Honeywell MZV520-RP Replacement Operator for MZ Series - Do I have to drain the system to replace my old valve?

This is just the operator and does not include the valve. If the value is ok and just the operator has failed, then no need to drain the system. Just swap the wires one for one with the old operator, unscrew the old operator from the valve. And install the new operator and adjust so the pointer is over the red dot, the included instructions provides greater detail on this step.

Yes it is. For the record, I"m still using my system at our vacation home. I purchased 2 units and they have worked as billed. I did have a problem with an extra valve but am only using 6 zones. I purchases 4 extra valves so I could use 8 zones if needed. So you may want to pick up a spare. Other than that the system works well.

You need both a diverted valve and a temperature control valve. That is two different valves that need to be plumbed correctly.

They just want you hooking it up to the backup one is all, the pipe that goes to a 45 to the main discharge. I did exactly what you're asking, put check valves right after it just like how you hookup a Watchdog battery system. If that's what you have right Now like I had. I took that 600 piece garbage out. This water backup one works awesome! Worth every penny, and it's 1/5 thr Price of the Best Watchdog Battery System. Another suggestion is I used those rubber inch & half elbows with hose clamps on each instead of using PVC elbows. Worked great for me and it's not nearly as Rigid. Google this also & click images, youtube video is also good Have a Great Christmas

I'm not a plumber, just a regular home owner. This Zone Valve IS ONLY a replacement for a zone heating system that is ALREADY using these valves! If you're adding zones to an existing boiler heating system, you MUST consult a plumber (and possibly an electrician) to set this up.

Sorry. I have not had to replace the valve yet. I ordered it as a "just in case".

As long as the old one is 110 volts AC, any intermittent duty water valve will do the job. Both parts look exactly the same, but there may be minor differences that might require a fitting adapter or some modification to the mounting bracket. Any differences in the two should be easy to get around.

I can't remember what model we replaced, but this went in super easy. We MAY have needed an adapter for the hose to valve, but I don't think so.

I just hooked up the wires from my old system to my new one and it worked just fine. My control valves are Orbit, but wiring works the same in every system I know of.

I put one in a Porter Cable. It was easy to install and much easier to use than the valve than came with it. Wish I knew if it fit your unit but I don't.

No, it is not. This is just a basic on/off valve on both the hot and cold side like all valves used to be. I am not sure it would meet code on a new installation. It was perfect for us, however, in that it was a direct replacement so we did not have to alter a bunch of existing plumbing.

When I had my filter replaced with the same model filter, I used the multiport valve from my old filter and it worked perfectly. The old valve fit the new filter with no problem.

I could be a replacement for an earlier model. Go to Honeywell and put in the model you have and you should be able to cross reference it.

None. I just unhooked the old one, connected the new one. Left faucet open for a bit, shut if off and I was done. It is working perfectly. Lots of pressure. If you let it completely empty every so often it will allow the bladder to last longer.
