Weird pause in water pressure?
I had a deep well installed about 8 years ago (230'). The well was used exclusively for gardening up until 3 years ago when we built an addition to the house and I tapped into the underground line and plumbed it to the addition which is a laundry room and shower. For the past 3 days when taking a shower the water pressure drops to zero for about 20 seconds, then it returns to normal. This happens after about the first 10 minutes in the shower. The pressure tank and well head are located in a containment shelter outside. Does this sound like a pump going bad? or possibly the automated pressure switch which is 40/60 psi? I wish that I could see the pressure gauge when it occurs but I assume it drops to zero before kicking back in. Thanks for any thoughts on this.
