put a cleanout plug in it. Also, as to slope, 4" pipe can be as little as 1/8". I wouldn't use more than 1/4"...

I've got a permeate pump and am using the pentek pentair 1:1 membrane and my rejection rate is amazing. I just tested it a couple weeks ago...I do it every january. My raw water has a TDS of 65, after the system its 2. This is with a membrane that has passed 2 years of service. Lowering the...

If it helps, its the model with the unions which has integrated check valves on the hot and cold inlets.

So sorry to hear of this. This forum has done a lot for me, and I enjoyed seeing Terry's posts. His death is a real loss, and I feel sorry for what his family is going through. Best wishes.

Just installed a thermostatic mixing valve, the Honeywell AM101-USTG-1LF. It chatters often when water is being called for, although not all the time. Its not super loud, you can only hear it standing in front of it. Just want to make sure this is normal, I can't seem to find any info on this.

For residential I like Siemens copper bus. QO is good too, but the tubs tend to be a little small for my liking. For commercial I like Square D QOB (bolt-on QO) for the small stuff, I-Line for the big stuff.

Regardless, why not install one? They arent super expensive.

Gas range does not need a dedicated circuit, just a hood if it is cord and plug connected. Reasoning was the NEC wanted to make it easier to convert a regular hood to a microwave hood later which draws a much higher load. I know you have a separate microwave already, but the code doesn't care...

You're gonna need to be a little more specific. Is this an electric water heater? If so then in the wiring compartment there should be a green ground screw, or a pigtail, that you would tie to the ground present in your non metalic cable, or metal clad cable, or whatever the wire type is. if...

A fan with a remote doesn't usually need the extra wire. Extra wire running back to the switch is for a fan without a remote. Remote receiver, provided it lives inside the fan and/or fan canopy/junction box will just need the 'hot all the time' wire.

Is the range hood going to be hard wired or cord and plug connected? Remember if it has a cord and plug, it is required to be on a dedicated branch circuit and can't be shared with the cooktop. Also, check the single wall oven. Many single wall ovens only need a 20A OCPD and 12AWG wire. As to...

Parents have an existing 180,000BTU Rinnai RL75 with a single bathtub/shower combo. House is located in New England with estimated incoming water temp of about 45 degrees. Heater has been doing the job just fine. At Delta T of 60 degrees (to get to 105 degree shower temp), estimating their...

Yes you can. I like sharkbites better, but agree with Dittohead that if you piping is coming from above or below, the 90 degree is the only way to fly.

I am at about a tenth of your values for Iron and Manganese, although it varies. My ORP is pretty high. My water runs clear as well. I am not a chemist, there are people on here much smarter than I am that may be able to better answer your pH question, but most of the medias advertise that they...
