Can it be under pressure before the float valve.

I would suspect it would leak, as the seals on the drain tap and valve, and on the hose connectors, are probably not designed to cope with the higher pressure.

no it has to work in line after the pressure reducer which you are required to use ( its the law)

Yes. You can set the pressure you want. When the line pressure drops a certain amount below that point, the pump comes on and brings the line pressure back up.

You can adjust the float action with the simple addition of a zip tie to lower the float level if it is not adjustable on yours. It also depends on if you are pumping uphill and how close you installed your back flow preventor

It does rely on water pressure for it's force. But I'm not sure how low is to low.

it is not under pressure. pond water is pumped into top where it soaks through the filter pads and them out at the bottom. There is an overflow spout at the top if too much water builds up, but can still leak if too much water. best to have a valve so you can better adjust the flow into filter

I've used it with some very low pressure before. It will work with any pressure really.

No. All you need is a pressure control valve or faucet valve that is designed to withstand the pressure if the water goes directly to it.

I have only used the mattress with this valve a couple of times, however, I have not had a problem. I always deflate the mattress so the valve is not under constant pressure. Hope this helps.

Have your boiler serviced asap. There is a problem if your relief valve is tripping at 30 lbs pressure

You will need a minimum of 15 psi and a maximum pressure of 100 psi. You can purchase an inexpensive pressure reducer that will prevent the pressure from exceeding 35psi and the valves will function fine at this pressure.

The pump is strong enough. A valve stem fitting does not come with the pump..I only use my pump for Halkey valves in pontoons on inflatables...

Yes. You will want to remove the pushrods before pressurizing the cylinder, so that the valves will be closed. I would also bring each cylinder to the top dead center position and lock the crankshaft so that it won't turn. This is extra insurance just in case you loose air pressure in the cylinder for some reason, the valve(s) won't fall into the cylinder.

Yes, but it seems quite serviceable. Admittedly, it might break before the rest of the valve, though

if you lose air, it won't be significant. Most valves are in-line, not 90 degrees.The shock, or wheel really should be designed for in-line attachments - not the pump's fault.

I don't think so, this is a static system, I would think that the additional pressure would cause leaks.

ask orbit my system is about 50 psi and i think it needs the source pressure to operate the valve

It does require some pressure... I would say a medium amount of pressure... More than I was expecting when I ordered it
