Yes it can. The pressure can get backed up into the vacuum areas of the motor and cause back pressure. The PVC valve will eventually get clogged so it it a good idea to change out the PVC valve at least once a year. It is a relatively cheap part and replacing it is definitely a DYI project. Should only take a few minutes.
Note* Be Careful with the Hose it is attached to. It may be old and could crack. If it does it can be replaced with automotive hosing that can be bought at any automotive store. Should be only a few bucks. If it is dried and cracked definitely replace it. Once again a DYI project that should take only a few minutes.
Hope this helps.
