Leaking Taco Zone Valve

One of my Taco zone valves (gold head) is leaking from what appears to be the gasket from the base unit to the head. Can this be repaired without soldering in a new valve (rebuild kit?). Can I do it without drraining down the system? I have a shutoff valve on the radiator side but not on the ciculator side of the valve.
Any help would sure be appreciated.
Thanks,
Joe

The only way you will be able to repair it is to cannibalize a brand new valve. The parts you need are not sold individually but if you buy the whole thing and use what you need, you will have a spare power head and save the labor cost of having someone replace the valve for you.

thanks for the advice. I picked up a unit at home depot and replaced everything minus the housing. Works fine and saved all the trouble of trying to solder in the unit in a very tight place.

leaking taco zone valve

Did you have to drain your system? I have the same exact problem and I bought the zone valve today but I'm trying to avoid draining the entire system. If anyone has any suggestions I'd appreciate it.

Yer gonna have to drain it... you can replace the powerhead without draining, but not the guts.

Look for valves that you can close to isolate as much of the piping as possible and only drain as much as you need to. The less fresh water you introduce to the system, the better.

All done

Thanks NJtrooper:

Drained the system and replaced guts and she's purring like a cat. Anyone know the shelf life of these Taco zone valves?

Mine were installed in 1985 and my feeling is that when one goes get ready to replace the other 8 zone valves.

Most of the valves I have seen fail were because someone overheated them during installation. If that is the case, they may all fain in succession. Maybe just the one you repaired got overheated and the rest will be fine. They seem to last hundreds of years. Exxagerating but longer than my career (30 years).

Taco leaking

HI,

My taco is leaking out of the base. I red above post and would like more information. Do you have to sweat a new base on or can you unscrew the four screws on top of the base and replace the inner workings? I can total isolate my valve from the rest of my system.

Thanks, David

No guarantee

You can probably get away without the soldering if you replace the parts. It is not a normal procedure but the parts have not changed over the years. Take off all water pressure and be careful as there may be spring pressure on the retaining plate. I don't remember.

Hey Ken,

Thanks for the quick reply. The taco in question was over heated last Christmas when the bowler make water valve was closed and I lost pressure in the system. My theory is that this zone was open when the loss of pressure and the boiler over heating occurred.

From looking at the schematic of the taco is does look like there is a spring in there being held down potentially by the top plate.

Thanks again, David

Hey Ken,

One more thing. What broke to cause it to leak? It did potential get overheated 8 months ago. The hole system was put in one year ago.

HI,

I got a new taco zone valve (had to order it b/c around here everybody carries honeywell not taco). I put the new low part in and yes you have to watch out for the spring when you undo the four screws on the base.

Thanks for all the help.
