Check Valves for Well Pumps: How Does it Work and Why they are Important 

glad you found our videos useful

I figured it out. It's on the input side of the pump.

absolutely it would

Yes, I recommend a check valve regardless of whether the temperature gets below freezing or not.

@@WendellLeeWellServices Appreciate the info thanks

sounds like a slow leak in your system

Found one small leak I also put a check valve on the water drum at the very bottom no I don’t lose prime thank you

That's 100% a lie you have to have a check valve on the end of a jet pump or you can't prime the line

yes, preferred pump or drillers service will take care of your needs. Thanks for watching

if the pressure wont hold when the pump is off. if the pressure starts falling as soon as the pump turns off, thats probably an indicator the check valve is bad and the water is running back in the well

@@WendellLeeWellServices okay, I am maintaining pressure. I think it's actually just the tank. 👍

@@WendellLeeWellServices Thank you for the video and the reply. Sorry for this long-winded response, but thank you if you can assist me and anyone else in a similar situation. Trying to diagnose if it's a faulty check valve at the submersible pump or crack in well pipe at pump or on the line coming into house without pulling pump since we're still in the negative temperatures here in interior Alaska and 100 miles from the nearest well drilling specialist. Cannot see if there's any water spots on ground outside from well casing to the house, since we're under several feet of snow and ice for a few more months (usually thaws in April/May, with water not fully soaking into ground/evaporating until June/July). I can visually see the water rushing back down the well pipe via the whole house water filter with clear canister installed just after the well pipe that leads into crawlspace from underground (pre-expansion tank). The canister will drain down to 25% water and fill up with air approximately 75%. This happens after the water pressure drops from 50 down to 30 psi when using water and the pressure switch kicks on at that time. Pressure tank is set at 28 psi. There's a second check valve right before the expansion tank/pressure switch, so harder to diagnose since the gauge doesn't lose pressure over time because that check valve prevents pressure drop and is working. After the pressure tank water is exhausted and pressure is down to 28 psi the faucets start sputtering with air and spurts of water, and then several seconds later the water will rush back into the filter canister from the well pipe along with a bunch of air bubbles. Once the water visually fills the filter canister again very rapidly, the water at faucets will continue sputtering before releasing brown sediment, and this takes approximately 20-30 seconds to clear up. Once the sputtering stops, a few more seconds pass before the sediment clears, and then the water is clear and the pressure tank starts building pressure again to 50 psi. This cycle repeats every time the pressure switch calls for water, and there has ALWAYS been water hammer once the pump cut off (the well pipe to crawl space will shake, and it has a foam "pool noodle" sleeve around it to deaden the noise). Been this way since we bought the home and didn't come up during inspection. Well and well pump installed 2019 when home built. Given the sediment that gets washed up every time, I was leaning towards a semi-educated guess/DIY diagnosis of a crack in the well pipe right above the pump, since that would create a water swirl that stirs up sediment that is getting sucked back into the pump and eventually the pump fills with enough water to overcome the air in the pipe and comes racing back up. After finding your video, now I'm wondering if it could be the check valve at the pump being bad. Again, sorry for the long drawn out reply/description. In your experience, has a bad check valve at the pump caused something similar? I.e. air in the well pipe, followed by sediment brown water before clearing again, only to repeat again, every time? Or do all signs point to a cracked pipe? Thanks again for reading. I know time is valuable.
