If this setup is to relieve pressure it's probably not a good idea to put that ball valve on it.

Brass ball valves aren't usually rated for hydraulic pressures.

Can't really tell from the picture but it looks like you have Teflon tape on the threads. Teflon tape won't hold up too long before it starts weeping oil.

I agree and yes that is Teflon tape. My purpose was to temporarily use it without the lift raising. The ball valve is always open so there is very little pressure and I am not running the system dry as recommended not too. If I close the valve, the lift will raise, so it does allow me to "test" the status of my stuck valve since I am hoping (more like praying) it will release and I will not have do the repair. This allows me to monitor for a while.

That said, your points are well taken. Thanks.
