can i used without the sensor valve

you can but it takes forever to have the hot water. I haven't tried this pump without the sensor but I believe that the key to have instant water is the sensor. I like to know too.
1638585
Not a good idea but technically you can if you just want to shunt the hot/cold without it.
1638586
The pump will run all the time during the time you have it set to cut in. Not just when the water is cold.

Yes, you can. To use it without the valve, you must install a separate return line. This should TEE into your hot water line just below the shutoff valve under the sink, and run back to your pump, which is then connected (via a TEE) to your water heater's cold water inlet. If you have multiple sinks/showers, you'll need a return line for each one. This may be impractical or even impossible to do in some houses. If you are installing a new system, it's not difficult at all. Multiple returns can join together in a manifold, which is then connected to the pump. Probably the easiest way to set this up is with PEX piping. Yes, you can. To use it without the valve, you must install a separate return line.

No you cannot. With out the sensor valve there is no where for the pump to pump the water to. The valve gives the water somewhere to go, no valve = no water flow.

I don't think it will work without the sensor valve located at the farthest sink from your hot water tank.

Yes. As long as you have a return line running back to your water heater. You do not need a separate return line at every faucet. You need one return line. Follow your hot water pipe to the end (last branch takeoff), cut in a tee and run pex or copper. At the bottom of your tank style water heater there is a small, usually plastic valve. Remove that valve and screw in a 3/4" brass or stainless pipe nipple. Then install a tee inline with side outlet looking up and in the end of the tee put a brass drain valve to replace the crappy plastic one if applicable. The side connection on the tee you installed is where you will connect your return line you just ran. I did not notice if this pump had a built in check valve but if not you may want one to prevent water from flowing through both the hot water main and the hot water return to the faucet nearest the end. Water will follow the path of least resistance so the last branch on the main usually ends up being similar in distance to the water heater from either line. As a result water can back feed up the return line and will bring the cold water entering the tank with it. This is especially true when a second source of hot water is being used at the same time hence the need for a check valve.

No. I had to replace my sensor awhile back because I was getting hot water through the cold water tap. You need the sensor valve for it to work correctly.

Yes, the sensor can be removed and replaced. It may depend on the position it's in after it's screwed in.

There is no sensor, it is on until you turn it off. I usually let mine run al the time.

None what so ever.I stopped using it after 6 months as one sensor failed and too much hassle to get a replacement.

No nothing comes with the sensor. They were susposed to remove them from selling as they have issues. I returned mine as they didn't work at all.

J. Moore (thank you!) contacted the manufacturer and revealed its purpose in the Comments:"You might be interested to know that after contacting the manufacturer, I learned that this extra part is a spare mounting bracket in case you want to mount the sensor control lower onto the valve assembly. They sent me a variety of pictures (too voluminous for me to send to you here) describing exactly how one would make this attachment change. If you need to know more, you could call them at 1-800-488-6156 (7am-5pm MDT/Mon-Fri). They couldn't have been more helpful."

No. It's just the valve asm. A gauge may be bought separately. I transfered mine from my faulty valve.

I agree with Lawis' answer below. The old sensor can be removed from the fixture and replaced with this one.

You can use it, but you must have the air pump adapter on the valve to get a reading. http://www.amazon.com/gp/aw/d/B00DW444C6?cache=011ebe00f10d082a3a338bf9e69ad0e2π=SY200_QL40&qid;=1410197251&sr;=8-1#ref=mp_s_a_1_1

Just leave it alone. It's part of the sensing operation. Still think it is a great little pump!

No sensor included. If you do your own brakes, just monitor how much pad you have left and change it before the sensor gets tripped if you want to save a few extra bucks. MB sensors are not too expensive. BMW ones have a long wire attached and it runs like $30 to replace, ouch!

No, it's not necessary. You may want to consider using an exup eliminator however if you're planning on removing the exhaust butterfly valve altogether. Otherwise you'll receive a 'check engine' light. You can also just remove the exhaust valve cables without having to purchase the exup module.

I wouldn't unless you made some serious modifications to the unit. It is too unreliable. If you redesign the output valve you might be able to get away with it. I redesigned the one I have and it works very well now.

I bought only the sensor. I'm on my second sensor now I got about a years use out of the first one.

No it needs a connection to the sensor to work. The guage has wires for a 12v power supply, and also wires for the supplied sensor. So you need to install the sensor in your engine's water system and then hook that sensor up to the guage. Those wires are all included.

No. Not all are sensors. You may need one for some. It depends on what you are trying to do.

no, only one sensor comes in the box, to find the exact replacement for your vechile which, it is either threaded or flanged mounted, go to the denso web site
