Results for "accumulator tank"

Noticed my RV water pump keeps pulsing and cycling on its own even when no faucets are running - is this dangerous with kids around? The water pump keeps turning on and off rapidly - like every few seconds - even when I don't have any faucets or anything running. It's doing this pulsing thing constantly.

I've heard someone mention something about an accumulator tank, but I'm not really sure what that is or how to check it. Could there be other things causing this too? I'd really appreciate some guidance on what might be wrong and where I should start looking. This is all pretty overwhelming as a beginner! …more

Got this annoying water pump vibration in my RV and can't afford a service call right now — any way to fix it for under $50? Right now I have 1/2" PEX connected directly to the pump discharge, but I've read that's not the best setup and can cause vibrations throughout the system.

I'm thinking about installing one of those braided stainless steel supply lines (like the ones used for household faucets) right after the pump to help dampen the vibrations. The thing is, most of the braided supply lines I'm seeing are 3/8" inside diameter, while my current PEX is 1/2".

I'm worried about creating a bottleneck that might hurt my water pressure or flow rate. Would switching from 1/2" PEX to a 3/8" braided line right at the pump discharge significantly impact my water flow? I don't want to solve the vibration problem but end up with weak water pressure throughout the RV. Any guidance would be really appreciated! …more

Every time I turn on a faucet in my new RV, this Shurflo 4008 water pump just won't quit running like it's stuck in overdrive! 🏃‍♂️ Even when I'm not using any water, this thing is chugging away like it's got somewhere important to be.

I'm pretty sure it's the high pressure microswitch acting up. As I learned, this can cause the pump to run continuously due to a high resistance short. The good news is you have multiple repair options:
- Replace just the microswitch
- Replace the pressure housing (3 screws)
- Or swap the entire pump (about $73 on Amazon)

Has anyone dealt with this before? I'd love to avoid replacing the entire pump if possible, but I'm also tired of listening to this mechanical marathon runner! …more
