You can't see the check valve because it's built into the recirculating pump

With someone who only has 3 subscribers, who are you to talk? I can sweat pipe, propress pipe, and megapress pipe. When it come to plumbing engineering and plumbing services, with over 30 years of experience, I am the plumbing authority. Maybe you should keep quiet and keep learning if you want to learn more. FYI, it's called sweating pipe, not soldering pipe.

The homeowner said he'll take care of the insulation. It took less than 2 hours to do the installation. Now he gets hot water at the showers that are far away unless than it 5 seconds.

You can use vinegar or "Haymaker" De-Scaling solution to clean the Tankless Water Heater. After De-Scaling, flush out the cleaning solution before turning back on the water valve.

Use Haymaker De-Scaling solution to clean out your Tankless Water Heater. Flush out solution after.

It's a Grundfos RCP96 KIT that includes a built-in check valve, flanges, 3/4" valves and timer. Cost about $800. And they say it could be installed indoors or outdoors. I buy these pumps from Ferguson pipe and supply. They always make sure to give me the right pump. This pump works with Tankless Water Heaters. I've been buying these pumps for over 30 years. I think I know which pumps to buy. Thanks for your comment though.

@@richyyaz lol I buy from them too. That's good to know. I had to buy from a company in California. Good work though.

Ferguson is my LAST resort! They think they're shit is gold compared to all the other suppliers, and if they pull your order amd you don't check it before you leave, 9 out of 10 times your going back because somethings wrong. I've installed dozens of those grundfos pumps on different tankless also. The right pump does work.

@@nickmac3426 I had to find a private company out of California to get the right one. The standard one from depot says in their literature "not for tankless". Sounds like we go to the same Ferguson LOL yeah they can be very frustrating I check every time before I leave

This toilet is a one piece Toilet, so it's different than a 2-piece toilet that hasn't tank attached to the bowl.

Los Angeles

I think I snaked it a couple times.

No

They do if you buy one with it. This one didn't have one.

@@richyyaz thanks for getting back to me. I really appreciate it!

@@paulcullotta4347 You're welcome

How did you know? Lol.

I know that and that was one of the things I mentioned to the home owner. I also told him he needs a hot water expansion tank. He just wanted me to install the relief valve Drain for now. I went back later to do other work.

Matter*

That's is fake mm2 u can buy fits its called "zyleaks mm2"

A $150 per person.

When I unplugged the unit and plug it back in, that's a reset.

It's 10 years old.

A Storage Tank Water Heater builds up minerals

Sweat fittings are cheaper

I usually don't use a Propess when I'm installing a hose bibb or a purge valve. People can yank on the hose and loosen the pressed joint. It's happened before.

Yes and yes. You know your stuff. Do you work in the field?

Good question. This was in 2021. In the year 2021 we still wearing masks because of Covid-19.

Yes

Thinking the same thing

The host bib goes after the pump to purge the air out so the pump will be pumping only water and not air.

And the check valve on the cold water prevents hot water from going in the cold water we can’t see one unless its inside

@@javierprado6545 The check valve is built into the $850 pump. This pump came with two valves and a check valve assembled.

​@@richyyaz The built in check on the pump doesn't stop hot water from feeding into the cold side where you tied in! Like they say " cheap work isn't good and good work isn't cheap."

I ended up using a grinder to start the cut and a Carbide Sawzall blade to finish the cut.

The Diablo blade is incredible at cutting cast iron, I was amazed how fast it went through the pipe.@@richyyaz
