How much pressure should be coming out of the Danner AP 20 pump? Can block it with my thumb. Changed parts.

I couldn't tell you exactly, but know I get quite a bit of pressure from mine - I had to swap it with the one I was running on my outdoor pond. I was using the Danner for my six indoor aquariums - ranging from 10 to 100 gallons and was losing water because the air pressure was so high - afraid if I tamped it down it might cause the apparatus to break down prematurely. So I had a fairly powerful - but adjustable - pump to aerate our pond, I swapped them out. Have perfect aeration from one central pump inside and have run six air hoses to the pond with plenty of force. I imagine you might be able to block it with your thumb - but it would meet a lot of resistance.

I don't have an answer for you on that one. I didn't try what you did. The pump worked fine, we are using it as a spare.

I can block it with my thumb too. Not sure how to answer this question. All I can tell you is that this is the best pump I have ever bought for my koi. They love it and the pump lasted outside (covered of course from sun and rain) about 7 years. My fish fricking love it! When I turn it off to clean the filter they all go down to the bottom and just lay there. But as soon as I turn it back on, it's like club koi again. They dive all through it and let it lift them to the surface (so cute). And these are like 15lb koi. And it's been nice for this artic freeze b/c it keeps the water from freezing.

That's a long haul... Hope the point is not too deep.... Anyway the pump inlet is 1 1/4 so you'll want to adapt down from 1.5 pipe to 1.25 right near the pump

At the tip there is an Allen key slot that loosens the metal tip (siding or sheeting), for siding I had to modify the tip to give a deeper offset and I run it at 80-90 psi.

Let me check with my husband. I think his biggest problem that I have heard him comment on is trying to get the pressure just right for the gun. I know he does like the gravity feed much more than the siphon but has used both. I will ask him tonight and email shortly. Overall he is really happy with it.

That is pretty low for a high pressure cutoff. Numerous youtube videos describe how to adjust pressures on these. Turning the nut with the small spring counterclockwise should reduce high pressure cutoff, but you'll need to also adust the nut with the large spring to change the range so that the unit will still turn on at a lower cut in pressure. Probably someone will have a more definitive answer.

More info needed. It could be hose thread or M22 and anything in between. What is the application? What are you connecting to and is it under pressure?

I have seen as much as 50 psi give or take how quick you are removing it. I'm a heavier rider so I have to wrestle with it a bit but it doesn't usually take too much longer to get correct. I'd suggest a decent pressure gauge to ease the issues. Good idea to have one of those anyway.

Works great. Let me know which engine your running and I will tell you which pressure regulator to install ahead of it. You need a large micron pre filter ( 30 micron is great) and a 10 to 20 micron between pump and rail. Keep the inlet side 3/8 to keep from restricting pump. That's the mistake people make and burn the pump up from starvation. Good luck with your project .

The pump works very well. I have seen pressure as high as 85 psi. This is not recommended as it could cause pipes to burst. Set presser switch to 60 cut off, 40 to cut on.

hi , use both hands one at 2 o clock and one at 8 o clock position at the same time yank it out ! if it is installed for a long time you may need to use some kind of spray lubricant like WD-40 around the edge but it is best not to use any thing so when you installed it back it will not pop out if you drive over a pump good luck :)

Sorry, I don't have anything that I pump to that pressure. I go to 65 psi on the tires on my Jeep Wrangler sometimes and I don't notice a problem with it doing that job. Guess I could try pumping into my portable air tank, I always called them pig tanks, it is rated to 125 psi. Hadn't thought of trying that so thanks for triggering the idea. Will give it a whirl.

No. Your problem is that you have too much back-pressure, which in other words mean that the hose you are using is too small. There are two options here- 1. You can make a hole in the hose right where the hose connects to the power head. That would alleviate the back- pressure on the pump. (keep in mind that you will have water coming out of two different places on the hose, the tip of the hose and from the hole you made). 2. You can eliminate the hose- you don't have to use a hose, you can use the power head by itself.

What is really important is your psi Pressure machine. if yours is a gas pressure machine I do not recommend to use this, even if this one gun is a very high pressure. 1700psi.If your machine is over this limit or very close, it is better you do not use it. It could be damaged o broken

if this is like the 1 liter one I have, there should be a little insignia of an oil can right in front of the trigger on the top right before the brass rod that goes down into the cup. From what I have gathered, it is not oil that is needed but every now and then add a little petroleum jelly or other water NON-soluable grease just to keep the o-ring pliable...if it dries out, pump won't work...go to Solo site, this explanation should be there

A) Does your unit push air out when not connected to anything? If so, it sounds like a problem with your hose or something else on the unit. If not it has to be after the pump. Either the tire or the connection are at fault. B) Try pushing the metal pin in the valve stem to release pressure. If nothing happens you are either out of air or it's broken. It should flow air with little to no movement. C) If that worked it has to be the connection. Maybe they don't align anymore and can be bent, or maybe you have to buy a better adapter. I'd get something like this(http://amzn.com/B001CJHU9W).

34 psi on your filter pressure gauge sounds way too high. Esp. since you say it was 10-12 last season, which sounds like a normal reading. I'd say your problem is that your filter is very very dirty, or you have something blocking the pipes (or both). I used to have to push a hose into the skimmer intake, forcing water to the pump, to clear the pipe.

Point the pump at the glass, not down and that should help. .. I have 2 on my 29 biocube and have no issues.. A 240 is not enough in a 20 gallon if used alone so I would at least pick up another 240 for the opposite side .. Do you have enough rock or is the flow getting obstructed down ? Mine are placed mid level in tank and again are pointed at side glass
