Hello all, I experienced some issues today where all my toilets trap water are ejected outside of the toilet. The issue I found is that the "sewage" sump pump might not work correctly instead it pumps air into the venting system through the vent pipe and cause all toilet trap water spilled outside. [b]Question 1[/b]> This is sewage pit but we don't have a basement toilet system instead it just has some clean underground water and condensation water from furnace. Do I still need a vent pipe? If I can remove the vent pipe connected to the pit, I can prevent the issue happening again where it pumps air into the venting system. As I said, we have this setup for more than five years and never had such an issue. The new zoeller M267 was installed a few month ago and works perfectly until now. The replaced system was a Zoeller M98 without check-valve. [b]Question 2[/b]> Does my sump pump installation have any issues? We have the new pump & check-valve for more than three months and never had such a problem before. As shown in the picture, the pump has a quiet check-valve installation near the base and there is also a drilled vent hole to prevent air-lock. Thank you [img]https://cimg1.ibsrv.net/gimg/www.doityourselft.com-vbulletin/750x1000/img_20220114_132818_f7e4b1904170cc8cb00e268a4702b6558948a0d0.jpg[/img]

My water pressure has slowly been getting worse over the last year and its at every faucet. I have a shallow well with a 1/2hp flotec jet pump thats about 4-5 years old. Its noticably louder and when the water is in use it drops to 30psi and will stay there instead of climbing back up til you turn the water off. Should I take the pump apart and see if its blocked up with sediment or just replace it? What other causes could it be? Foot valve? One way valve? If I replace it will an iron pump be louder? I was looking at this one thats very inexpensive and more powerful: [url]https://www.homedepot.com/p/Acquaer-3-4-HP-Dual-Voltage-Cast-Iron-Shallow-Well-Jet-Pump-SJC075/302910770#overlay[/url]
