Guys, I have been kicking around this idea a while now and I finally went ahead and did it. I went down to the local pump supply house and bought a 2.1 gallon bladder tank. The unit is around 11"x 8" and fixes in next to where the electrical cord goes in. It took all of about 2 hours to install and does take out all of the pulsing and does have enough reserve to work the toilet at night without pump noise. The whole project cost aprox. $75.00 and i think weel worth it if I don't get woke up from a deep sleep. You may want to consider doing this.
