New fresh water pump installed

My new Shurflow water pump came in the mail yesterday evening so I spend the day installing it. It took almost all day simply because of how much hassle it is to get at. I had to remove my stored stuff from the bed area, remove the 4" memory foam mattress and move the original mattress to get at the pump. Then I had to go across town to get one fitting (1/2" barb to 1/2" MIP) for the strainer. I got some new clamps while I was at it. I only grabbed 3 when I should have gotten 4. I reused an old one that still works fine. It's just a bit rusty.

Then I had to refill the tank a couple times to cleanse the bleach water. I let it gravity drain out mostly instead of running the pump to empty the tank. Plus I checked for leaks several times before I put the bed and stuff back in.

All seems well... except for one slight problem. I had gotten a 0.5gpm aerator for my galley sink thinking it would be a good thing to have. I was wrong. At least with the setup as it is now. It causes the pump to cycle on and off constantly every other second due to the excessive back pressure caused by the water saving aerator.

If I remove it and run the facuet at a high enough rate, it doesn't do it. If I were to install an accumulator tank, it would prevent this. Much like the way the well was set up at the house I had. It prevented the well pump from kicking on and off or running constantly.

However, I don't hardly have room for an accumulator tank in the compartment with the pump. I suppose I could make one fit somehow though over the PEX fresh water line. I may go back and install one later if I find I'm consuming my water too quickly without my 0.5gpm aerator. I may also try a 1gpm to 1.5gpm aerator for now instead since it spits out about 3-4gpm as it is now with no aerator at all. I know it came with one but I can't seem to find it now. The pumps they make now are slightly adjustable. I tried adjusting it for my 0.5gpm aerator but no soap.

But aside from that issue, everything is dandy now. No leaks, the pump cuts on and off like it should when the flow is high enough out of the taps to prevent cycling.

I did go back and screw the pump down to the piece of wood after I took the photo, so it's not going to get jarred around or vibrate excessively.
