I had been expecting someone else to answer this.

Latin aqua and Latin equus are not connected.
aqua < *akW- (probably h2ekW-)
equus < *ek'w- (probably h1ek'w-)
Note that they have different laryngeals, and one has a single consonant,
while the other has a consonant cluster.

Sanskrit apas is a different root again , *ap- (presumably *h2ep-)
