Mr. Strata live in a condominium complex in Highland, California. His home was over 40 years old and all of his toilets were 1.6 gal low flow toilets. He wanted to try to install in the master bathroom a duo toilet flush. 

This post shows the eight steps how to install the duo toilet system. This post is a review of this product. 

Step 1: Fig.1 above right shows that this is the toilet bowl before the Duo flush system was installed. Fig.2 below has the water flapper removed.

Step 2: Fig.3 shows the new Duo Toilet Repair Kit.

Step 7: Fig.10 Water tube goes directly to flush valve system. Now this system if fully functional. Mr. Strata had the system for three months before he decided to purchase new toilet from Sam's club. Did it work, Mr. Strata said it did but he wanted even more water flush than the system installed.

Step 8: Fig.11 shows the new system has been updated. The flush valve is very powerful. There are some warning that the system could overpower your toilet system. There are always warnings, if your concerned the best thing to do is to look it up on the Internet. You may have to go through 20 pages before the answer comes but it might be worth your time. What I do know is Mr. Strata is happy with the system that he received from Sam's club and so far there has been no complaints. But there is considerable differences the kit cost $30 the new toilet cost $200.
