Hi All,

I'm new here. Hope you folks can help.

I have finally tired of my wife complaining about waiting for hot water at the shower. I am looking at the Grundfos Recirc pump. I have a question:

Since I have two water heaters running parallel will I need to install two pumps or just one pump where the two hot water out lines connect? I'm thinking one will work but I thought I would ask.

Thanks!

First, in order for the circulating pump to work you need a return line so the water can circulate. Do you have a basement and is it finished.

pump install

if you have two water heaters in parrell,
you are going to have to install the return line
into the cold inlet to the water heaters BEFORE it
divides off to both units, and you will have to install
a spring loaded check valve before this connection
to keep the water from going back up the cold line..


ps......you are opening a huge can of worms here because

all you are realy doing is spoiling your wife, once she realizes
that you are willing to go through all this trouble to please her
it will never end...

A wise man.
Your name should be "master AND plumber mark".

zma98,
All you're doing is reinforcing the idea that her nagging gets her what she wants. Like giving in to those screaming kids in the grocery checkout line. If the dog takes a leak on the carpet, do you give it a bone?
You can lead a horse to water, but cannot make it drink.
But if it does, it'll expect you to lead it everywhere anytime it wants anything!
Now, that said, do you want a project? If so, go ahead. Plumbing and building stuff is fun.
Like my buddy Sean said to his daughter when she asked why we were working on our project in the garage. "Honey, a project is something Daddies do when they want to get away from the Mommies."

Mark, I like it, you can boil it down to this:

One thing man never learns from history is,

that man never learns from history.

Sorry about the smart a** comments.
I thought that you should put the water heaters in parallel. That way you are assured that one is not doing most of the work because of uneven flow.

This is awkward, but...
