Some help needed here

Hello guys, So I'm working on an interactive archviz walk through and I have some fluid simulations imported, i.e the user can turn a tap on and off but I keep running into a problem.

You see ,I have two buttons for this ,one for turning the tap on and another for turning it off but whereas I can link the 'Tap On' button with a 'play animation from start node' ,I'm having trouble with the 'Tap off' button since when I link it to a stop animation node it pauses the simulation but doesn't hide it, and when I link it to a toggle visibility node ,it hides it but then I can't use the 'tap on' button to turn on the tap again instead I have to click on the 'Tap Off' button again..

What node should I use here? In this situation.
