- B8106 Pressure-Assisted Toilet Replacement Kit, Compatible with Select EcoFlush B8106and Flushmate 503 Configurations, 1.6 GPF / 6.0 L, Left-Side Control

Hi! I am not a plumber, but I learned a few things about installing this unit that I would pass along so that only one us us suffers the learning curve. This was a replacement in a Crane Bigfoot toilet. The combination works well together. So onto installation tips. (I kept having leaking issues, so I did this several times.) First, the handle control unit is extremely difficult to mount if you've already screwed the main unit to the tank. My suggestion is to line up the main unit with the tank opening, maybe even engaging a thread or two. But while the main unit is loose in the tank, put in the handle control unit and screw it down. Next, my leak issues. For all the world, it looked like this unit was leaking at the water input. But all of those fittings are pressure gasketed. (I had extra to deal with as I have a bidet seat. Highly recommended.) Yet there was water dripping down the lines, so what gives? It turns out that because this is a pressurized system, you have water leaking from the water feed to the bowl upon the flush! The first source was easy to find. I did not tighten down the tank mount bolts very much. When I took them off, they were little more than finger tight. No, tighten them with a wrench, but be gentle. The second leak was much more frustrating, but the answer is that you need to tighten the water intake port with a wrench as well. It also was finger tight, and common sense tells you that the hose connection is gasketed, and should not be leaking. ( I bought a new intake hose to prove it.) But apparently, this unit generates enough pressure that the bowl cannot accept all of the water at once, and so the excess goes into the bottom of the tank for a brief period, and then exits. Again, be gentle, but firmly wrench the nut on the intake, drawing the gasket into the hole. The unit now functions fine. I don't like tightening nuts on porcelain if I don't have to, but save yourself some grief here. Oh, and a plumber quoted me somewhere between $350 and $500 for this repair, so do it yourself!

Yes this part worked perfectly! Our toilet is working great! I would totally recommend this to anyone who has the same toilet. Installation was ok and it fit perfectly.

I bought this unit in February of 2025 to replace an older vessel. I initially installed without the proper gasket which led to a partially flooded bathroom. No worries, I just went to home depot to buy a universal-type gasket and that did the trick. The unit is working fine after several months and I will buy another to replace my second bathroom.

Had to use to replace an EcoFlush 8100 series dual flush model. Chose the 1.6 galon because it was the "higher amount" on the dual flush handle. Installed where the other one was. Tip - use a wooden clothes pin Half to help get the old handle off the valve witout scratching it. Used the 2 halves seperately as wedges to lift the handle off. It is just as much of a chore to install as the Dual Flush model. But it has been going for more than 3 years without issues. The dual flush model used to have issues with the valves at the handle asembly. This one does not.

Easy to install. Worked great.

This was bought to replace an old 8100 eco flush set, which stopped working after many years. This new set works well, and vet straight forward to install. The tricky part was to uninstall the old reset from the toilet water tank. Flushes very well! The Only thing is the pressure is very strong compared to the old model. Makes a huge noise when flushing that the other side of the house can hear clearly. My worry is if this will cause some leak in some time (hope not!).

Buenisimo

Works perfect!
