"Ordered this to replace a lower cost alternative to Saniplus macerator which has worked very reliably for 14 years taking the waste from a downstairs toilet/sink and also from an upstairs shower used daily. The saniplus finally failed a couple of days before xmas, and decided to replace. The XR was a cheaper alternative to the Plus, but offered very similar vertical/horizontal performance. It was a simple replacement and fitted the original pipework with almost no modification. The only difference is the XR is a little narrower so my side input needed extending (40mm pipe) which was simple to do. The XR is significantly quieter in operation and quicker to pump a toilet flush away. Time will tell on reliability, but will hopefully match its predecessor which was descaled just twice in 14 years, and just needed a replacement supressor fitting a few years ago (by an approved Saniflo engineer). The only downside to these is if used with a shower, they can get clogged if a lot of long hair is allowed down the shower drain. We now use a simple hair trap over the drain in the shower tray to try to avoid this. Otherwise recommended!"
