Higher pressure with new heater

[mas985]

You really shouldn't wait so long to clean a filter. The manufacture recommendation of 8-10 PSI results in additional head loss of 23' of head which can severely restrict the flow of most any pump so I don't recommend doing that although it doesn't really hurt the pump. It is just really inefficient.

I would recommend cleaning the filter when the pressure rises 25% above the clean filter pressure. So if your normal pressure is now 21 PSI, clean the filter at 26 PSI.

As for changing out your plumbing, it probably isn't worth your effort.
