is there a pressure control valve. Is there some sort of heat protection for the pump

You can adjust the output pressure. You can download the manual from generac and see more answers you didn't know to ask.

Yes it has pressure control valve and the pump has relief value to release the hot water .

Yes, the pressure control valve is not optional. The heat protection for the pump is the water running thru it. It does get hot. I've used it for about 100 hours now and am very pleased.Manual: "If you run the engine on you power washer for 3-5 minutes without pressing the trigger on the spray gun, circulating water in the pump can reach temperatures above 125F. the system engages to cool the pump by discharging the warm water onto the ground." -- I would not let this happen. I don't know about the relief valve. (yes, it is there. Just did not look for it.

There is no auto pressure release valve to my knowledge.. I know this because if it doesnt start after the second or third pull you MUST release the pressure in the line ( trigger to release pressure or pump lock-up). Having said this the unit does have a variable pressure valve -100 PSI up to 3100 PSI- which I always turn down the pressure before shutting down ( aids with re-start). I do not believe the unit has a pump over heat protection circuit.. I shut the unit down if I am going to have it sit more than a two minutes ( engine running) without pump pressure release. Quite honestly I purchased this unit for the variable pressure feature.. I am quite satisfied with this unit... though other Generac equipment I own (generator) has been very problematic.... cheap Chinese engine and carb... Generac would be wise to use solid name brand engines like Honda, B&S, Yamaha.

There shouldn't be any protective plugs. As long as you have a good connection on the valve with your pump, air should be going into the tube. Often the pump will have a small lever on the connector. Make sure that is open when you attach the connector, then close it on top.

Yes it has a built in pressure switch, installed it in my Rv a few monthes ago works great.

The pump I received had hose for intake and out put and new shutoff valves. I am very pleased with the purchase. Good Luck

I'm not sure for thermal protection but it does have a automatic shutoff for tank pressure. Once it reaches a certain pressure it will shutoff and then it will turn on again when the pressure drops below the threshold.

can you give it one more pump to take off the pressure and then push the safety lock off???

Yes, because the pump is controlled by an integrated automatic pressure switch which turns the pump off when the line pressure on the downstream side of the pump reaches 45 psi, which should be a safe pressure for your water heater. This would not exceed the normal incoming pressure found on most municipal and rural water systems, which have no automatic shut-off capabilities. However, it is dangerous to use a water heater without a pressure relief valve because in the event the heating source fails to shut off when the water in the tank reaches the desired temperature, it can begin to boil and form steam pressure, which would be very dangerous in a house water system.

- No check valve included (cannot recommend one as I just installed the pump into the existing circuit)- I don't think this is the correct pump for an irrigation system- We use if for our house water and it definitely needs to be used with a pressure tank

Yes, it has a pressure valve. It cools down like all other pressure cookers and it cooks super fast. On some things you can cool it down by running water over it. The booklet that comes with the cooker is very helpful. I love this cooker!

In addition to the other comments you have the option I to put in a pressure reducing valve. Be cautious that you do not restrict pump flow too much as it may overheat, but I have never even gotten one warm. You can split the outflow to return volume to the inflow (a circle) which reduces pressure. By putting a valve on the rerouted flow you can control how much gets diverted and how much pressure gets reduced.

well, there is a valve if you would like to release the pressure quicker, that is not automatic, you have do that manual, its not hard, but you do have to careful when you do release that valve. So, far pretty satisfied with the product.

Yes this pump has a pressure switch and will begin pumping when faucet is turned on and then stops when turned off.

I agree with Marlowe. The pump can't be regulated, however I put an inline regulator in my system. Pretty simple fix to regulate max pressure.

The one I bought did include a pressure gauge, but that has been a while back and I don't have the provider information. Most of the suppliers will have the entire package content displayed, or they can be contacted directly.

No. It is only a simple check valve for a water hose type system. If you want to reduce the water pressure, then you would need to insert a restrictive rubber washer or else get a pressure regulator.

I just screwed it right below pressure guage with some Teflon tape. Great pump. Hope this helps

This would not be a problem for the pump, but you would need a controller panel for it where you could schedule any change in speed and simultaneously control any valves that might need to be opened or closed. I would call their technical customer service. My phone call to them after a long wait was more helpful than I anticipated.
