How much air into Townshend 3-D Seismic Sink

Thanks for responding to my post. Do you think this is an excellent isolation platform? The pump that came with my Seismic sink isn't the original but a bike pump. When unscrewing the pump from the Seismic Sink valve after pumping up the air bladder all the air comes out of the sink. Do you know of a way I can get around this problem, possibly an air pump that has a quick release instead of the screw-on type? Thanks.

I have several sinks. When you speak about the air coming out...what comes to mind is that the rubber "seal" inside the sink's valve is either damaged or "out of place somehow. This has happened to me before. I think I just kept playing with airing it up and releasing the air. Hopefully you are not using a needle on the pump. You could try to suck out on the pump and then remove the pump and this may place the valve in the right location. The screw on type is the only way to go. As far as the amount of air ... you should place the component on the sink and inflate to where there there is 1/8" free movement when you squeeze each corner.

One more thing... if you have the kind with a wall wart (powered) you pump slowly until "exactly when the light stops flashing". Periodically all sinks will need inflation just like your car tires.
