This kind of pump uses an impeller (like a fan). If you test the suction when it is running dry (that is, you are just pumping air) then the amount of suction that an impeller can create is pretty small. However, if the pump is pumping water, and you put your finger over the inlet hose (while it's under water) you should feel a great deal of suction. If the problem is that you have clog on the output side of the pump, you will still feel plenty of suction when pumping water. However, if there is a problem with the impeller (like maybe the blades are broken off or worn down) then you won't feel much suction, even under water. I hope you find this helpful. Al Kupchella

I take it that you are talking clutch system . There will be little pressure in the master cyl side until you bleed out all the air. The suction you feel is when the piston returns and draws in more fluid from the reservoir so that there is a full charge of fluid for the next stroke. remove the bleed screw and place your finger over the hole and use your finger as a valve until you get full fluid flow. Replace the bleed screw and finally bleed out the air . that got in while you were replacing the screw.

Pump won't prime any higher than basket. It has a good water flow into it. Just put in new seals on cartridge lid and basket cover.Don't see any cracks anywhere. Used lube on seals. Has been an off...

The pump is sucking air from somewhere. First, check pool water level and make sure it is up a few inches in the skimmer. Then, make sure the gasket on the square lid is in proper place and lubed. Next, check the drain plug on the bottom of pump housing in front of suction side of pump, and make sure there is a rubber gasket on it and tighten, if no gasket, remove and put 8-9 wraps of teflon tape on it and put back in and tighten. next, check the pipe going in to the pump and try and turn it or move it clockwise or counterclockwise, if it moves even a litttle bitfreely or has slop in it, it may be melted from pump running dry at one time or another. to repair you will need to cut the pipe on the suction side, 2 inches past the back of the fitting that screws into pump. unscrew loose fitting, wrap with 8-10 wraps of teflon tape and re insert and tighten. install a coupling on the remaining open ends. and last but not least, if all this above didnt do the trick, you will have to have your suction line pressure tested for a leak.

Where do you put refrigerant for the air conditioner?

If you are using an adapter to connect between a can or refrigerant to the suction side of the AC then make sure the screw is fully backed out and screw the can into the adapter. Start the engine and turn on the AC. Remove the cap from the suction side refrigerant port. Screw the hose fitting onto the port. Screw the peircing pin into the top of the can and you should feel the can start to get cooler. Let the refrigerant evaporate in the can but don't turn it upside down. Shake it to determine if it is empty or not. When it can be easily warmed with you hand and feels light in weight the refrigerant is completely in the system. Remove the fitting from the refrigerant port and replace the cap. I hope this helps.

Hello, I have a pentair whisperflo 1hp pump and it seem to have very little water pressure coming into the basket and my skimmer has very little suction as well. Any suggestions Thank you, Ali

turn the pump off, remove the lid and pump basket. reach your finger inside to see if there is any debris caught in the impeller. MAKE SURE the pump cannot come on at any point while you're working on it.
That should do the trick, if not, investigate an air leak on the suction side of the pump. Causes: bad lid 0-ring, threads on suction fitting leaking air in, or if there is a union on the suction side, make sure it's tight and the o-ring is in good condition (add lube as necessary).

Im new to this pool thing just got a house we a yr old hayward pro seriess210sv, an have no suction or water running in valve clear cover, what do i have to do please help

Remove the cover, put water into the basket, keep filling it even after it spills out onto the floor ... well just for a minute or two. Close the top and snug the hand screws. Make sure the water level is high enough to pump (I. E. water in the skimmers) turn on the pump. Wait up to five minutes to get suction. If nothing is happening ... I would suspect that you are having impeller trouble. You don't say what kind of pump you have ... it must come apart ... be prepared to replace the impeller and all seals that you encounter. If there is a ceramic face seal involved, try to not touch that surface with your fingers.

Let me know what happens.

Good luck in your repair.

Need instruction and advice on how to hard plumb my above ground pool.

You have to find out what are your suction ports (for example skimmer would be one you probably don't have a main drain)once you have all suction ports located pipe separately back to pump and create a manifold so that you can isolate each suction port with a valve on each line then tie all back into a single line then into suction side of pump then pipe return side of pump back to the return ports of pool installing a valve as you come out of pump you don't have to separate these lines.

Suction cup on tom tom does not work any sugesstions?

Use a computer or TV screen cleaning solution on the windshield and the cup then lick your finger and wet the cup. Also check for a lever that adds to the suction, if this lever is on your device and is in the wrong position, it will not stick. Also you should affix the unit to the window when the temps are at a median point, if you put it on when the car is 100 degrees it will fall off in colder weather, and vise versa for 0 degrees.

Hope this helps.

Removing fan to replace water pump on 1994 318is bmw

Not sure if it is the same, but I have a 1996 328i and the fan is attached to the front of the water pump via a large nut. That nut is a 32 mm (1 and 1/4 inch fits it as well), and is BACKWARDS threaded (i.e right to loosen and left to tighten). You may need to use a pair of vise grips and lock onto the belt to keep the entire front of the motor from turning. I have also heard giving it a few good whacks from a rubber mallet tends to get them to break free. If you do have to use the Visa grips on the belt be careful to not break your water pump pulley. Although it looks to be made of metal it is actually made of plastic and will break if it gets caught up in the tension of turning that fan nut. When the motor is running it is turning in the tightening direction, so I put some anti-sieze on the threads before re-installing. Hope that helps.
