Shower Pump

[Martin]

Hello, I am currently installing a new power shower.

Set-up:

140 litre Hot Tank in Bedroom 223 litre Cold Tank in loft Shower in opposite corner of house to hot tank Salamander RSP45 1.3bar pump to be mounted in loft on concrete slab Mixer Shower Triton Warwick Hot feed to pump 22mm approx 4m run from No Stop Essex Flange Cold feed to pump 22mm approx 2.5m run Hot/Cold feed to shower 15mm approx 9m run from pump.

I have two concerns:

1. Will the pump be able to push water for 9m and still deliver a reasonable shower? Standard shower head not multi-function.
2. Will the noise of the pump propagate throughout the house. Or even into my neighbours house as its in the loft not too far from the party wall.

When I started this project I had no idea of the cost. Its just exceeded the £1000 mark and I've not finished yet. If your thinking of installing a power shower then below are the approx costs for each item:

Stone Resin Shower Tray £65 Mixer Shower £160 Shower Screen £330 Tiles £130 Pump £140

50 Gallon Tank with Bye Law Kit/Connectors/Isolators £150 Stand for 50 Gallon Tank £50 Pipe / Essex Flange £40

Not cheap and I may not get a decent shower from it. You may already have a 50 gallon tank. Not included is plaster / title adhesive / grout / Sealant / Cement / Exterior ply / Screws / Solder etc...

Thanks in advance for comments, Martin

1) There's no problem to a 30' run of 15mm pipe( I've used up to 60'), however I'd mount the pump adjacent to the hot tank and use 28mm where possible on the input side to reduce flow losses. It will also reduce the hot water requirement slightly if you are lucky. 2) I've noticed that some pump manufacturers specify a 2.3M head for the pump supply, so mounting below the hot tank may be preferred. 3) Pump noise can travel, mounting on a slab will probably help, but if it is a problem, then a felt lined box can help. Beware of ventilation problems. Regards Capitol

You may find a 1.3bar pump driving 9m runs of 15mm tube to be a bit disappointing. I would go for 22mm from the pump as well. If you haven't bought the pump yet, then I would go for a 1.8 bar model or more and buy a Stuart Turner one.

It shouldn't do significantly if you use flexible hoses and also antivibration mounts.
