New kitchen faucet ''jerks''

When you turn on the water, it kicks/jerks/sputters about every 15 seconds. We've already ruled out air in the lines. Could a diverter do this? It has nothing to do with the sprayer.

    I have the same problem with a brand-new Price Pfister Classic Series faucet (double handle). We just installed yesterday. The sprayer is leaking around the handle constantly, and the spout "jerks" everytime you turn on the water and then about every 15 seconds. If you turn on the hot and cold at the same time, the frequency of the **** increases. If we remove the aerator, the jerking stops while the water is on, but still jerks when you first turn the water on. We are planning to remove the faucet believing it is defective, and take back to Lowe's for a replacement of the same faucet as I presume it is a faucet issue, since we never had a problem with our old faucet.

It's neither you nor an unusual problem. It's the faucet. We just installed a similar 2 handle $168 Pfister and had numerous similar and other problems. After 2 hours of expletive laden sweat, bruises, and continuous dumbfoundedness over the incredibly poor design of the cheap plastic pipe fittings and the poor english instructions, we turned it on and immediately had many problems.
1. It jerks the pipes every time you turn it on.
2. It sputters with irregular flow.
3. Pressure is 50% of our corroded 18 year old faucet.
4. When you turn it off, it drips for 10 seconds.
5. The flow out the spout is uneven and dribbles.

These problems are from its chinsy fittings and poor piping design.

1. The fittings are unstable plastic snaps held together only by pressure, O-rings, and cotter pins. No screw fittings at all. This is also dangerous since simply pulling the hoses and pipes such as when stuffing things under the sink could break the seals and cause a flood.

2. The flow diverter block that mixes the hot/cold and side feeds the separate sprayer is nothing more than a small block of plastic with very tiny holes infeeding the hot/cold lines and outfeeding the spout and sprayer. In other wrods, a 2 in, 2 out distributor.

3. The hoses that feed the hot/cold to the diverter take their feed from circular collar that seal the water with plastic-on-plastic pressure, held in place by more cotter pins. The holes in these collars that feed the hoses that lead to the diverter block in the center are also very small so they reduce pressure drastically and cause intermittent and sporatic flow.

4. Due to the very tiny holes in the diverter block, the feed collars, and the spray hose at the diverter block, any sediment or minerals in the water will soon render the faucet completely dysfunctional.

5. The design of the unit makes uninstalling very difficult. The sprayer feeder hose, for example, is made to push in without threads or pins so it has to be ripped out. The large thin ring washers with no gripping edges that hold the hot/cold faucet stems were very difficult to tighten and will be twice as hard to remove. The plain old wind nut style nylon washer-nuts used on l\more utilitarian econoical units are far superior. Shame on Pfister.

Answer: Due to all the above, the answer to your problem, unfortuntely, is the same as for us. To wit: There is no solution other than switching to another brand that doesn't place all its design effort in its looks at the expense of proper function. We feel ripped off. There is nothing uglier than a pig with lipstick.

Bottom line: These Pfister units are all show and no go. Return them if possible and choose another brand whose piping is hopefully more evolved and rugged rather than this plastic toy with only good looks.

    same problems with a price p. the diverter block holes on mine became jammed with a piece of calcium, causing the unit to leak. Cleaned it, reinstalled with no leaks....until i realized the cotter pin had worked itself lose on the cold side fitting. MAJOR WATER.

I do apartment make ready, I've to install countless faucets, bathroom and kitchen. Only recently have I had the same problem.

After installing your faucet and you turn the water back on under the sink, did you open the lines completely? In my case it was low flowing water.after completely opened up both lines, worked fine, the stuttering quit.

Start simple,

I just fixed my jerking/kicking/sputtering GROHE faucet by increasing the hot water line's pressure.

The installation video appropriate to my faucet helped me understand its inner workings, and enabled me to diagnose the problem and fix it:

If it's a single handle Delta faucet with sprayer, the diverter can cause this. It's unusual in a new fixture, but it's possible that some debris may have gotten into it during installation. Disassemble and check. Carefully flush the lines with the valve seats and springs and diverter removed.

Delta also makes parts for Peerless and some import brands.

No water to icemaker Kitchenaid french door KFIS25XVMS9

There is several reasons that could cause this. First if your ice maker has a switch turn it off for about 15 seconds then turn it back on then the push the ice control paddle in 3 times. This should start the "harvest", reach up under the ice maker it should start to fell warm to hot which is good. Soon the kick out fingers will start to rotate. If it all is working well it will kick out the ice, then fill with water. If this all works but no water, then it could be a bad water fill solenoid valve, kink in the water line, water filter, frozen supply line. Let me tell you this is at times will have you scratching your head, so have fun.

Price Pfister hot water runs slow

Check the supply line and valve to see if any dirt or foreign.matter got into the line or valve when you changed out your faucet. if this is not the problem you may have a faulty faucet. You may be able to back flush the faucet with a garden hose by leaving the hot side open, but you will get wet. If you used Teflon tape on the supply line and it is a compression fitting, some of the tape could be blocking the water. for more info go to

I have turned my shower on by the diverter then the water just stops. I release the diverter and the water comes out of the facet. Then I pull the diverter up the shower comes on and then a few seconds...

It is air in the line. I had the same problem. To solve it you need to find the main water valve in your house, usually in the basement, and shut it off. Then go to the faucet that is giving you the problem and turn on both hot and cold and let them run for a few minutes until there is no water coming out. Leave the faucets turned on and then go back to the main valve and turn it back on. You will hear sputtering noises as the water starts coming back through. Let it run for a few minutes. I had to do it a couple of times to get all of the air out. if that is not working, then you should try to do the same thing, but also open and drain the lowest faucet in your house, like in the basement. Hope that helps. It worked for me. <!-- from fixya rte -->

The temperature guage goes up and the car starts sputtering on a 1998 honda civic. Is it the water pump? the thermostat, the fan motor relay. The engine was just replaced as the timing belt went and this...

The normal rule of thumb is to start ruling out the little things before the big.

Process of elimination..


1. coolant level>leaks
2. quality of coolant.
3 check for blockages /air locks by squeezing hoses.
Take off your rad cap. Squeeze the coolant hoses. u should see the
effect of the squeezing in your rad level/resevour.
None of your hoses should be solid upon squezing them.
If they are , u have an air lock /blockage.
3 You can rule out the relay for the fan motor if it kicks in.
It should kick in around the 1/4 way mark on your gauge.
4.Check all fuses relaeted to water pump etc.
5.,Most commonly, it is the thermostat....for as little as they are worth, try one.
6. Listen under the hood when the engine is running, IF you hear a
whining, see if you can tell if it is coming from the water pump area.
If so, odds are your water pump bearing is shot.

Good luck.

Hi,i have a vaillant turbomax combi boiler,the radiator side is working well but when running hot tap the boiler kicks in for about 5 seconds ,hot water starts to flow then boiler cuts out,water runs cold...

Which turbomax, as there a two different models. The more modern one, with the brass CPL diverter valve, located at the front left of the boiler, was very prone sticking & jamming, this would restrict flow through the hot water circuit in the boiler, and cause cycling. Vaillant actually modified the diverter. You can identify, if it is the old type, as there is a very small hole in the middle of the diverter on the old ones, probable no more than 1mm-2mm wide. The modfied one, is much bigger approx 5mm wide. If old type, replace as this usally sorts the problem

This is an operator supported feature. You need to punch in this code.


destination is the number the calls get diverted to

nn = time in seconds (5/10/15/20/25/30)

This will work if you operator have not disabled this code.
