Hot Water Pump

Yep definitely. Is your plan to use the existing shower feed pipe and just boost the shower?

The existing feed pipes in the first picture will cover all taps and the mixer shower in bathrooms

Do you think I could use push fit 22mm or would the suction and pressure out be too much for push fittings?

Push fit will be fine, if properly fitted of course.

After all the pump comes with push fit hoses anyway

One of the benefits of doing it in copper is it will never move, it's important that there's a continuous rise back to the vent on the suction side

What you mean continuous rise?

So solder joints then?

You can do compression fittings if that's easier. If you look at your water takeoff pipework you'll see how it's angled up towards the vent pipe before it drops down, you don't want any point for air to get trapped. I'd still use the flexis supplied, personally I'd just do it in copper to meet the flexis above the pump if the existing pipework needs to move.

So the plan is cold cold/hot 22mm pipes below cylinder, 22mm 90 compression joints with pipe direct into pump then pipe out and 22mm 90 compression back onto cold/hot pipe to supply house.

And as the pump is sitting 3 feet below cylinder S flange not required.

This is a great help by the way
