Ammonia smell from borehole was cured by a neighbour putting milking parlour cleaner down hole and flushing it out leaving for a wee week and water ok again

Oops fat finger typo ignore wee😱

Just to add our set up as an option.

We have a borehole 75meter deep, it was drilled over 20 years ago. No one has seen the pump since. It used to feed a pair of loft tanks which fed two bathrooms and a kitchen via a noisy Stuart turner booster pump.

This past year I swapped the loft tanks for a 2000 litre water tank in the garden. We now have an Ezidiver submersible pump in the garden tank. That is supplying the whole house with very good pressure for two showers and two bathtub.

There's a treatment unit between the tank and the house. We're lucky to only need a spun cotton filter and a UV tube.

Benefits:  the submersible pump is totally silent. We have a good store of water for the day the well pump breaks that is easily filled temporarily by tanker or rain water.

Big tank. Ours is 1200 litres. Our borehole recharge rate is very slow and the borehole very deep (147m) with the pump at 80m. We had a problem last summer when we had a house full of family so lots of water use where the alarm in the pump control went off. There are three water probs in the borehole and the water got low enough to trigger the alarm (which stops the submersible pump) Because it can take a while for the borehole to fill back up it meant we used a lot of the tank water. I disabled the top probe so it starts pumping again more quickly but still has the protection if the water gets low.

Might benefit from an accumulator in the house?

I thought about that but no room. The pipes come under the MVHR and it’s all very tight as it is.

Mine is in the shed outside. With all the filter stuff.

There’s plenty of pressure without the pump as our drinking water tap comes into a small accumulator in the garage and bypasses  the softener. The issue is the recharge rate so we would empty the hole throughout the day and it would take hours to refill hence the tank. In hindsight we ought to have fitted another accumulator in the garage and could have likely negated the need for the pump.

Yea, that’s doable. More about adding more capacity tbh.

If that’s still an option would get you better results.  And you could fit a much bigger acc’r.
