Hi all - hoping to get some beginner help. I have an RO System that has just started making a loud cyclical noise and leaking. I’m not too knowledgeable about this stuff, so hoping to get help from the photos (neighbor that shares the well took them as this is a weekend project property). I am not really sure what the grey box is - but since you plug it in, I assume it pulls the water from the pressure tank. The gauge on the right goes up and down with the noise. I will be at the house tomorrow, but wanted to see if there was any help/easy answers based on my description and photos. Or - if anyone has suggestions on what I can do to troubleshoot/photograph when I arrive [img]https://cimg2.ibsrv.net/gimg/www.doityourselft.com-vbulletin/2000x1504/26f8264d_eb72_4b72_a66d_f6cdd830b136_cba2fdd0ab88d54d0c25bbcb6a291a8a2659bd99.jpeg[/img] [i]Close up - TGI Topway Global Inc.

Hi, I have a well system with a big water tank and a jet pump at the tank to pump water to the house, with a sediment/carbon filter system inside the house. But I have a problem with scale build up in the pump and check valves at the tank, and in the pipes from there to the house. This destroyed my old pump earlier this year when the non-return valve between the tank and pump seized open due to the scale, and I didn't notice until it was too late. I now have a new pump and have replaced the two brass check valves with stainless steel ones, since those should be easier to descale, and put in screw couplers so that I can now pull them out easily to descale them. But that doesn't help with the scale build up in the pump/pipes. What I'm thinking of doing is to put a polyphosphate filter (like the Express Water WH100SP) in the tank outlet pipe, before the check valve and pump. Does that sound a solution that would work? Thanks.
