Great Video, I have a 2-story house that I'm installing a Navian 240a tankless water heater in and the cross over valve looks like the best option for me to go with because the house only has 4 bathrooms, and the furthest bathroom is on the first floor and would be a pain to run a line to.
So glad to come across your video. The explanation & visual hookup of the crossover valve was great. It would be great if you answered some of the posted questions, as some of them are the same ones I have.
I have tankless water heater which needs minimum of 0.GPM to get triggered. What pump should i get? Got Water heater in basement, powder room at ground level, 2 full washrooms upper level, with no dedicated return line for hot water. 2000sqt townhome.
What I dont understand is, on a retrofit. How can adding a crossover for the farthest sink, affect the other sinks on another level the same distance away. Example. Upstairs in my house, the farthest sink away is the kitchen. Downstairs, its a bathroom. So how can adding one of these make hot water arrive faster at 2 separate locations? And as well, do the same for other fixtures in the house. I have tankless as well, I dont want my tankless system to always be firing to have an endless loop of hot water running back and forth in the lines all day and night. And I dont want hot water at my kitchen since, since there a T that goes to my fridge to make ice. Every line for hot and cold are seperated in my house from a Hot and cold manifold with each line having its own shut off. So I dont see why having something at a far fixture will give me hot water instantly at every tap or tub. Unless I am missing something completely.
@aljay2955 I think in the long run, its going to stay the way it is. I cant have a return line, and like you said, Ill save on water, and waste money on natural gas and electrical. Be nice if it wasnt PEX lines as they lose heat a lot faster than copper. Kitchen sink takes awhile, but its for washing dishes mostly anyway, so really you turn it on and let it run until its filled. Convenience is nice, but I grew up having to heat water on a wood stove, this sort of thing is so minor, unless it cost me like $50 to solve the problem, seems to be a lot of work and hassle.

Simple but great explanation of the subject. Finally I fully understand the process. Thank you so much it’s appreciated!!!

Can I put more than 1 bypass valves on different areas on my home?
i will use a crossover valve, which pump should i buy? where to install it, near the sink or near the heater?
I would like to know this too.
The pump is installed in the waterline of the water heater.
i wonder if adding an additional crossover valve would help with a larger home situation??
Yes it does. But your cold is always barely cool.
So what are the cons and benefits of PVC vs ABS piping?
