Home Boost

[wcavanagh]

Anyone used a home boost pump?

I live on the end of a VERY long run of 15mm water supply from the farm up the track. Flow is not great, want to install wet room with large shower head, so need good fllow.

Thus seems to fit the bill.

Do you main one of those dinky little that boosters for direct fed systems or the Grundfos home booster?

If the former then you have no chance of running a rain shower.

 

[wcavanagh]

Home-boost.co.uk I was looking at.

What options do I have?

The supply comes from the farm up the road, he is on mains. I pay him for my water.

If you want to run a large rain shower head you'll need to pipe it off your loft tank and use a pump. If you have a combi boiler rather than a hot water cylinder you're knackered

 

[wcavanagh]

Boiler I want to install can deliver 18 L per min oil

Without more information I would say you need the grundfos home booster or another breaker tank/pump combo. Or depending on the house pipe work and incoming pressure (not flow) then an accumulator.

 

[wcavanagh]

I've read accumulator may be an option. It is a rural cottage, a long, long way from the main, so new supply pipe is not an option, it's about 900m to the farm it is fed rom in 15mm.

I will do a flow rate test, today is the first day I got water on, and noticed the flow was not great. How do I check pressure?

Sorry just in the process of full refit. So now is time to think about these things.

 

[muggles]

To check the pressure, you'll need a pressure gauge. To check flow rate, time how long it takes to fill a bucket of known capacity.

 

[Dan Robinson]

For a full refit on a rural supply that is likely to be unreliable then I would be looking at a big storage tank and boost pump.

With an 18l/min combi it doesn't have to be a monster pump. Decent Stuart Turner Universal Monsoon with the cylinder mounted a foot or two above the tank.

Job done.

Don't forget to plumb a by-pass though.

 

[wcavanagh]

Well today I done some measurements. Results are not good.

Static Pressure 5 - 6 Bar
Dynamic Pressure 0.2 Bar

Flow Rate............


Ready........


6 Litres Per Min......


YES 6


Really need to consider my options on this one. As a good quality shower is the MOST important thing to me, bath I don't care about but it is all about the shower.

Just hire an excavator and relay the pipe with a big one.

Not a chance in hell on of its such a long run across several fields.

Several fields not a problem.
A neighbour of mine went 700m across fields to lay a pipe when I was plumbing his gaffe.

You can use a mole trenching pipe layer which is pulled behind a tractor.
It's very fast and miminal disturbance to the ground.
You basically jump into the tractor and drop the trencher, release the clutch and drive off. Simples. OOh and make sure plenty of pipe is on the coil. Half a days work mebbe.

Some of the geothermal guys use the same method to lay the ground loops!

For trenching nigh on a kilometer, half a days work

On the books, it is a 4 day job for water authority, on a prepared site.

Yeah that's right.
A tractor does about 4 mile per hour in first gear.

I take it you've never driven one? We own four from 45hp to 160hp. Do our own mole draining!
They can be a bit perplexing for city folk what with all the levers.
Things are done differently down on the farm where time is money.

A good excavator driver will average about 280-300 ft per hour digging a 48" deep trench.
We charge £35 per hour for our 17 ton komatsu and £45 for the 22 ton daewoo.
