Hello
During kitchen rennovations we had a plumber remove our header tank in our attic.
Since then the hot water pressure is extremely poor (showers are a nightmare). Cold water flow is fine.
Any tips??
Many thanks

Yep. Ring the plumber and ask him.

Have had this happen to me before, the plumber probably didn't notice that the header tank is what creates the pressure. Basically Cold water is dumped in the header tank and the "head" is your working pressure. When is comes out of the header tank it acts as the water main to the Hot water cylinder and the pressure it creates with the "head" onto your Hot water cylinder is the pressure you will get in the shower. confusing??
To keep it simple... If he removed the header tank then he should of run the water feed directly to the HWC (not to header tank) to make up for the loss in pressure. He would then use a pressure reducing valve set to the old pressure and open vent to the appropriate height (or use a vacuum valve). The pressure would then be the same as before.
Maybe he did all this correctly and only has to increase the pressure on the valve?
Hope this helps

The plumber probably didn't realize that the header tank creates the pressure? Geez. Maybe the builder didn't realize that nails are meant to hold timber together as well!

Maybe the guy wasn't a plumber. You would check and make sure the pressure is ok before you leave the job aye :-X

To check if he WAS/IS a plumber you can visit www.pgdb.co.nz (http://www.pgdb.co.nz) - go to the public section and check the register - type in the person's last name and see if he has a licence.
