Does anybody know whether the inlet ball valve and the sieve (under the high booster pump) are located in the valve cartridge?

Two parts. The housing contains the cartridge valve and a separate "frit".

When removing the valve cartridge from the housing, (at the base of the booster pump) is the 'frit' visible to replace??
Thanks Aman

As stated, the housing contains the valve cartridge AND frit. Stand back and look at the high pressure pump. Notice how one of the two valve housings on the bottom appears to be longer than the other. That is the one with the frit inside. After removal, look inside the housing and you will see the frit.
