are there built-in check valves?

It is just like your faucet valve. Close, open, adjust to make warmer or colder. Works great.

I don't think so, it is just a mixer. It would have been bigger if it had them.

The valve is not included. Please see the specs for the correct valve model.

Mine came with 2 check valves. One for each centrifugal pump. Otherwise with only a single pump running it would be back flowing out the other pump. A third check valve in the line past these can't hurt but shouldn't be necessary...

my previous post about check valve, might be in pump internally and not separate unit

It's a three way valve!!It's not a check valve, but I guess you could use it with a secondary discharge pipe so you can manually switch the location of the discharge.

No. You'd have to get a separate valve for that. I've seen them for $10 at hardware stores, very small & push-button operation.

I have one of these and a bigger one that is for up to 40 gallon tanks and if I remember correctly they both came with the pump and a check valve....it has been quite a while since I got this particular pump though

I don't know what you mean about the check valve...what you see in the picture is what you get...It works perfect....

There's no flow restrictor or check valve it's simply open and has a small hole I suppose for extra air venting during pouring.

It has a check valve but that's it. It is NOT a Schrader Valve like you have on your tires.

Doesn't come with manual release valves. That is the only gripe I have otherwise.

There is no valve. The bittle is sturdy, and nicely made.However, it is very large. I didnt see that until actually using it. It makes it hard to handle.

i believe there was an option upon ordering for the type of valve one used. it's good for the price, the separating tools are flimsy, i bought a set on line at same order with the kit, and sure nuff, one of them broke. not uncommon. sorry couldn't help with the pump question any more.

There is no valve per say but I do believe they are interchangeable, mine work with other sizes.

- No check valve included (cannot recommend one as I just installed the pump into the existing circuit)- I don't think this is the correct pump for an irrigation system- We use if for our house water and it definitely needs to be used with a pressure tank
