20 Most Recent Shurflo On Demand Diaphragm Pump 28 Gpm 12 Volt 12in Model 12021000 Questions & Answers


When you turn on your hot water, the pump simply pumps cold water in to lower (cold) side of water heater which in turn forces hot out the top fitting to taps etc. My guess is if your experiencing poor or low pressure on hot water, it is most likely due to a faulty check valve that is located at the hot line fitting of the tank.

Take the aerator off the faucet and see if that makes it work better if yes clean the filter in the aerator on the kitchen faucet.

Make sure you have all the air out off the water lines that is about the only thing from your post that it could be.

Something inside is loose, like wiring or a part is lose in there and is shorting out on something or moving just enough for a contact point not to make contact, then when you smack it with your wrench you cause it move back to where it should be and it makes contact which allows it to run again. Take it to a small engine shop and have them repair it and let them know you have an idea what is wrong so they will charge you properly and not burn you, IF THEY HAPPEN TO BE THE KIND OF SHOP THAT WOULD DO THAT.

Sounds like a well pump with a leaky foot valve. I beleive you are correct in that it air lockes then when you shut it off the water flows back eliminiting the air lock.

you should check the foot valve that would be at the bottom of the well pipe the fasted way to check it is shut off the pump and see if the system pressure drops down

I could give more specific advice with a more accurate model number. shureflow's website does not have that exact model number. First, turn off power to the pump then try all the screws in the front for tightness. In general those type of diaphragm pumps have replacement parts that can be installed. I am assuming that the leak is from the pump not the fittings on the pump. if it is from the fittings reply and I will help you with that. here is a PDF of a SIMILAR pump. before you order make sure you have the exact match for your pump. most of the kits run about $15 Here is a good place to look for parts. make sure the material you get is approved for drinking water, or for whatever chemical you are using. There are several types of materials the pumps can be made from and you will need to pick the right one
Also consider the age of the pump it may be a better option to just purchase a new one may be the way to go, especially if you don't want to, or feel comfortable taking the pump apart to replace parts. There are also complete pump heads that can be purchased as a replacement. Hope this helps you out

Hello;
Water water everywhere.... The pump you installed has no way of knowing when to stop. Shurflo also has a pump with a pressure switch that senses pressure drop to turn on and back pressure to stop. I'm sure the dealer that sold you the one you now have will have the proper modell for your application.. Good luck and be sure to put a filter in the line coming from the fresh water tank. You should be all set with this recommendation._Ned_

The backwater valve or (check valve) is leaking back. Contact surflow and they will send you a new one for shipping only.

The market is full of brands making these faucets but how to decide which one is the best suited to your needs. Below mentioned are few things which should be kept in mind while making a purchase of a touchless kitchen faucets.

  • Position of the motion sensor
    It is important to check where the sensor is placed on your kitchen faucet. Their position varies from brand to brand. Some of them come with the sensor installed on their spout, while others have them at the bottom or the top of the faucet. It is up to you to select the one which suits your needs. Moen touchless faucets have two sensors, and the wave sensor is placed at the top which is responsible for the activation and deactivation of water flow and the other sensor, ready sensor is placed at the bottom, which is used merely for identifying the articles in your sink.
  • Power Source
    When it comes to a power source, there are two types of touchless kitchen faucets in the market. For the ones that need a continuous power supply you have to make sure that they are installed near a power outlet in your kitchen. The other type runs on a battery and can be placed anywhere. You can choose either depending upon your kitchen needs.
  • Others
    Before buying the faucet for your kitchen make sure its length, height, etc. is appropriate for your kitchen. Also make sure whether it is easily installable or not.
