A while back when we had the water in the basement one of the problems I saw was that the AC was trying to drain the condensation into a hole cut in the basement floor with some pea gravel in it. Once the ground was saturated the water would come out and spill onto the floor. Add in that Maisy from time to time thinks that she would love to crap in a 3″ diameter hole of gravel instead of one of the three litter boxes we have set out, and I figured it was time to close down the hole in the basement floor.
So I bought a condensation pump. I had a temporary setup where I snaked a 30 foot 1/2″ hose across the basement floor to the drain that goes to the septic tanks, and the PVC just angled into the pump. It worked to get us through until I got time to get it in properly. That was today.
I put together a list of materials I would need and set off for the hardware store. I got my two 90 PVC elbows, a joiner, electric box wire clamp, 4 foot of 18 gauge wire and 50 foot of hose. First thing was to shut off the power to the furnace so I wouldn’t shock myself getting the pump wired in. Then I took the 18 gauge wire and connected it to a safety switch on the pump in line from the thermostat and the blower control panel. What this does is if the water in the pump basin goes 1/2″ above the float, the safety switch interrupts the thermostat to make it turn off the AC/furnace so no more condensation can be produced until I get the pump fixed or replaced. This should prevent any overflows and water in the future.
Next I popped a plug out of the single gang electrical box and put the wire clamp in place. I cut the two prong plug off the end of the pump cord and fed the wire into the box. The hot was already split to I simply took the hot lead from the pump and added it to the wire nut. The neutral on the furnace was an unbroken strand so I had to cut this wire and then tie my pump lead into that. Turned the breaker back on and a quick test to make sure the blower and thermostat still worked as I expected and then I was ready for the PVC.
This wasn’t too difficult. I just had to get the path I wanted from the back of the AC unit over to where the drain basin to the pump. Got it all glued in place and made sure I have a slight down grade on the run so the water flows slowly out of the PVC and doesn’t spill over the drain basin. I left one down junction unglued. In the past I have found this useful when the inevitable plug happens and I get to suck stagnate condensation water out of the drain pans. Worst taste ever.
Next I had to get my hose run from the pump over to the floor drain. This means a 7 foot straight up run to the bottom of the floor joist then over and back down to the floor drain. Just above the floor drain is an old laundry tub. At some point in the life of this house someone had the idea that they needed a water lead from a pipe that went to the laundry tub and used one of those stupid water taps that punctures the copper pipe and has a twist open valve that feeds the small supply line that comes out of it. I really don’t like these things as I have always seen putting a hole in the side of a pipe as a stupid thing to do. Today is the reason why it is stupid to use these tap valves. I hit it with my little 1/2″ rubber hose and it sprung a leak. Great!
So since this house is old and they apparently never thought a shut off valve to anything was a good idea, I had to shut off the pump and start draining every drop of water from the system, hot and cold water. As it was draining I drove down to the hardware store to buy two 1/2″ copper caps. We have been saying that when we remodel the basement, this laundry tub goes away. So instead of fixing the pipe, I am just going to cap it and be done with water to this tub, I will remove the tub when we get to the remodel of the basement level. Got the pipes capped, while they don’t look great, it works. Turn the pump back on and get the system pressurized again and refill the hot water tank. I am re-plumbing this house once we get everything torn out of the walkout level. It is all going to be pex and a shut off valve for every run.
Finally I get the hose mounted in place and do a test run of the pump. It works great! This project took me about 5 hours start to finish which is way longer than I it was going to take and don’t know what took all the time. Even though I had to do some plumbing I wasn’t planning on, it really didn’t seem like that long of a detour. Oh well it is done, looks good, functions better and now we shouldn’t have to worry about condensation ever dumping on the floor again.
