Thank you for your quick reply. I got 3 zones and both the supply and returns are 3/4" so I would probably reduce to 1" manifold and branch out in 3/4". What do you think?
Good morning, thank you for posting these videos and sharing your knowledge. I have a question: What size are the inlet and outlet of the manifold and what type of adapter (reducer?) you use to connect to the supply and return. Second, If I were to build the manifold myself (pretty expensive I would say), what pipe diameter is the horizontal run? Thank you n advance for your time.
@antoniorestrepo4299 Hello, the Navien manifold is 1½". Depending on how many zones you have, I leave it 1½ or reduce it down to 1¼. The horizontal runs it depends on the zone. Usually they are ¾".
I’m genuinely curious. Why would you put the make up water plumbed to the combo boiler between the fill valve and the back flow? Does this help fill the tank inside the combo boiler quicker because it’s full house pressure? Wouldn’t this over pressurize the boiler and pop the t&p? Thoughts?
@BeeBombard The fill going directly into the unit is controlled by the unit automatically. The one installed after the PRV is for services and bleeding.
@@PrecisionDavePlumbingMore The reason I don’t like tankless is from a financial and hassle point of view. The tankless machines have such a high up front cost that it would have to last twice as long as a tank to be worth its cost. A tanked gas water heater can often last over ten years without the owner giving a second of thought to it. With tankless you really have to give it good maintenance for it to even have a chance at lasting ten years. As we know homeowners aren’t going to like the idea that they have to now maintain an appliance that was previously maintenance free. Say it isn’t maintained and fails after seven years. Then the homeowner is hit with another large up front fee and the chances of ever saving a dime are completely gone. As time goes on and technology gets better tankless may become a good option but as of now you’re way better off with a standard tank or boiler. As a final thought the newer tanked gas water heaters are so efficient already with the added insulation that a tankless isn’t going to save much on a gas bill. Even if it does save a few bucks, it will never make up for the initial price and added maintenance costs.
NJ & NYC LMP here. Beautiful job man & still nice to see there's pride in the industry 💪🏼👍🏼
I appreciate that!
Excellent video!
Thank you
Amazing job
Thank you
Nice install.
Thank you

@@antoniorestrepo4299 No manifold in 1¼" and branch off with ¾" for each zone.
She's a beaut
Thank you, I appreciate it

what size copper was used in this build, for the manifolds and to supply each pump?
1½" L copper for the main and 4 zones where ¾" and one was 1".
R those appolo ball values? If so they r one of the best in the industry!
Unfortunately, there are not Appolo valves, but they are amazing valves. Thanks for watching
That’s super clean and nice work. The soldering is amazing. I don’t like combi boilers or tankless in general but nice job on that install.
Thank you, solder for life. Curious why you dont like tankless?
