 Water pressure
Author: Marcy (MA)

We have an issue with our water. We have a well, and when we run the hose outside, we have no water in the house. We shut the hose off, and water is back to normal inside, but our filter gets alot of dirt when this happens, and we have to keep cleaning it out. We had this issue last summer and had a plumber and well technician come, and neither found a problem. What is happening!

Could be a number of things, but most likely a restriction in your main water line somewhere, possibly a clogged screen on the pressure reducing valve if you have one. Or a clogged water filter will severely limit how much water you have.

When you use outside faucets, it increases total demand on your system, pulling in more sediment, clogging the filter faster.

On my well system, the outside faucets are supplied BEFORE the filtration/treatment system. In other words, I use "raw" well water outside.
The plants do not seem to notice the difference.

It could be a number of issues from an undersized pump, the various sizes of your pipes, the size of the filter media and the micron rating. It could be a zone valve or stop. When you verify the integrity of your system... you will discover a number of answers.

Let me clarify things a little more. We moved in to our home oct 1st 2010. Our first summer here, we used the ouside hose with no problems. We could run the hose and all the water inside worked just fine. We ended up buying a intex pool and filled it over night with the hose. After doing so, we started having water problems. Dirt filed up in the toilet tanks, and dirt was coming out in the water and pressure was low. No idea if we ran the well dry. This is when we also realized that when we would go to use the hose, the water inside would not work. The flow of water to our washing machine went to a trickle. I called in a plumber and well technician and they could not pin point a problem. Took a little while, but all finally went back to normal. Now again, we went to run the hose for the first time this yr, to find that yet again, when we use it, the water inside stops. And the filter casing fills almost halfway with dirt, so we end up having to clean it ip to 3 times a day. When we turn off the hose, water pressure returns to normal quickly, although it takes longer for some reason in the basement. I dont understand.

Is that filter after your well tank?

A residential well system works best when the well water is mineral-free and free radicals are not present. When the quality of your well waters is lesser then best, it will burden the pump, the delivery system and the faucets that it feeds. Adding filters can and will create resistance as the media becomes covered with impurities and debris.
I'm surprised that your plumber and well specialist didn't mention this effect to you during their evaluation.
I suspect (not being there) that you may have overtaxed your system when filling the pool, years back and the system never recovered. Also your water levels may be affected by your use and by environmental location.
This is all internet speculation that must be verified onsite to be factually accurate.

When using the hose your well is being over pumped. Your well is not supplying sufficient water for your demand by using a garden hose.

Is your pressure tank filled with sand? The abrasive action of dirt or sand running through the pump will shorten the life of the pump. The wear on the pump will reduce its GPM capacity.
