shower pump

just wondered if anyone would have any idea of the cost involved to supply and fit a 2 or 3 bar pump to a 2 story house?

decent pump c 250/275 euro

b+q plastic stuff c 130/160

fitting depends on where u want it put: is it just splicing into the feeds in the hot press, with power from immersion circuit?

If so be aware of the potential noise issue, particularly in a timber floored/timber internal walled house.

Also if u can dont include the head in the pumped circuit, when you flush at 3pm the whole street will know what you are at:)

Also make provision for a switch to turn it off if u are on holidays, some insurance policies, deep in the detail, will exclude water damage from a pumped circuit that goes ga ga

thank you ircoha, really helpful post! i had a quote this morning for 650 to supply and fit. my house is plumbed very oddly so there is quite a lot of pipe work involved (thank you glenford builders,gggrrr) i will definately ask for a switch, so thank you for the tip!

That is a very good point. I am considering moving mine from the hotpress to the attic space directly above its present location. There I will have the space to mount the pump inside a large sound proofed box. It will not fix the problem of noise 100%, but it should be alot better. Note: The pump will have to remain lower than the header tank feeding it to stay working.

Interesting, I never thought of that! I guess you could simply feed it from a switched spur.

A standard pump needs to be below the height of the shower head.

Really?? I did not know that. Why is that?? I assumed that once the pump was below the tank that is feeding it that there would be no problem pumping to an outlet that is lower than the pump is mounted.

I might move it downstairs to the utility now!!

BTW I only do plumbing on my own house!!

To be perfectly honest ,I'm not very sure. I think it's something to do with the flow switch ,but I could be mistaken.

The more of a head there is on the pump the better ,in general.

Personally I'd always aim to put the pump out in a shed or somewhere solid. Putting the pump on a conctrete slab ,can reduce the noise a good bit aswell.

My understanding is that the switch is a pressure switch and it is looking for a drop in pressure to activate the pump. This pressure drop occurs when the shower tap is opened causing water to flow and consequently a pressure drop.

I know, but it is waking a 4 year old!!

Me too, but it is too late now. The builders were sh!t and would do nothing that we asked for so I am just fixing everything myself. Same old story!!!

Try a thin concrete slab under the pump ,anything with dead weight should kill the vibration.

Thanks!

A few comments here on different points raised.

If u move it too far the amount of wasted water, hot and cold, becomes an issue.

25mm/30mm rubber matting in theory will help deaden the sound:
I have been through all the permutations here:
First one in the hot press in the bathroom, the noise was horrendous: as a bachelor a real turn off for the g/fs:)

Next one was in attic space
next was on concrete slab in attic
next was on floor of boiler room.

Finally I went with a fully pressurised system with a single 6 bar cold water pump:
Result: Bliss/ marriage /kids:D

On the question of head: I will only discuss 2 kinds here, positive and negative

the switches are generally a flow switch and for a positive head pump therefore the shower head needs to be below the level of the water in the tank for the water to flow and start the pump. If this is not possible there are 2 solutions.

One is to install a negative head pump which is designed for this purpose but is very expensive
The other is to install an air switch on the bathroom which is pushed to start the ordinary, positive head pump
I have used the latter and it worked well.

Sorry ,just to add that the piping may also cause some noise.

It's easy to judge it yourself and see if the pipe is loose enough ,not to add to the vibration.

I think the hoses that come with the monsoon pumps are the most flexible.
