Hey there… I’m shopping out a couple of your recommended pumps… the Power Defender 140 and 165. Currently I have a single speed 3/4HP pump and want to put in a variable speed. I have 1.5" piping everywhere. My TDH is 41ft. I am thinking that either of these would suit my needs (would they?) but I have a few questions:
-
I plan to self-install. Will the manufacturers warranty still apply? Part of my rationale for these pumps was to avoid Pentair (and presumably Hayward) since they apparently have become anti-DIY with their restrictive warranties.
-
The PD 165… does it support 1.5 and 2" plumbing?
-
Is there any benefit to buying the bigger pump? It seems like the smaller one would suffice flow-wise, but would it be worth the extra expense for the 165?
-
Are these quiet pumps?
Thanks!
