That's hotter than I would have expected. Thank you for several good points.

Interesting consideration; thank you. I had the impression that if poly pipe heats up enough to drop the pump, it softens enough to let the barbs slip.. I wonder whether there would be enough heat to soften a polypropylene rope enough that the pump would tear through the knot. Polypropylene...

The use of a safety rope in a water well seems to be highly controversial. Some pump manufacturers and well drillers recommend one, while other experts such as Valveman here argue that they aren't needed and can fall into the casing, forming a wedge that prevents removal of the pump. Leaving...

Thank you, Bannerman. The close-up photo is of the hole in the well cap that's filled by the square-headed plug in the other photo. The diameter of the hole is probably 3/4". The well is in a small well house; freezing isn't a concern in this climate.

Thank you, Reach4. The hole was difficult to photograph, but you may be able to see that the light blue tube starts just below the threads, and the smaller diameter tube starts less than 1/2" below that.

This well was drilled in 1978, apparently before putting a vent that rises from the well cap was common practice. The hole in the photo is filled by a simple plug, which I removed so that I could pour a diluted bleach solution into the well to rid it of coliform bacteria. I know the procedure...

Thank you, Cary. I don't see any sign that it's still pumping sediment. The sediment in the tank may have accumulated from the well being used only once every several months and very briefly each time over several years.

Thank you, Reach4. My alternative method seems to have worked, as I'm not getting any more sediment out, even when I let the tank empty completely on full blast.

Thank you, Fitter30. It's definitely silt; it looks exactly the same as the subsoil around here. Filling from the bottom drain isn't feasible without removing the tank from the well house. Would my alternative work, however slowly?

Thank you, Reach4. The drain valve would probably release more sediment, as it's at the center of the bottom of the tank, but it's also inaccessible there without disconnecting the tank from the well. What you suggest re 10-20 seconds is essentially what I did 15 times, and it removed a lot...

Does the following idea for clearing a pressure tank of sediment make sense? I have a 6" well 200' deep that has barely been used for the last several years, as there was no house on the property. I've built a house there, and the well will supply my water. Lots of brown sediment comes...

Thank you.

Thank you. I hadn't thought of that, as nothing will be higher than the filter, but it seems worthwhile in case there's enough water in positions where it might want to drain back.

Thank you. The instructions from the retailer call for shutoffs on each side, but I'm questioning whether they're needed, as the shutoff for whole house will be a few feet away. Can you think of any reason I would need the shutoffs? If I need to bypass this filter, I can use a nipple to...

It would be great if Jimbo or Redwood sees this discussion and weighs in. Something on the order of 10% of the reviews for this type of housing complain of leaks, mostly at the O-ring or the pressure relief button, but a good number say the housing cracked open. I wonder whether some of that...

Just a very quick sampling: in the following discussion on this forum, a plumber and a master plumber both advise against male metal into female plastic, the latter saying, "Avoid screwing metal male threads into a plastic female whenever possible."...

Thank you for taking the time to find those links, Reach4. I've found lots of apparently approved PVC and poly nipples there and elsewhere that are inexpensive till you add the shipping. I'm just trying to learn whether there's something about them that prevents Home Depot and Lowe's, who sell...

Thank you. I'm looking for 1". I will have the filter sit on its bottom, not be held up by its connections. Do you still suggest stainless, and if so, is that because stainless would be cut, not cast?

Thank you for your reply and link, Reach4. Sources like https://www.irrigationtutorials.com/faq/connections.htm offer good explanations of why metal shouldn't be threaded into plastic, which is probably the warning you were referring to. You make a good point, though, about the plastic on the...

The very common Pentek Big Blue water filter housings have 1" FPT inlets and outlets made of polypropylene, as do many similar filter housings. Many much taller filters and water conditioners have MNPT inlets and outlets that seem easiest to connect using flexible steel connectors with FIP...
