Have a manual for Jacuzzi Bath Perfecta EZ33 959 White round high-performance toilet?

SOURCE: How tight is the tank/bowl supposed to be a

They only need to be tight enough to sufficiently seal the donut between the tank and the bowl. Some movement is acceptable. It is better to be a little loose than to overtighten them and risk cracking the tank.

SOURCE: how to assemble tank to bowl

1. Place the Rubber Donut on th bottom side of the tank (this will form a seal from the tank to the bowl)
2. There are two small holes to either side this is for your two tank bolts. Place a washer on both bolts and place them in the two holes with the head of bolt and washer inside the tank. Place tank on bowl, matching up the holes.
3. there are two plastic nuts that are beveled on one end, with bevel up toward bolt head thread onto bolt finger tight. Repeat for remaining bolt.
4. Apply a little pressure to one side of tank and tighten nut finger tight again then repeat for other side. May need to do this a couple of times back and forth. IMPORTANT tight the nuts equally and carefull not to overtighten or you will crack the tank ONLY FINGER TIGHT.

The complication here is that Jacuzzi does not make toilets anymore than Sears makes refrigerators. In Sear's case their Kenmore refrigerators are from Whirlpool with the Kenmore name.

It is my understanding that Eljer was the manufacturer of the toilets with the Jacuzzi name typically sold at box stores. With that as a starting point, surf the web for any Eljer toilet tank replacement parts and see if you can find a similiar flusher

SOURCE: i need to replace the wax seal on my jacuzzi

I would just use the one from hardware store. nothing special about the wax from the manufacturer except the price...

be sure to do a thurough cleaning on the bottom of the toilet and make sure it is dry before you install new wax ring or it will leak.
you can actually use a hair dryer or set it in the sun to soften the wax ring, don't melt it, just soften it. makes a much easier time when setting the toilet down onto the wax.
