If this isn't the correct forum them I apologize in advance. I'm no plumber but about 12 years ago when I was renovating my first house I learned of this website and the advice I received back then was great! I have a new situation at a new house and would love any input anyone would like to offer. I've read about Cycle Stop Valves but most of what I read is in reference to well water. Here is my situation.
My home is on city water with low pressure and low volume. When we bought the house 2.5 years ago, there was/is still a Grundfos pressure booster pump in the crawlspace. The model # is MQ3-35.
About 6 months ago, it began leaking. At that time, I learned that many people install these thinking they have low pressure when they really have low volume. My static pressure w/o the pump was between 20-28psi, sometimes up to 32 psi depending on the time of day. I'm told that my pressure w/o the pump is borderline low but with the pump, the post-pump pressure was about 80-90psi which is too high and likely caused the pump to leak. So... I installed a pressure reducing valve *before* the pump so the input pressure would only be 15psi thus reducing the output pressure to an acceptable level and eliminating the leak. It worked.
All of that information may be useless but I wanted to share in case it matters for my real question. The Grundfos pump has officially bit the dust today (Motor/Bearing) and I am wanting to know the pro's and con's of the following 3 options and any suggestions if there is a 4th or 5th option that would be better.
1. Replace it with a new identical pump. (This would be easiest for me but I've learned these Grundfos pumps don't have the best reputation)
2. Ditch it and get a traditional pump with pressure tank. (I have plenty of room in the crawlspace)
3. Get a CSV setup
We are a family of 4 with high water usage. My wife and kids are home all day every day and water is used in large and small quantities regularly throughout the day. I'd estimate that 1 hour rarely goes by w/o water being used. My wife takes eternal showers and my kids take baths and have to pee every 5 minutes I swear.
Thank you! I look forward to any responses and help you might have!
