Hi Radar, you mention about changing the electric motor, so that's possiblle then, are these normally held as spares in CH retailers, what your saying is I dont have to change the valve just the electric motor?
Plumbbob - Thanks for the very useful information. I have exercised the offending valve with the power off and it appears to have recovered and is working OK tonight. So I will keep an eye on it for the time being and will look to replace in the NY. Thanks again for the good info and rapid reply rgkl
[size=18]The BGMVSP2 has an indicator lever with 2 positions A-B, can I assume this is an indication of open/close is this correct? if so which is which? If the indidcation is between these 2 positions does it mean the valve is jammed or is it a "no power" indication?[/size]
