Hymer water system problem

[Tigertom]

Hymer 2017 DL 588.
Getting ready for a trip after a few months inactivity and shower+ toilet flush ok but kitchen sink and bathroom sink taps have very low pressure.
Checked the pump, it has very good pressure.
Any ideas what might be happening?

One motor may have gone in the tandam pump, still works but lower pressure more noticeable on longer pipe runs.
Best thing I did on my van was get rid of the submersible pump and fit a Shureflo pressure switched pump.

The pump seems to have excellent pressure and the run distance to the shower is similar to the bathroom sink

Have your taps got aerators on them? Maybe worth a clean with white vinegar

The problems seems to have been debris and gunge collected in the taps filter/aerator.
Now sorted
