Frequently Asked Questions
Does This Kit Include Replacement Gaskets or O-Rings?
No; the kit does not include separate replacement components such as distinct replacement gaskets or o-rings. The reviewer notes included gasket materials are integral to the valve assembly rather than provided as standalone spare seals.

Is the Kit Compatible With Overseas Water Pressures?
