This pump mates to Signature toilet I also got from Amazon. Best invention since sliced bread when you need to pinch a loaf..haha! I installed it a year ago, and it gets regular daily use from a cottage 150 ft from septic tank. Pumps that long distance via a 1 in pvc horizontal run and no issues so far. Did not add extra check valve or anything and tried to make more round bends with 1/8 fittings instead of ells. It gurgles a bit for a minute after it shuts off as water siphons that long distance but not a problem. Not too loud either. Highly recommend!5/10/2022 The float valve was sticking and pump was running more than the usual 4 seconds. Simply disconnected the unit from the toilet after 1) shutting off water 2) flushing last time 3) bailing out some bowl water. It was fairly easy to pop the top off since there you just have to pry tangs slightly above catch on the ends. The gasket on top makes a pretty tight fit so you have to gently tug the top and valve assy comes out with it. See pictures. Note that a lot of grease and unmentionable does accumulate, and this is simply from the toilet in this picture and not a sink...product of high fat diet..haha Anyway there was no smell as it had been unused for a week and flushed a number of times, but still try not to spill. Then outside and a good going over with a toothbrush and garden house made it like new. Be sure to squirt forcefully up into the float assy so nothing jams the float later. Also removed the gasket and cleaned to assure good fit. You can see the pump sprays effluent all over the inside of the tank. Didn't see any rust, but I did not remove the float either to look up there so will check next time. Only chemical used in this toilet is Clorox toilet cleaner which is corrosive but no damage seen as everything seems to be stainless. Reassembled and workd like new. The outlet pipe which is only 1 inch on this one looked surprisingly clean although I did add a little low suds detergent ..very little..and poured a bucket of 185 degree water in after reassemble to degrease the line to septic. Been in full time use almost a year now and still looked like new...BUT obviously this unit is going to require annual maintenance. I hesitate to use any products to degrease the insdie, but it could be an option. If somebody wants to post a question about maintenance and then share a successsfully used product that would be great! Still highly recommend the unit....oh, and one last tip. When reconnecting the rubber sleeve between macerator and toilet be sure to thoroughly dry off the porcelain of the bowl outlet so that when you slip the sleeve on and start to work upward to pull it on completely the rubber sleeve will "grip" the dry porcelain and be your third hand. If it is wet you will spend an hour cussing and struggling to get it on there. And do not disconnect the sleeve from the macerator and take it off the toilet as I could only get it on macerator when it was out in the open. For what it is worth IMHO.10/22/2022 About 4 months after last removal and thorough cleaning the pump was again running long time due to stuck float valve. Mathew Rolls comment that he does the clean out quarterly sounds about right. I have been trying to soak it with hot water and use a biological enzyme to prevent accumulation along with soap etc but looks like there is no way to avoid the buildup and the needed maintenance unless maybe there is some powerful acid clog remover that would not harm the unit?? If there is such a thing will someone please post a question and then answer it on Amazon. Takes me about 1.5 hours to complete the job. And then a long hot shower...LOL. Jeff Goldblum's Jurassic Park question always remains: "You'll remember to wash your hands before you eat anything?" Haha Still love this pump..oh and PS REMEMBER that macerating blade is exposed on top when cleaning so WATCH IT! Or you'll be washing your hands in sewer water and bleeding all over the pretty white tank...like I just did! :)
