Hey fellas. Dealing with another issue here in our house. We have two sump pumps in the basement, one in the front and one in the back. The one in the back is used continuously since that's what the sink and washer dump into for drainage. All of the plumbing is 1 1/2 inch. The sump pump pipe comes directly up to the ceiling of the basement, 90's off to the left and then Y's into the main drainage pipe. This pipe has a slight angle on it so water trickles to the left. About 5 feet to the left is the drain to the bath tub, which has a 45 up, 45 to make it horizontal again, followed by the trap and ultimately the drain. About 3 feet beyond the bath tub is the main outbound pipe where the toilets are hooked into for drainage, etc.
When the sump pump runs, it must be pushing a lot of pressure through that pipe. I hear the kitchen sink gurgling (which is on the right) as well as the bath tub gurgling and ultimately you see water in the bottom of the tub. I have some mixed thoughts as I'm not entirely sure what is optimal versus what is practical.
Option 1 - Install a dedicated line for the sump pump and Y it into the main line right at the main junction exiting the house. This is all well and good, but at this point the PVC is transitioning over to galvanized and it's smack dab against the wall. Plus, in order for me to Y it in PAST the tub, it's going to require a huge magnitude of work because there are several other junctions coming in at this point, all galvanized. Plus this area goes through a wall, making things a bit more difficult.
Option 2 - This was my initial thought. I began to wonder if I could make some sort of tub in between the 2x10 joists of the ceiling to hold the water. Then from there, based on gravity, it spills into the 1 1/2 inch outbound pipe and flows out accordingly. By doing this, I leave all current plumbing intact. The goal here is the sump pump would disperse all of the water in the pit to the chamber in between the joists. That way, due to the extra room it would gain from the suspended tank, it wouldn't be as pressurized to push through the drain pipe. Then, as I said, gravity takes over and it spills into the pipe exiting the house.
Option 3 - Check valves. I've never used a check valve, but I was asked why I wouldn't consider one. The kitchen sink isn't the issue, it just gurgles (despite the annoyance), but I wonder if I could put a check valve in the bath tub pipe to keep the water from coming up? Is that how check valves work, or am I anticipating using them in this instance in a completely incorrect manner?
Overall, I know option 1 would probably be the one that makes the most sense. Option 1 will however guarantee a huge magnitude of work along the way, which is what makes option 2 (or option 3 if it's applicable) slightly more attractive. That being said, here I am asking the experts. Thanks for your input fellas! :thumbsup:
