No problem. The IHS Sight Tube Kit can be installed on the same port as your outlet valve with the addition of two options:

1.  A tee fitting and nipple: This splits the single outlet on your kettle into two ports as shown in the photo below.





2. The Shut-Off Valve:  When using the Hop Stopper or other dip tube arrangement, draining of the vessel requires a siphon once the liquid level falls below the level of the outlet port.  With the IHS Sight Tube in place, the open end allows air to be drawn into the liquid stream when the liquid falls to this level.  To prevent this, a Shut-Off Valve is installed on the open end of the Sight Tube which can be closed during draining to preserve the siphon.  See the photo below.
